Masimo Helps Clinicians at Renown Health Manage the COVID-19 Surge

Irvine, California – December 21, 2020 – Masimo (NASDAQ: MASI) announced today that Masimo is helping clinicians at Renown Health in Reno, Nevada, to address the COVID-19 surge, including through use of Masimo SafetyNet™, a remote patient management platform. Renown Health is using Masimo SafetyNet to help care for patients positive for COVID-19 recover at home – and to help notify clinicians of the need to intervene when patients exhibit signs of deterioration.

Masimo SafetyNet™

Renown Health is a non-profit integrated healthcare network serving Nevada, Lake Tahoe, and northeast California. Masimo SafetyNet, introduced earlier this year as part of Masimo’s efforts to help hospitals and clinicians combat the pandemic, is now in use at numerous institutions around the world. Renown Health uses Masimo Patient SafetyNet™ and Masimo Rad-97^® Pulse CO-Oximeters^® to provide bedside and remote oxygen saturation and respiratory and pulse rate monitoring and notification within their hospitals and at a state-of-the-art 700-bed Alternate Care Facility. The facility has expanded into an adjacent parking structure, turned into a makeshift general ward to accommodate the unprecedented surge of patients suffering from COVID-19. In addition, Renown was one of the first systems to implement Masimo SafetyNet to expand patient care from the hospital to the home.

"We at Renown are proud of our national reputation as an innovator in implementing new models, technology, and systems of care for the community,” said Tony Slonim, MD, DrPH, President & CEO. "We are working with some incredible partners, including Masimo, to transform care and demonstrate value in a way that appeals to patients and helps clinicians improve outcomes and reduce costs. Renown's Hospital-at-Home model of care technology enables patients to receive hospital-level care in the comfort of their own homes. This is especially critical for patients who are elderly, frail or vulnerable to complications."

"This type of technology is a game-changer in improving patient care," said Paul Sierzenski, MD, MSHQS, Chief Medical Officer, Acute Services, Renown Health. "Given the demand on our hospitals during this COVID-19 pandemic, we are pleased to provide appropriate patients with this telehealth solution, which assists in our management of patients with COVID-19 and allows patients the convenience of being in their own homes."

Renown has found particular benefit in using Masimo SafetyNet to spot possible deterioration in home-based patients' vital signs and intervene proactively, before their condition worsens. Dr. David Lemak, Section Chief for Urgent Care at Renown Medical Group-Ryland St., heads the team which conducts virtual telehealth visits with discharged patients. Recently, they noticed several drops in the oxygen saturation of Jim Cox, a 58-year-old patient who was being monitored at home as he recovered from COVID-19. Following a virtual visit with Dr. Lemak, Jim returned to the hospital, where cardiac complications could be addressed.

"I was excited to be one of the first patients chosen to use the Masimo SafetyNet 'hospital-at-home' technology," said Jim Cox of Reno. "The system was easy to use. I was able to monitor my own vital signs through the app on my cell phone, and was pleased with the virtual medical visits provided by Dr. Lemak, and the nurses monitoring my device. It was a relief to be back with my family, recuperating in my own bed and making my own meals."

"With Masimo SafetyNet," said Dr. Lemak, "we have access to continuous, meaningful data, without burdening our recovering patients, giving my team confidence that even when they're not physically present with us, our patients are in good hands. We're so grateful to have been able to help Jim – without this system, the outcome could have been very different." Jim added, "While I was at home, my medical condition did not improve. Without this device and the Renown staff checking in with me, I probably would have ignored my symptoms and tried to sleep it off. Instead, I was immediately admitted back to the hospital."

"Our patients at Renown have the most sophisticated and reliable respiratory monitoring available anywhere," said Jason Farnsworth, MBA, Director of Respiratory Care Services at Renown. "We know that physiologic monitoring improves outcomes and saves lives. The ability to extend that capability to patients in non-traditional settings and at home during this crisis is transformative. Our teams are excited to be able to help patients and their families – and ensure they receive the clinical support they need by using this technology and monitoring."

"To know that we can provide quality care for patients recovering from COVID-19, and help ease their transition back to their normal lives, where they can recover in the comfort of their own homes, is fantastic," said Mitchell Fong, Director of Telehealth Services at Renown. "Patients have shared that they enjoy being at home, sitting in their favorite recliner, enjoying a home-cooked meal and even transitioning back to remote work. If we can help people feel better, we feel better."

Joe Kiani, Founder and CEO of Masimo, said, "We are grateful to be able to partner with institutions like Renown Health to make a positive difference at this exceptionally difficult time. Like hospitals and doctors everywhere, Renown is doing their best to help as many patients as possible, and Masimo SafetyNet allows them to stretch their resources and keep much-in-demand in-hospital beds free for the most acute cases, without compromising their ability to keep track of lower-acuity patients efficiently and effectively at home. We look forward to continuing to collaborate with Renown Health in the future as we expand the ways that Masimo SafetyNet and our other monitoring and automation solutions can help Renown improve their patient care and outcomes."

Harnessing its expertise in noninvasive patient monitoring, automation, and telehealth solutions, Masimo developed Masimo SafetyNet – which combines hospital-grade tetherless pulse oximetry, continuous temperature measurement, and a remote data capture and surveillance platform – to help hospitals accommodate surges in COVID-19 patient volume and help lower-acuity patients recover at home and in other alternate care spaces. Masimo SafetyNet allows clinicians to monitor their patients' physiological status – including oxygen saturation, respiration rate, pulse rate, and temperature – from afar, at all times. Masimo SafetyNet can be rapidly deployed and easily scaled as needed, without additional hardware or network infrastructure, helping caregivers provide the best possible care during this pandemic.

Researchers Use Masimo ORi™, Oxygen Reserve Index, to Help Suppress Postoperative Hyperoxia in Patients Undergoing Breast Surgery

Neuchatel, Switzerland – December 14, 2020 – Masimo (NASDAQ: MASI) announced today the findings of an abstract recently presented at Euroanaesthesia 2020 in which Dr. Kumagai and colleagues at Iwate Medical University Hospital in Yahaba-cho, Japan investigated whether Masimo ORi^™, Oxygen Reserve Index, could be used to limit the extent of postoperative hyperoxia.¹ The researchers concluded that ORi helped “suppress hyperoxia, preventing hypoxia.”

Masimo Root^® with ORi^™

ORi, available outside the U.S., is a noninvasive and continuous parameter intended to provide insight into a patient’s oxygen status during moderate hyperoxia. Enabled by the multi-wavelength rainbow^® Pulse CO-Oximetry platform, ORi is provided alongside oxygen saturation (SpO₂), a clinically proven Masimo SET^® pulse oximetry measurement.

Noting that postoperative hyperoxia is associated with various adverse outcomes—including “acute lung injury, increased hospital mortality, and worse outcomes in patients with ischemic stroke”—the researchers sought to determine whether a noninvasive, continuous parameter could help clinicians assess the appropriate amount of supplemental oxygen to administer to surgical patients, so as to limit hyperoxia post-surgery. They divided 50 patients scheduled for breast surgery into a group receiving ORi-based oxygen treatment (group O) and a control group that received conventional postoperative oxygen treatment (group C). In group C, after extubation, oxygen was administered at a fixed rate (4 L/min); in group O, oxygen was administered at 4 L/min but decreased by 0.5 L/min if ORi > 0.00, until ORi was 0.00 for 30 minutes continuously. Blood gas analysis was performed at various intervals. Hyperoxia was defined as partial pressure of arterial oxygen (PaO₂) > 120 mmHg, and hypoxia as oxygen saturation (SpO₂) ≤ 94% for more than 1 minute.

The researchers found that PaO₂ was significantly lower in the ORi group both before patients left the PACU (mean 117.3 mmHg [one standard deviation 26.8 mmHg] in group O vs. 170.0 mmHg [42.8 mmHg] in group C) and the morning after surgery (107.5 mmHg [16.5 mmHg] in group O vs. 157.1 mmHg [28.4 mmHg] in group C); p < 0.01. No patients had hypoxia.

The researchers concluded, “Determining postoperative supplemental oxygen amount using ORi can noninvasively suppress hyperoxia, preventing hypoxia.”

ORi has not received FDA 510(k) clearance and is not available for sale in the United States.

New Study Associates Masimo SpHb^®, Noninvasive and Continuous Hemoglobin Monitoring, as Part of Pediatric Patient Blood Management, with Reduced ICU Stays and Postoperative Transfusion

Masimo Root^® with SpHb^®

Neuchatel, Switzerland – December 10, 2020 – Masimo (NASDAQ: MASI) announced today the findings of an abstract recently presented at Euroanaesthesia 2020 in which Dr. Saraçoğlu and colleagues at Marmara University in Istanbul, Turkey investigated the efficacy of Masimo noninvasive and continuous hemoglobin monitoring, SpHb^®, as part of the transfusion management of pediatric patients undergoing major surgery.¹ The researchers found that use of SpHb was associated with decreased rate of postoperative transfusion, reduced length of ICU stay, and other improved outcomes.

Noting that traditional methods of measuring hemoglobin and estimating blood loss as part of perioperative blood transfusion management are "time consuming" and may cause delays in decision making, the researchers sought to investigate whether use of a noninvasive, continuous method, Masimo SpHb, would have an impact on transfusion rates, morbidity, and mortality in pediatric patients undergoing craniosynostosis surgery. Pediatric patients aged 2-24 months were divided into a control group (n = 28), whose transfusion therapy was managed using intermittent blood gas analysis, and an experimental group (n = 27), whose transfusion therapy was managed using SpHb monitored with Masimo rainbow^® sensors connected to a Radical-7^® Pulse CO-Oximeter^®. In both groups, blood gas analysis was performed hourly during the perioperative period; in the SpHb group, when SpHb monitoring indicated a sudden decrease in hemoglobin, blood gas analysis was simultaneously performed.

The researchers calculated the following statistically significant (p < 0.05) results:

They found that the length of stay in the ICU was statistically significantly higher in the control group than the SpHb group. Postoperative drainage, red blood cell transfusion, and fresh frozen plasma transfusion in the ICU were also statistically significantly higher in the control group than the SpHb group. Lactate levels were higher in the SpHb group at the start of the operation, but higher in the control group at the end.

The researchers concluded, "Noninvasive continuous hemoglobin monitoring in major hemorrhagic surgeries in pediatric patients might be effective in reducing morbidity not only by reducing the amount of transfusion but also [by] leading to less metabolic and hemodynamic instability."

In other clinical studies, conducted with adult patients, continuous monitoring with SpHb as part of patient blood management (PBM) programs has been found to improve outcomes, such as reducing the percentage of patients receiving transfusions,² reducing the units of red blood cells transfused per patient,^3-4 reducing the time to transfusion,⁵ reducing costs,⁶ and even reducing mortality 30 and 90 days after surgery by 33% and 29%, respectively.⁷ The evidence of SpHb’s impact on outcomes spans the globe, representing 6 countries on 4 different continents.^2-8 Today, SpHb technology supports clinicians in over 75 countries around the world.⁹

SpHb is not intended to replace laboratory blood testing. Clinical decisions regarding red blood cell transfusions should be based on the clinician's judgment considering, among other factors, patient condition, continuous SpHb monitoring, and laboratory diagnostic tests using blood samples.

Masimo's COVID-19 Response Efforts Highlighted at California Life Sciences Association's Pantheon 2020

Masimo, the Only Patient Monitoring Company Included, Was One of Seven Featured California Innovators

Irvine, California– December 7, 2020 – Masimo (NASDAQ: MASI) is proud to have been one of seven California innovators featured at Pantheon 2020, the annual event at which the California Life Sciences Association (CLSA) brings together industry leaders in the life sciences to recognize outstanding achievements. Held virtually this year, Pantheon 2020, which took place last Thursday, was anchored by a series of videos and panels highlighting stories of scientific innovation, collaboration, and progress focused on celebrating efforts to combat COVID-19. Masimo, the only patient monitoring company featured, was also one of the three companies highlighted at CLSA's "Celebrating California Innovation" event, and at a session dedicated to exploring how Masimo SafetyNet™ is playing a key role in Masimo's efforts to help clinicians and hospitals around the world fight the pandemic.

Masimo SafetyNet™ with Radius PPG™ and Radius-T°™

Mike Guerra, President and CEO of CLSA, commented, "Masimo is an exemplary illustration of the resiliency and flexibility shown by life sciences companies when California and the world were faced with a global pandemic. The adaptability of their remote patient monitoring technology has saved lives and allowed patients to recover from their homes, thereby freeing up critically needed hospital beds."

In early 2020, harnessing its expertise in noninvasive patient monitoring, automation, and telehealth solutions, Masimo developed Masimo SafetyNet, a secure, home-based patient management platform combining hospital-grade tetherless pulse oximetry, continuous temperature measurement, and a remote data capture and surveillance platform. Designed to help hospitals accommodate surges in COVID-19 patient volume and help lower-acuity patients recover at home and in other alternate care spaces, Masimo SafetyNet allows clinicians to keep an eye on their patients' physiological status – including oxygen saturation, respiration rate, pulse rate, and temperature – from afar, at all times. Already in use at numerous institutions in the U.S. and beyond, Masimo SafetyNet can be rapidly deployed and easily scaled as needed, without additional hardware or network infrastructure, helping caregivers provide the best possible care as the pandemic worsens.

In his speech at Pantheon 2020, Joe Kiani, Founder and CEO of Masimo, said, "I want to thank CLSA for highlighting our work in helping with the global pandemic. I also want to take this time to say we're humbled by this, because in fact, the real heroes are the people on the front lines using the tools we create to help patients, especially those with COVID-19. We've never seen anything like COVID-19, but as a member of CLSA, we're proud to have used life sciences technology, mathematics, and engineering to do the work that we have; together we are making a difference in so many people’s lives."

Study Comparing Two Noninvasive Indicators of Fluid Responsiveness on Mechanically Ventilated Patients Finds Masimo PVi^® Effective and Advantageous

Researchers Preferred PVi for Being “Continuous, Operator-independent, and More Reliable” 

Neuchatel, Switzerland – November 30, 2020 – Masimo (NASDAQ: MASI) announced today the findings of a study published in the Ain-Shams Journal of Anesthesiology in which Dr. Diaaeldin Aboelnile and colleagues at Ain-Shams University in Cairo, Egypt compared two noninvasive methods of assessing fluid responsiveness in mechanically ventilated patients, dIVC and Masimo PVi^®.

Masimo Root^® with PVi^®

They found both methods to be “effective,” but determined that PVi was advantageous because of being “continuous, operator-independent, and more reliable than dIVC.”1 PVi, pleth variability index, is a measure of the dynamic changes in perfusion index that occur during the respiratory cycle.

Noting the importance of predicting responsiveness prior to fluid administration and the drawbacks of invasive and static methods of assessing responsiveness, the researchers sought to assess the effectiveness and reliability of PVi—which is noninvasive, dynamic, continuous, and can be measured using a pulse oximetery sensor—by comparing it to another noninvasive, but non-continuous, static method, ultrasound calculation of inferior vena cava distensibility index (dIVC). dIVC represents the percentage of variation in the inferior vena cava diameter during inspiration versus expiration. To that end, they monitored 88 adult, sedated, mechanically ventilated, intubated surgical patients using both PVi and dIVC. The patients were classified as fluid responders (48) or non-responders (40) by using the passive leg raising (PLR) test; patients whose cardiac index (CI) increased by 15% or more were considered responders. PVi was monitored using a fingertip sensor and a Masimo Radical-7^® Pulse CO-Oximeter^®; dIVC was measured using a Mindray M5 ultrasound probe. To assess their performance against an invasive method, the researchers also measured central venous pressure (CVP).

The researchers calculated the following results for the three parameters:

Based on these findings, the researchers concluded, “The results of our study showed that assessment of PVi and dIVC noninvasively were good predictors for fluid management and responsiveness prediction using PLR technique in the surgical ICU mechanically ventilated patients.” They continued, “PVi and dIVC can be used in the assessment of fluid responsiveness of the intubated ventilated sedated patients with sinus rhythm in the ICU, and both methods are noninvasive and can be performed at the bedside, but PVi has the advantage of being continuous, operator-independent, and more reliable than dIVC.”

Study Investigates Effects of Patient Blood Management Program with Masimo SpHb^®, Noninvasive, Continuous Hemoglobin Monitoring, on Postoperative Cancer Patients

Patient Blood Management with Masimo SpHb Increased Transfusion Appropriateness and Decreased RBC Units Transfused per Patient 

Neuchatel, Switzerland November 16, 2020 - Masimo (NASDAQ: MASI) announced today the findings of a study published in Blood Transfusion in which Dr. Lucia Merolle and colleagues at the Azienda USL-IRCCS of Reggio Emilia, Italy investigated the impact of applying a patient blood management program, including use of noninvasive and continuous hemoglobin monitoring, Masimo SpHb^®, to the care of postoperative cancer patients.¹ The study found that using SpHb as part of a patient blood management program not only increased how often postoperative blood transfusions were appropriate, but decreased the total and mean number of blood units transfused per patient.

Patient blood management (PBM) is "an evidence-based, multidisciplinary approach aimed at optimizing the care of patients who might need blood transfusions." Recognizing that PBM might have specific benefits for surgical oncology patients, the researchers implemented a two-step PBM program and compared three groups of postoperative adult cancer patients who underwent major surgery between 2014 and 2017. Step 1 PBM included seminars and training designed to teach semi-intensive post-surgical personnel the principles of PBM. Step 2 PBM added the use of SpHb monitored with Masimo Radical-7^® Pulse CO-Oximeters^® with SpHb. Audit 1 reviewed data for 200 patients whose post-surgical care did not incorporate PBM. Audit 2 was of 200 patients whose care incorporated Stage 1 PBM, and Audit 3 was of 200 patients whose care incorporated Stage 2 PBM along with continuous SpHb monitoring.

Using guidelines developed by the Italian Society of Transfusion Medicine and Immunohaematology (SIMTI), the researchers found that transfusion appropriateness rose from 38% in Audit 1 patients, to 75% in Audit 2 patients (Step 1 PBM), to 79% in Audit 3 patients (Step 2 PBM, with SpHb). The total number of red blood cell (RBC) units transfused was similar for Audit 1 and Audit 2 patients (52 and 58 units, respectively), but dropped to 39 units with the addition of SpHb monitoring to PBM (Audit 3). The mean number of RBC units transfused was the same for Audit 1 and Audit 2 patients (1.8 units/patient), but again, with the addition of SpHb monitoring (Audit 3), the mean dropped to 1.3 units/patient.

The researchers concluded, "Our PBM bundle positively impacted RBC transfusion appropriateness in post-surgical cancer patients, both in terms of quality and quantity. A structured PBM program specifically dedicated to surgical oncology should cover the entire perioperative period and might further improve transfusion appropriateness in these patients. The publication of guidelines on the management of anemia in surgical oncology should be a priority."

In other clinical studies, continuous monitoring with SpHb as part of PBM programs has been found to improve outcomes, such as reducing the percentage of patients receiving transfusions,² reducing the units of red blood cells transfused per patient,^3-4 reducing the time to transfusion,⁵ reducing costs,⁶ and even reducing mortality 30 and 90 days after surgery by 33% and 29%, respectively.⁷ With the addition of the Italian study, the evidence of SpHb's impact on outcomes spans the globe, representing 6 countries on 4 different continents.^1-7 Today, SpHb technology supports clinicians in over 75 countries around the world.⁸

SpHb is not intended to replace laboratory blood testing. Clinical decisions regarding red blood cell transfusions should be based on the clinician's judgment considering, among other factors, patient condition, continuous SpHb monitoring, and laboratory diagnostic tests using blood samples.

Masimo Founder and CEO and Co-Inventor of Measure-Through-Motion Pulse Oximetry, Joe Kiani, Awarded by the Ibero-American Society of Neonatology for Improvements to Neonatal Health in Latin America

Irvine, California - November 9, 2020 - Masimo (NASDAQ: MASI) announced today that its Founder, Chairman, and CEO, Joe Kiani, has been honored by the Ibero-American Society of Neonatology (SIBEN) at its 17^th Annual Congress (this year held virtually) with the Award for Improvement of Neonatal Health in Latin America. In her award presentation, SIBEN Scientific Group member Dr. Susana Rodríguez praised Mr. Kiani for his lifelong dedication to improving newborn care.

SIBEN, founded in 2004, is dedicated to improving newborn care throughout Latin America – where 15 babies die every hour, with 60% of those who die before their first birthday dying during the first 28 days after birth.¹ SIBEN is comprised of more than 2,000 healthcare professionals associated with neonatal care.

Dr. Rodríguez noted that Mr. Kiani's commitment to neonatal care started with the invention, in 1995, of Masimo Signal Extraction Technology^®, or SET^®, pulse oximetry, whose breakthrough ability to measure through motion and low perfusion led to remarkable improvements in neonatal care. In particular, use of SET^® has played a key role in reducing the rate of neonatal blindness (retinopathy of prematurity). In 2003, Dr. Augusto Sola (Managing Director of SIBEN) and colleagues showed that using a new protocol with Masimo SET^®, clinicians reduced ROP to nearly zero over five years.² A later study showed that the protocol's success depended on SET^® technology, as the same protocol with a competing pulse oximeter did not reduce ROP.³ Today, SET^® pulse oximetry is used to monitor more than 200 millions patients each year,⁴ and has been shown, among other benefits, to help improve critical congenital heart disease (CCHD) screening in newborns.⁵

Continuing, Dr. Rodríguez highlighted how Mr. Kiani's creativity and vision have led to many additional medical advancements in the years since, with Masimo, which recently celebrated its 31^st anniversary, remaining at the forefront of global medical innovation. Mr. Kiani has long championed the importance of patient safety, and in 2013 created The Patient Safety Movement Foundation, dedicated to achieving zero preventable deaths by 2030. To date, more than 4,700 hospitals in 50 countries have committed to this goal—and an estimated 93,000 lives are being saved annually.⁶ Among other honors and awards, Mr. Kiani has been named SafeCare’s Person of the Year and one of "50 Experts in Patient Safety" by Becker’s Hospital Review. He received an Honorary Doctorate of Science from Chapman University, and is an Honorary member of the Mexican Academy of Surgery.

In his acceptance speech, Mr. Kiani said, "Thank you to all the neonatologists and the care providers around neonates. There’s so much apathy, and I think that's the biggest hurdle to improving patient care – but not with neonatologists and neonatal nurses. You have never stopped amazing me with how much you care for our babies, your patients. I also want to thank SIBEN for the incredible work you're doing to bridge the gap between knowledge and what's practiced. You know better than I that what’s common practice is unfortunately not always best practice – and your work – to educate, educate, educate – is critical in bridging that gap, so more babies get the best care possible. I want to thank Dr. Susana Rodríguez and the board of SIBEN for honoring me with this meaningful award."

Kiani continued, "I want to tell you how blessed I feel to have friends like Mohammad Diab and Dr. Augusto Sola, who helped me with a great innovation, not only to innovate our measure-through-motion pulse oximetry, but to innovate a way to use it to help so many babies. That gift, which these two incredible friends have given me, has allowed me to feel fulfilled, and even though I know I'm just a speck in time and in space, at least we’ve been together, my dear friends, a useful speck, that may have given birth and happiness to more specks to enjoy the joy and pain of life, which is precious. Thank you again for this incredible award. Thanks for encouraging me to try harder, and for encouraging others to try harder, to do the right thing."

Masimo Announces Limited Market Release of Radius VSM™

Versatile, Wearable Continuous Monitoring Solution Provides Masimo SET^® Pulse Oximetry, Proprietary Noninvasive Blood Pressure, Body Temperature, Respiration Rate, and Electrocardiography

NEUCHATEL, SWITZERLAND - November 2 2020 - Masimo (NASDAQ: MASI) announced today that Radius VSM™, a wearable, tetherless vital signs monitor, has received CE marking and is being released in limited European markets. The versatile, expandable Radius VSM provides the ability to monitor a wide variety of physiological measurements, including continuous SET^® pulse oximetry, noninvasive blood pressure, body temperature, respiration rate, and electrocardiography (ECG). Designed on a wearable, modular platform, Radius VSM features can be scaled to accommodate surges in patient volume and for use across the continuum of patient care, based upon each patient’s needs and level of acuity. For additional versatility, Radius VSM can operate as a self-contained device or be used wirelessly with Masimo bedside monitors and patient surveillance systems – automating the integration of expanded monitoring and the transfer of continuous monitoring data to electronic medical records (EMRs)

As a comprehensive, scalable solution, Radius VSM has potential clinical utility in a multitude of care scenarios while also encouraging ambulation and freedom of movement, which studies have shown to be a key factor in more rapid patient recovery.^1-2 Configurable with a variety of modules and noninvasive sensors designed to prioritize comfort and ergonomics, care teams can seamlessly increase or decrease the technologies monitored based on each patient's needs, without additional bedside equipment, infrastructure, or tethered connections. Radius VSM offers the following wearable technologies:

• • Clinically proven Masimo SET^® Measure-through Motion and Low Perfusion™ pulse oximetry,³ including oxygen saturation (SpO₂), pulse rate (PR), perfusion index (Pi), PVi^® fluid responsiveness, and RRp^® plethysmographic respiration rate
• • ECG with heart rate, respiration rate, and advanced lethal arrhythmia detection using 3-leadwire single-patient-use electrodes offering 6 ECG waveforms: I, II, III, aVR, aVL, and aVF
• • Measure-on-inflation noninvasive blood pressure that features single-patient-use cuffs, customizable scheduling (eliminating the need for periodic manual clinician measurement), and variable inflation speeds; for example, quicker for ambulating patients and slower for resting patients, minimizing the possibility of sleep disruption
• • Continuous body temperature measurements with notifications when clinician-specified temperature thresholds are breached
• • RRa^® continuous acoustic respiration rate monitoring using rainbow Acoustic Monitoring^®, which converts the acoustic patterns caused by the patient's airflow into breath cycles to calculate respiration rate and visualize an acoustic respiration waveform

Radius VSM features a high-resolution touchscreen and the ability to store and display up to four hours of trend and waveform data on the device itself, providing additional clinical context at the point of care for nurses, therapists, and doctors when interacting directly with patients. In addition, Radius VSM's rechargeable battery lasts over twelve hours between charges; two devices are supplied for each bedside to provide uninterrupted functionality. Radius VSM has a rugged, durable exterior designed to withstand busy hospital environments and drops of up to one meter, and is water resistant.

Radius VSM can communicate via Bluetooth^® to the Root^® Patient Monitoring and Connectivity Hub at the bedside, for enhanced visibility on Root’s display. The device can also independently communicate via Wi-Fi to the Patient SafetyNet™ Supplemental Remote Monitoring and Clinician Notification system, enabling use as a patient surveillance system monitored from central viewing stations. The ability to track continuous vital signs and telemetry data from afar is an especially relevant feature for clinicians in the context of COVID-19 and other contagious conditions, where staying informed of patient status while minimizing the risk of cross-contamination can be essential to effective patient care. In addition, automated remote data transfer from Radius VSM to electronic medical records (EMRs) ensures that up-to-date physiological data is always available to clinicians and systems throughout the hospital, without the need for time-consuming manual transcription.

Joe Kiani, Founder and CEO of Masimo, said, "Radius VSM offers the reliability and accuracy of a bedside monitor with the flexibility of a wearable device, thus opening the door to numerous new uses, made possible by its unique scalability and broad range of automated, continuous measurements. We’re excited for clinicians and patients in Europe to experience the advantages of Radius VSM, and look forward to making it available to the rest of the world as regulatory clearances are obtained."

Dr. Augusto Sola, Masimo VP of Medical Affairs for Neonatology, Honored by the American Academy of Pediatrics with Pioneer Award

Dr. Sola Pioneered New Protocol Using Masimo SET^® Pulse Oximetry That Dramatically Reduced Blindness and Eye Damage in Neonates

IRVINE, CALIFORNIA – October 19, 2020 - Masimo (NASDAQ: MASI) announced today that Augusto Sola, MD, Vice President of Medical Affairs for Neonatology at Masimo, has been awarded the 2020 Pioneer Award, Section of Neonatal Perinatal Medicine, by the American Academy of Pediatrics (AAP). The honor recognizes the groundbreaking achievements and contributions Dr. Sola has made, using his Masimo SET^®-based protocol, to improve the health and well-being of newborn infants.

Dr. Sola's impressive career in neonatology has improved the lives of countless newborns in the U.S., Latin America, and across the world. Dr. Sola's innovative research on oxygen administration and monitoring oxygen saturation in preterm infants has played a key role in reducing the rate of neonatal blindness (retinopathy of prematurity) and our understanding of the impact of various neonatal practices on the developing brain. Dr. Sola has published 130 original articles in peer-reviewed journals, 390 review articles, and 5 neonatology textbooks, as well as delivered more than 3,500 lectures to research and clinical groups around the world. Dr. Sola also founded the Ibero-American Society of Neonatology (SIBEN), dedicated to continuous quality improvement in neonatal care throughout the Americas.

Dr. Sola received his MD at Buenos Aires University School of Medicine and completed his Pediatric Residency and Chief Pediatric Residency at the University of Massachusetts, followed by a Neonatal Fellowship at the University of California, San Francisco. In neonatal practice since 1974, Dr. Sola has been Professor of Pediatrics at Buenos Aires University Medical School, the University of California, San Francisco, the University of California, Los Angeles, and Emory University. In addition to his position at Masimo, Dr. Sola continues to work directly with critically ill newborns.

Dr. Sola’s seminal work was done in 1998 at Cedars-Sinai Medical Center in Los Angeles. The results, published in 2003 by Drs. Sola, Wright, and Chow, showed that using a new protocol with Masimo SET^®, clinicians reduced ROP to nearly zero over five years.¹ Dr. Sola and colleagues later showed at Emory that the protocol's success depended on SET^® technology, as the same protocol with a competing pulse oximeter did not reduce ROP.² Dr. Sola’s work on the reduction of ROP through oxygen saturation targeting has now become the standard of care.^3-5

Dr. Sergio Golombek, MD, MPH, Professor of Pediatrics at New York Medical College, Neonatologist, Ex-President of SIBEN, and AAP member, commented, "In 1952, a Chicago newspaper wrote: 'The best friend a baby ever had,' referring to pediatrician Isaac A. Abt, MD, FAAP (1867-1955), founder of the AAP and its first president in 1930. He was known as a leading clinician, academic, advocate, promoter, writer, and leader. I think this has been overcome by Dr. Sola, who is, in my opinion, the best friend of a baby and his or her parents and of the many neonatal professionals and trainees whom he trained!"

Joe Kiani, Founder and CEO of Masimo, said, "We are incredibly proud of Dr. Sola, a brilliant and caring doctor whom I have had the privilege of knowing for many years. Dr. Sola's pioneering work on the oxygen saturation of neonates has made a significant impact on the prevention of blindness in infants, and his contributions to our understanding of neonatal physiology are vast. It is only fitting that the American Academy of Pediatrics has chosen to honor him. We are grateful to benefit from his expertise at Masimo, which has been especially dedicated, ever since its founding, to improving outcomes for the youngest and most fragile patients. Congratulations, Dr. Sola, on this well-deserved recognition."

Researchers Use Masimo ORi™, Oxygen Reserve Index, to Predict the Need for Postoperative Oxygen Therapy in Pediatric Patients with Obstructive Sleep Apnea

Neuchatel, Switzerland – October 12, 2020 - Masimo (NASDAQ: MASI) today announced the findings of an abstract recently presented at ANESTHESIOLOGY^® 2020, the Annual Meeting of the American Society of Anesthesiologists (ASA). In this independent, retrospective study, researchers investigated whether Masimo ORi™ (Oxygen Reserve Index) could predict whether children with obstructive sleep apnea syndrome (OSAS) undergoing tonsillectomy required postoperative oxygen therapy.

ORi, available outside the U.S., is a noninvasive and continuous parameter intended to provide insight into a patient’s oxygen status during moderate hyperoxia. Enabled by the multi-wavelength rainbow^® Pulse CO-Oximetry platform, ORi is provided alongside oxygen saturation (SpO₂), a clinically proven Masimo SET^® pulse oximetry measurement.

Dr. Yoshimi Inagaki and colleagues at Tottori University in Yonago, Japan sought to determine whether Masimo ORi could serve as a useful predictor of the need for postoperative oxygen therapy (POT). They enrolled 45 pediatric patients with OSAS, ranging from 7 to 120 months, who were anesthetized with sevoflurane and monitored with ORi while undergoing tonsillectomy.

Of the 45 patients, 16 required POT. For those 16, the mean lowest ORi and SpO₂ values were 0.28 and 93%, respectively. For the remaining patients, who did not receive POT, the mean lowest values were 0.64 and 97%, respectively. The researchers calculated sensitivity and specificity for ORi predicting when POT would not be needed of 0.815 (95% confidence interval 0.5435 – 0.9595) and 0.9310 (95% confidence interval 0.7723 – 0.9915), respectively.

The researchers concluded that ORi is "likely to become an index of POT in pediatric patients with OSAS." They also noted, "In children with OSAS, [the] requirement of POT following tonsillectomy and adenoidectomy is probably able to be predicted on the basis of the results of this retrospective cohort study."

ORi has not received FDA 510(k) clearance and is not available for sale in the United States.

Masimo Announces Consumer Launch of the Radius T°™ Continuous Thermometer, a More Convenient Way to Keep Track of Fever

Wearable, Wireless Sensor Provides Hassle-Free Continuous Body Temperature Measurements

Irvine, California – October 5, 2020 - Masimo (NASDAQ: MASI) today announced the launch of the Radius T°™ Continuous Thermometer for consumers. Unlike spot-check, episodic thermometers, the wearable, wireless Radius T° measures body temperature continuously, seamlessly transmitting data and customizable temperature notifications to the user's smartphone – helping caregivers, such as parents, monitor loved ones' temperatures even while they sleep.

Radius T° represents a paradigm shift in thermometry by making it continuous, wearable, and hassle-free. Traditional periodic and invasive methods depend on the user repeatedly conducting a series of steps that can interrupt daily activities, including sleep, and can miss body temperature trends and patterns. With a traditional thermometer, a person may only notice a spike in temperature hours after a spike has occurred, or may not even become aware of it if it is during sleep. By contrast, Radius T° continuously and seamlessly measures temperatures using a small, inconspicuous, wearable sensor that can be easily applied to anyone from children to elderly adults – with no action needed after initial application to the skin. Radius T° eliminates manual measurements while providing continuous insight into changes in the user's temperature and helps users understand which way their temperature is trending. In addition, Radius T° uses proprietary algorithms to provide body temperature measurements for users five years or older that approximate oral temperature, not just external skin temperature. Radius T° provides temperature measurements with laboratory accuracy within ±0.1°C, whereas other oral thermometry solutions typically have laboratory accuracy within ±0.2°C.

Earlier this year, Masimo launched Radius T° as part of the Masimo SafetyNet™ remote patient management solution, for use both in hospitals and by patients at home. Dr. Neal Fleming, M.D., Ph.D., Vice Chair for Education in the Department of Anesthesiology and Pain Medicine at UC Davis Health, commenting on his experience using Radius T°, said, "Radius T° is noninvasive and convenient for patients. I do not have to interrupt their daily activities or their sleep and it provides me continuous trend data that is a powerful guide to patient care. It makes it easier for me to recognize possible changes in their symptoms."

Flexible and slim, each disposable Radius T° sensor can be worn comfortably for up to eight days, and is water resistant during shower and exercise. Users are free to carry on with their daily activities and sleep, without interruption or hassle – all while Radius T° continuously collects temperature data. Using built-in Bluetooth^®, the sensor easily pairs with the Masimo Radius T° App on the user’s smartphone, providing real-time temperature values with user-definable automatic notifications (for example, when temperature exceeds a certain user-selected threshold or if it spikes), as well as detailed historical trending data, revealing the baseline and fluctuation patterns unique to each person that can help users determine whether a rise in temperature warrants action. In addition, the user-friendly Masimo Radius T° App can support multiple family member profiles and can be easily set to schedule medication reminders.

Joe Kiani, Founder and CEO of Masimo, said, "We're excited to expand our growing line of consumer solutions, which includes MightySat^® and Masimo Sleep™, with the Radius T° Continuous Thermometer. For years, clinicians have trusted Masimo technology to monitor patients in the hospital. With Radius T° and our other consumer solutions, we're bringing our expertise and experience in accurately and reliably measuring physiological data from the hospital to the home."

Radius T° is not FDA 510(k) cleared. The device is marketed under the FDA's Enforcement Policy for Clinical Electronic Thermometers During COVID-19. Radius T° is CE marked.

Masimo Announces FDA Clearance of the Rad-G™ Pulse Oximeter

Rugged Handheld Device Provides Clinically Proven Masimo SET^® Pulse Oximetry and Respiration Rate Monitoring

Irvine, California – September 28, 2020 - Masimo (NASDAQ: MASI) today FDA clearance of the Rad-G™ Pulse Oximeter, a rugged handheld device that provides clinically proven SET^® pulse oximetry, respiration rate from the pleth (RRp^®), and other vital parameters for both spot-checking and continuous monitoring. With its long-lasting rechargeable battery, robust rubber casing, light weight, and a convenient new direct-connect sensor capable of monitoring both adults and children, Rad-G makes it easier for clinicians to quickly assess patients and make informed care decisions anywhere pulse oximetry or vital signs checking is needed in a compact, portable form factor. Providing the ultimate in handheld versatility, Rad-G can be used in a variety of settings, including but not limited to physicians' offices, outpatient services, long-term care facilities, wellness clinics, first-response scenarios, and limited-resource environments.

Launching alongside the device, the new multipurpose, direct-connect Rad-G Sensor is indicated for monitoring both adult and pediatric patients. By eliminating the need to stock and carry multiple sensor types, the Rad-G Sensor further increases Rad-G's versatility and ease of use, especially in more challenging field environments. In addition to this innovative new sensor, Rad-G is compatible with the vast portfolio of Masimo reusable and single-patient-use sensors, maximizing its flexibility and offering clinicians the ability to customize the solution based on the unique needs of each care setting.

First developed in partnership with The Bill & Melinda Gates Foundation as a spot-check device for global use, the 2021 Rad-G expands on its predecessor's capabilities with the addition of alarms and thus the ability to provide continuous monitoring – without sacrificing any portability, convenience, or ruggedness. Rad-G's rechargeable battery provides an impressive 24 hours of use between charges, allowing clinicians to work in outdoor, transport, and emergency scenarios with confidence that Rad-G will continue to function hour after hour. All the while, the high-resolution screen displays a continuous pleth waveform and its fully configurable, audible alarms help alert clinicians to changes in patient status that may require their intervention.

In addition to Masimo SET^® oxygen saturation (SpO₂), pulse rate (PR), perfusion index (Pi), and pleth variability index (PVi^®), Rad-G is also notable for its ability to use the same sensor to monitor respiration rate from the plethysmograph, with RRp. With breathing difficulty generally considered one of the earliest signs of patient deterioration, Masimo hopes that the availability of RRp on Rad-G may play a role in assisting clinicians and public health officials as they seek to combat respiratory-related illnesses, including pneumonia and COVID-19.

SpO₂ and PR monitoring on Rad-G is provided using clinically proven Masimo SET^® Measure-through Motion and Low Perfusion™ pulse oximetry, which has been shown in over 100 independent and objective studies to outperform other technologies.¹ SET^® is estimated to be used on more than 200 million patients a year² and is the primary pulse oximetry at 9 of the 10 hospitals that top the 2020-21 U.S. News and World Report Best Hospitals Honor Roll.³ With Masimo SET^® technology in Rad-G, clinicians have access to hospital-grade, accurate pulse oximetry measurements in the palm of their hands.

Joe Kiani, Founder and CEO of Masimo, said, "With the Rad-G Pulse Oximeter, we set out to create an accessible, high-quality care solution that clinicians can rely on in a multitude of care settings. We are bringing our expertise in pulse oximetry to a smaller, more lightweight, rugged, and versatile handheld device – without sacrificing any of the advantages that help provide clinicians with critical insights into patient status.

Masimo O3^® Regional Oximetry Receives FDA Clearance for Somatic Applications and Measurement of Relative Changes in Cerebral Hemoglobin

Irvine, California – August 31, 2020 - Masimo (NASDAQ: MASI) today announced that O3^® Regional Oximetry has received FDA clearance for expanded use in monitoring somatic tissue oxygenation saturation in all patient populations and monitoring relative changes in hemoglobin, oxyhemoglobin, and deoxyhemoglobin in adult brains. With this FDA clearance, O3 is now indicated for use in both cerebral and somatic applications, both in the U.S. and in CE mark countries, for all patient populations.

O3 Regional Oximetry provides regional or tissue hemoglobin oxygen saturation with a trending specification of 3% A_RMS* (cerebral and somatic, all ages) and absolute accuracy specifications of 4% A_RMS (cerebral, adults) and 5% A_RMS (cerebral, pediatric patients) through the use of O3 multi-wavelength sensors and O3 Regional Oximetry near-infrared spectroscopy (NIRS) technology. Unlike peripheral pulse oximetry, which reflects the body's general arterial blood oxygenation, O3 provides information about the local tissue’s hemoglobin oxygen saturation, both in cerebral and somatic applications. This information provides additional insight that may help inform clinicians of changes in cerebral or somatic tissue oxygen levels. Monitoring renal tissue oxygenation in neonates has been found to help provide early warning of renal dysfunction.¹ Monitoring both brain and somatic tissue oxygenation simultaneously may further improve clinicians' ability to provide rapid and accurate care.²

André Denault, MD, PhD, Department of Anesthesiology, Critical Care Program at the Montreal Heart Institute and Central Hospital of the University of Montreal, said, "There is a growing interest in the use of somatic NIRS owing to the association of cerebral and somatic desaturation with unfavorable outcomes in shock states. As an addition to O3 cerebral oximetry, the somatic component could serve as an earlier warning of impaired tissue perfusion. Somatic NIRS has been validated as a monitor of peripheral perfusion and shows an excellent correlation with peripheral perfusion compared with radionuclide plethysmography. As previously reported,³ cerebral and somatic NIRS combined with bedside whole-body ultrasound can help in early detection of different types of shock to formulate proper therapeutic strategies."

Along with FDA clearance for somatic monitoring, the O3 measurements ΔcHb, ΔO₂Hb, and ΔHHb are cleared for the monitoring of relative changes in oxygenated hemoglobin (ΔO₂Hb), deoxygenated hemoglobin (ΔHHb), and total hemoglobin (ΔcHb) in adult brains. With the expanded indications for ΔcHb, ΔO₂Hb, and ΔHHb, clinicians gain information that may provide insight into the dynamic relationship between oxygen and hemoglobin in the brain that brain oxygenation saturation (rSO₂) alone may not provide.

Dr. Aamer Ahmed, FRA FESC FACC, Consultant Cardiovascular Anesthesiologist at University Hospitals of Leicester, UK, said, "When using regional oximetry to monitor the brain, rSO₂ helps track the oxygenation state of the brain, but understanding the dynamic variations in rSO₂ is even more valuable. Changes in rSO₂ may be a function of a change in hemoglobin or perfusion, or may result from an oxygen desaturation event. In my practice, I use Masimo O3 ΔcHb, ΔO₂Hb, and ΔHHb to gain insight into the relative changes in hemoglobin and perfusion in the brain to help enable earlier detection and intervention during adverse changes to cerebral blood flow."

O3 seamlessly integrates with Masimo SedLine^® brain function monitoring on the Root^® Patient Monitoring and Connectivity Platform, a powerful, expandable hub that integrates an array of technologies, devices, and systems to provide multimodal monitoring and connectivity solutions. Root's plug-and-play expansion capabilities allow clinicians to simultaneously monitor with O3, SedLine, and other measurements, such as SET^® Measure-through Motion and Low Perfusion™ pulse oximetry, providing clinicians with expanded visibility of oxygenation status. Additional modalities available on Root include advanced rainbow^® noninvasive measurements such as total hemoglobin (SpHb^®) and PVi^® (an indicator of fluid responsiveness), NomoLine^® capnography, and more – all via an easy-to-interpret, customizable display. Using Root in combination with Masimo Iris Gateway^®, monitoring data from O3 can be automatically charted in electronic medical records (EMRs).

Joe Kiani, Founder and CEO of Masimo, said, "O3's expanded indication as a monitor of the oxygenation and deoxygenation components of cerebral tissue, along with the oxygen saturation of somatic tissue, represents an important milestone in helping clinicians and researchers shed additional light on how the body utilizes oxygen and in uncovering organ hypoxemia."

New Studies Investigate the Accuracy of Noninvasive, Continuous Hemoglobin Monitoring with Masimo SpHb^® on Neonates

Neuchatel, Switzerland – August 19, 2020 - Masimo (NASDAQ: MASI) today announced that in a study recently published in the Journal of Tropical Pediatrics, researchers evaluating Masimo SpHb^® (noninvasive, continuous hemoglobin monitoring) on neonatal patients concluded that the technology "offers reliable Hb [hemoglobin] values, which are comparable with the more traditional tHb [invasive venous blood sampling]."¹

Noting that "iatrogenic anemia caused by diagnostic blood sampling is a common problem in intensive care units," especially in neonatal intensive care units (NICUs), and that diagnostic blood sampling also has implications for infection control and health care costs, Drs. Halil Kazanasmaz and Mahmut Demir at Harran University in Sanliurfa, Turkey sought to assess the efficacy of noninvasive, continuous hemoglobin monitoring with SpHb on neonates by comparing it to conventional tHb. To investigate this, they studied 310 neonatal patients in a level III NICU in Turkey. Immediately after patients had blood drawn for tHb analysis using a hematological laboratory analyzer, their SpHb values (alongside other noninvasive measurements) were recorded using a Masimo Radical-7^® Pulse CO-Oximeter^® with rainbow^® sensors placed on the neonate’s left foot.

Using Bland-Altman analysis, the researchers found a mean bias of 0.05 g/dL between tHb and SpHb, with limits of agreement of -1.85 and 1.96 g/dL. Based on the study results, they concluded, "In this study, it was found that the SpHb measurement method could yield reliable results similar to tHb measurement method in the newborns. It is thought that the SpHb method may have a complementary role in reducing unnecessary blood sampling and therefore iatrogenic anemia, especially in the newborns with anemia. Further clinical studies are needed to define the effectiveness of this measurement method in critically ill patients with circulatory disorders."

In a similar study published earlier this year in the Journal of Clinical Neonatology, Drs. Ahmed Jamal and Biju John at Armed Forces Medical College in Pune, India, compared conventional laboratory hemoglobin to SpHb in 100 hemodynamically stable neonatal patients at a tertiary hospital in southern India.² To measure SpHb, they similarly used Radical-7 devices with rainbow^® sensors, but the sensors were placed on the babies’ wrists instead of the foot. Analyzing the paired Lab-Hb and SpHb data with Bland-Altman analysis, the researchers found “a good visual agreement between the Lab-Hb and SpHb values,” and calculated bias ± precision of 0.763 ± 1.349 g/dL. Drs. Jamal and John similarly concluded that SpHb is "an efficacious method of assessing Hb trend among neonates."

In clinical studies with adult patients, continuous monitoring with SpHb as part of blood management programs has been shown to improve outcomes, such as reducing the percentage of patients receiving transfusions,³ reducing the units of red blood cells transfused per patient,^4-5 reducing the time to transfusion,⁶ reducing costs,⁷ and even reducing mortality 30 and 90 days after surgery by 33% and 29%, respectively.⁸ Today, SpHb technology supports clinicians in over 75 countries around the world.⁹

SpHb is not intended to replace laboratory blood testing. Clinical decisions regarding red blood cell transfusions should be based on the clinician’s judgment considering, among other factors, patient condition, continuous SpHb monitoring, and laboratory diagnostic tests using blood samples.

Noninvasive, continuous SpHb for neonatal patients received CE marking in August 2019, and SpHb is now available for patients of all ages in CE marked countries. Noninvasive, continuous SpHb has received FDA clearance for patients > 3 kg but is not currently indicated for patients < 3 kg in the U.S.

Masimo PVi^® Receives FDA Clearance as an Indicator of Fluid Responsiveness on Mechanically Ventilated Patients

Irvine, California – August 14, 2020 - Masimo (NASDAQ: MASI) today announced that PVi^® has received FDA clearance as a continuous, noninvasive, dynamic indicator of fluid responsiveness in select populations of mechanically ventilated adult patients. PVi, or pleth variability index, is a measure of the dynamic changes in perfusion index that occur during the respiratory cycle.

William C. Wilson, MD, MA, Chief Medical Officer at UCI Health, said, "Anesthesiologists and critical care physicians have long recognized the importance of dynamic measures of intravascular volume and fluid responsiveness. Previously this data could only be acquired using an invasive arterial line, and/or additional sophisticated devices. With the Masimo pleth variability index (PVi), one can now obtain this essential data using the pulse oximeter probe and following the continuous readout on the monitor. The PVi technology has undergone rigorous peer-reviewed evaluation, and demonstrated efficacy in determining adequacy of intravascular volume for guiding goal-directed therapy. The recent clearance of the Masimo PVi system will serve as another major breakthrough in promoting patient safety."

Available alongside Masimo SET^® pulse oximetry and rainbow^® Pulse CO-Oximetry on a variety of 2-LED, 4-LED, and 8-LED Masimo sensors, PVi is an index between 0 and 100 that is calculated using a proprietary algorithm based upon the relative variability of the pleth waveform.

Hospital protocols such as Enhanced Recovery After Surgery (ERAS) and Goal-directed Therapy (GDT) recommend fluid management as part of larger initiatives designed to improve patient care and safety. Fluid management protocols look to balance fluids by identifying when patients may be fluid responsive. The utility of PVi as a fluid responsiveness indicator has been demonstrated in more than 100 independent, published studies, including in ERAS and GDT protocols.¹ For example:

• ERAS: In a study of 109 patients undergoing colorectal surgery, researchers found that the implementation of an ERAS protocol which included PVi led to substantial reductions in lengths of stay (from a median of 5 days to 3 days), complication rates (from 30.1% to 14.7%), and costs per patient (from mean cost at 30 days of $20,435 to $13,306 per patient) – in addition to improved patient satisfaction.²
• GDT: In a study of 82 patients undergoing major abdominal surgery, researchers found that GDT with fluid management using PVi reduced the volume of intraoperative fluid infused and reduced intraoperative and postoperative lactate levels.³

In addition, PVi has been used in combination with Masimo's noninvasive, continuous hemoglobin monitoring technology (SpHb^®). In a study published last year involving 18,716 surgical patients at a hospital in Limoges, France, researchers investigated the effects of implementing a hospital-wide protocol for fluid management and blood administration using PVi and SpHb. The researchers found that use of an integrated GDT algorithm using both PVi and SpHb led to earlier transfusion and fewer units of blood transfused, as well as a 33% lower mortality rate 30 days after surgery and a 29% lower mortality rate 90 days after surgery. A year after the study ended, when the hospital did not use PVi and SpHb technology, the mortality rate returned to levels similar to those found before implementation of the GDT protocol.⁴

Stephen Weston, MD, Health Sciences Associate Clinical Professor and Medical Director, Operating Room Support Services, Department of Anesthesia and Perioperative Care at the University of California, San Francisco, said, "At UCSF we display PVi on all of our Masimo pulse oximeters. PVi is a great tool for helping to assess the patient’s fluid status. Having a fluid responsiveness monitor incorporated into something as ubiquitous as pulse oximetry allows us to monitor fluid responsiveness universally. I integrate PVi into my routine sweeps of the hemodynamic data in the operating room, and we’ve rolled out this functionality to the intensive care units as well. Without PVi, I feel that I’m flying a little bit blind."

Joe Kiani, Founder and CEO of Masimo, said, "We are thrilled that at long last we are able to offer clinicians and patients in the U.S. the full benefits of PVi monitoring. Multiple studies have shown how this breakthrough noninvasive indicator of fluid responsiveness can help improve outcomes and reduce costs on mechanically ventilated patients – with no more equipment needed than a software upgrade with most existing Masimo SET^® and rainbow^® platforms and the existing Masimo SET^® sensors that so many top hospitals around the world already use for pulse oximetry."

The accuracy of PVi in predicting fluid responsiveness is variable and influenced by numerous patient, procedure, and device-related factors. PVi measures the variation in the plethysmography amplitude but does not provide measurements of stroke volume or cardiac output. Fluid management decisions should be based on a complete assessment of the patient’s condition and should not be based solely on PVi.

SpHb is not intended to replace laboratory blood testing. Clinical decisions regarding red blood cell transfusions should be based on the clinician’s judgment considering, among other factors, patient condition, continuous SpHb monitoring, and laboratory diagnostic tests using blood samples.

New Blinded Observational Study Shows Greater Depth of Patient Sedation Than Intended During Procedural Colonoscopy

Masimo SedLine^® Brain Function Monitoring with PSi Processed EEG Helped Identify the Oversedations

Irvine, California – August 3, 2020 - Masimo (NASDAQ: MASI) today announced that in a new study published in Anesthesia Research and Practice, researchers used Masimo SedLine^® Brain Function Monitoring to investigate the depth of anesthesia of patients receiving propofol for outpatient colonoscopy, concluding that, "Although providers planned for moderate to deep sedation, processed EEG [electroencephalography] showed patients were under general anesthesia, often with burst suppression. Anesthesiologists and endoscopists may utilize processed EEG to recognize their institutional practice patterns of procedural sedation with propofol and improve upon it."¹

Noting that depth of sedation is "rarely quantified," but that "the spectrum of sedation actually attained in gastrointestinal endoscopy procedures may extend to levels deeper than planned for, thereby exposing patients to…cardiorespiratory risks," Dr. Jamie Bloom and colleagues at Thomas Jefferson University Hospital in Philadelphia sought to understand how frequently patients whose procedures called for moderate to deep sedation using propofol actually experience unintended general anesthesia and burst suppression. To quantify this, they monitored 119 adult patients undergoing outpatient colonoscopies using Masimo SedLine brain function monitoring, including its processed EEG index, the Patient State Index (PSi). PSi provides values that range from 0 to 100, with higher values indicating lesser degrees of sedation (with values from 50 to 25 indicative of general anesthesia, and below 25 for burst suppression). For the study, PSi values correlating to general anesthesia and burst suppression were confirmed by examination of the raw EEG by a neurointensivist and a neurophysiologist.

The researchers found that 118 of the 119 (99.1%) patients attained PSi values of <50, consistent with general anesthesia, and that these patients spent a significantly greater percentage of the procedure with PSi values <50 (53.1% of the time) vs. >50 (42% of the time) (p = 0.001). Of the 118 patients, 33 (27.7%) attained PSi values of <25, consistent with burst suppression. In addition, the researchers found the mean total dose of propofol was significantly correlated with PSi during periods of PSi values <25 (R = 0.406, p = 0.021).

Based on the study results, the researchers concluded, "The depth of sedation achieved with anesthesia administered propofol for colonoscopy spans a continuum. Although providers planned for moderate to deep sedation, processed EEG in this study revealed a substantially greater depth consistent with general anesthesia and even burst suppression."

They continued, "Feedback from devices such as employed in this study to guide the depth of sedation may be considered to not only raise awareness of the physiologic implications of deeper levels of sedation but also to optimize institutional sedation practice. Further research is required to establish the impact on patient outcomes of anesthetic practices resulting in intraprocedural burst suppression."

Patients receiving anesthesia during surgery can be over- or undersedated, both of which carry risks. When under-anesthetized, patients may have awareness during the procedure, which can be traumatic; when they are over-anesthetized, they may have alternating periods of no brain activity as measured by EEG, which is referred to as burst suppression.² Burst suppression has been correlated with increased risk of postoperative delirium,³ which in turn has been shown to increase hospital length of stay and readmission rates, thus increasing costs.⁴ Burst suppression has also been associated with postoperative trauma, dementia, decreased quality of life, additional healthcare costs, and even death.³ In addition to burst suppression, overly deep sedation may result in loss of spontaneous ventilation and impaired cardiovascular function.¹ Oversedation has also been associated with longer time on mechanical ventilation, longer time in the ICU, greater need for radiological evaluation of mental status, and a higher probability of developing brain dysfunction.²

The role of anesthesiologists in keeping patients appropriately sedated, and not over- or under-sedated, is critically important. Masimo SedLine has been shown to help anesthesiologists understand the patient’s sedation state using not only PSi values, but also through interpretation of the raw EEG and the Density Spectral Array that SedLine provides.^4-6 In the current study, researchers showed that even in outpatient procedures, like colonoscopy, there is still a risk of patients being over-anesthetized, leading to burst suppression, which was identified using the PSi available as part of Masimo SedLine brain function monitoring.¹

Masimo Expands the Masimo SafetyNet™ Remote Patient Management Solution with Continuous Body Temperature Measurement

The Radius T°™ Wearable Temperature Sensor Automates Remote Monitoring of Patient Temperature Status

Irvine, California – July 27, 2020 - Masimo (NASDAQ: MASI) today announced a significant expansion to the Masimo SafetyNet™ platform with the introduction of Radius T°™, a wearable, wireless sensor that provides continuous body temperature measurements. By augmenting the already powerful Masimo SafetyNet, which features Radius PPG™ tetherless pulse oximetry, with Radius T°, the remote patient management solution becomes capable of tracking four key vital signs – oxygen saturation, respiration rate, pulse rate, and now temperature – making it an ideal solution for assessing the status of patients with suspected or low-acuity COVID-19, among many other remote patient management uses. Unlike spot-check thermometry solutions, Radius T° measures body temperature continuously, providing remote notifications when a patient’s temperature is outside a clinician-specified range – giving peace of mind to caregiver and patient alike.

Masimo SafetyNet uses a tetherless, wearable single-patient-use Masimo SET^® Measure-through Motion and Low Perfusion™ pulse oximetry sensor to monitor a patient's blood oxygen saturation and pulse rate, as well as respiration rate, perfusion index, and PVi^®. Masimo SafetyNet is designed to help manage the surge in COVID-19 patients while maintaining distance from other patients and providers, allowing hospitals to expand remote patient monitoring into alternative care spaces, including overflow locations, emergency recovery facilities, and home care settings. The telehealth platform combines tetherless pulse oximetry—and now also Radius T° continuous temperature measurement – with a cloud-based remote data capture and surveillance platform accessible from a patient's Android or iOS smartphone or smart device. Monitoring key physiological data provides clinicians with the ability to assess patient status and facilitates awareness of the need for intervention.

Temperature measurement by patients at home typically occurs intermittently, at the prompting of a clinician, and is prone to poor compliance in the collection and reporting of data to healthcare providers in a timely, consistent fashion. A patient taking their temperature at regular or semi-regular intervals may only notice a spike in temperature hours after a fever has begun, or may not even be aware of it, delaying possible clinical intervention. In contrast, Radius T° collects data continuously and seamlessly, recording trend data and automatically notifying remotely when a clinician-specified high temperature threshold is breached, without any action needed on the patient's part. By eliminating inconsistent manual measurements and concerns about patient compliance, while providing continuous insight into changes in body temperature, Radius T° is intended to significantly improve patient status assessment workflows.

Radius Tº is small, light, and comfortable, and is easily applied to the chest. Each shower-proof, single-patient-use sensor lasts up to 8 days and can be worn throughout the day and night, allowing patients to continue normal daily activities while still being monitored. Applied to the skin, Radius T° uses proprietary algorithms to measure the patient’s body temperature, not just external skin temperature, with laboratory accuracy within ±0.1ºC, whereas other thermometry solutions typically have laboratory accuracy within ±0.2ºC. Using Bluetooth^&reg, Radius T° provides this continuous data to the Masimo SafetyNet app on the patient's smartphone and via secure cloud to clinicians back at the hospital, allowing them to track and trend a patient's body temperature, helping them to spot potential deterioration in patient status using the web-based Masimo SafetyNet Clinician Portal.

Joe Kiani, Founder and CEO of Masimo, said, "We're proud to add this noninvasive, continuous, wearable thermometer solution to our growing family of remote patient management solutions. Masimo SafetyNet has already helped clinicians effectively care for countless patients during the pandemic. With the addition of Radius T°, Masimo SafetyNet becomes an even more useful tool for remotely managing patients with COVID-19 and many other health concerns."

Radius T° is indicated for use on patients 5 years and older. Radius T° is not FDA 510(k) cleared; the device is marketed under the FDA's Enforcement Policy for Clinical Electronic Thermometers During COVID-19.

New Study Expands Evidence Demonstrating the Benefits of Critical Congenital Heart Disease (CCHD) Screening Using Masimo SET^® Pulse Oximetry

Neuchatel, Switzerland – July 20, 2020 - Masimo (NASDAQ: MASI) today announced the results of a prospective study published in the International Journal of Neonatal Screening in which researchers in Marrakesh, Morocco conducted the first Moroccan study on critical congenital heart disease (CCHD) screening for newborns using Masimo SET^® pulse oximetry.¹ The authors concluded that "Our results encourage us to strengthen screening for CCHD by adding pulse oximetry to the routine newborn screening panel."

Dr. Slitine and colleagues sought to improve early detection of CCHD in Morocco by studying the feasibility of implementing CCHD screening using pulse oximetry. From March 2019 to January 2020, 8013 asymptomatic newborns at Mother and Child Hospital (part of the Mohammed VI University Hospital of Marrakesh), who were "normal" according to neonatal examination using the current standard, were screened for CCHD in accordance with American Academy of Pediatrics (AAP) guidelines, including pre- and post-ductal oxygen saturation measurement, using Masimo Rad-97^® and Radical-7^® Pulse CO-Oximeters^® with Masimo SET^® pulse oximetry sensors.

The researchers found that, of the 8013 infants screened, 7998 newborns had a negative screen (99.82%) and 15 newborns were screen positive (0.18%). Of those 15, five were later diagnosed with CCHD and five with non-critical CHD; five were false positives (three of which had other underlying conditions). Of the 7998 infants who passed, there was one false negative, an infant who was later diagnosed, at 2 months of age, with coarctation of the aorta.

The researchers noted that the screening test was "easy, simple, reliable, reproducible, acceptable, discriminating, well-accepted by parents and caregivers, and did not involve parental anxiety." They also noted that "Pulse oximetry has a good specificity and sensitivity and thereby fulfills the criteria for screening. Additionally, most of the data in the literature suggest a favorable cost-effectiveness of this technique."

The authors concluded, "Screening for CCHD is a reliable method for the early detection of critical congenital heart disease and even non-cardiac conditions. We think that it will have positive repercussions on infant mortality and morbidity in Morocco. It is an optimal test and it adapts perfectly to our context. We hope to implement it locally and nationally, as consistent with international best practice for newborn screening, to allow for timely detection of the infants born with CCHD in Morocco."

Although the researchers at times use the term pulse oximetry generally, the specific pulse oximetry technology used in this study, as noted, was Masimo SET^®. To date, six other large published CCHD screening studies,^2-7 as well as additional, smaller studies,^8-9 have used Masimo SET^®. Cumulatively, the large studies represent 284,800 infants, which includes the largest CCHD study to date, of 122,738 newborns.² All of these CCHD studies with Masimo SET^® pulse oximetry showed improved screening sensitivity with the use of Masimo SET^® alongside clinical assessment when compared to routine physical exam alone. With its ability to accurately measure through motion and low perfusion, alongside its performance in outcome studies, Masimo SET^® stands out as the established choice of pulse oximetry technology for clinicians and policy makers hoping to implement CCHD screening processes.¹⁰

Masimo Announces UniView: 60™ Digital Charting Solution

UniView: 60 Uses the Power of the Masimo Hospital Automation™ Platform to Improve Clinical Workflows and Hand-off Communication

Irvine, California – July 14, 2020 - Masimo (NASDAQ: MASI) today announced its latest automation and connectivity solution, UniView: 60™. UniView: 60 uses the Masimo Hospital Automation™ platform to aggregate and display pertinent patient information on a digital display just outside each patient's room, allowing clinicians to familiarize themselves with the most relevant details of each patient’s case at the door in 60 seconds or less before they see the patient.

UniView: 60 is intended to improve clinical workflows by helping increase clinicians' awareness of important patient information and advisories – for example, a patient’s risk of falling, environmental warnings, lab results, prescription history, radiological images, monitoring data, and much more – optimally displayed, based on hospital preferences, to help clinicians quickly interpret pertinent information. Unlike paper records and notes, which may display outdated or incorrect information, UniView: 60 utilizes its connections to various hospital information systems to display the most appropriate, up-to-date information directly outside the patient’s room in order to increase clinical efficiency and improve handoff communication between staff.

The hand-off communication process represents an opportunity for significant improvements in patient safety. When clinical information is absent, incomplete, erroneous, or delayed, it can lead to serious patient harm, including medication errors, inaccurate patient plans, delays in transfer to critical care, delays in discharge, and repetitive testing.¹ Adopting a clear and consistent communication strategy, as leading institutions like the University of California, Irvine (UCI) Medical Center have done, has been shown to reduce ineffective hand-offs by nearly 60%.² UniView: 60 is designed to be part of just such a strategy to improve patient safety: by incorporating patient monitoring data and other data and advisories in a standardized fashion from each patient’s full EMR history, UniView: 60 can help to make the hand-off process more consistent and effective.

UniView: 60 is one of many innovations that Masimo is developing to take advantage of the powerful connectivity and data handling architecture of the Masimo Hospital Automation platform, which connects systems across the continuum of care, from bedside monitors and connected third-party devices to electronic medical records (EMRs). Powered by ACE™, advanced translation capabilities, and a robust automation engine, the Masimo Hospital Automation platform helps to ensure interoperability and the free, secure movement of data throughout hospital systems. UniView: 60 takes advantage of this flow of data by optimizing the presentation of pertinent information about each patient's case on an easy-to-interpret, customizable display.

As part of its vision of the hospital of the future and to further its longstanding commitment to patient safety, UCI Medical Center has chosen to deploy UniView: 60 in its new acute care unit. The new unit features the Masimo Root^® Patient Monitoring and Connectivity Platform with Radius-7^® wearable Pulse CO-Oximeters^® at every bedside, Patient SafetyNet™ for supplemental remote monitoring and clinician notification – and at the entrance to each room, UniView: 60 digital chart displays.

"When UCI Health planned its new acute care unit at UCI Medical Center, we wanted a system that allows the entire care team to quickly see and understand a patient's most critical information in a way that enhances patient safety and their relationship with the patient as an individual," said UCI Health CEO Chad T. Lefteris. "Today's clinical environment generates so much data that physicians, nurses, therapists, and other staff can lose sight of the patient. Masimo’s Hospital Automation platform and UniView: 60 meet our objectives by providing the comprehensive solution UCI Health needed to give our patients the best experience possible, while reinforcing our commitment to improving patient outcomes and safety."

Joe Kiani, Founder and CEO of Masimo, said, "We’re delighted to announce UniView: 60 and be able to deploy it at one of our excellent local institutions, the University of California Irvine Medical Center. We're proud to have been able to help UCI as they seek to build the hospital of the future. With UniView: 60, their clinicians are experiencing the power of the Masimo Hospital Automation platform, which connects data and automates processes throughout the hospital, and which is now being harnessed to help ensure that patients get the right care."

Study Investigates Accuracy of Respiration Rate Obtained from Pulse Oximetry on Pediatric Patients Using Masimo RRp^®

Neuchatel, Switzerland – July 06, 2020 - Masimo (NASDAQ: MASI) today announced the results of a study published in Pneumonia in which independent researchers in New Delhi, India, investigated the accuracy of Masimo RRp^® on pediatric patients with the Rad-G™ Pulse Oximeter by comparing it to clinician-determined values while performing routine assessment of children admitted to outpatient and emergency departments.¹ RRp provides respiration rate determined from the photoplethysmograph used in pulse oximetry

Noting the high incidence of childhood pneumonia in many parts of the world, the inclusion of oxygen saturation (SpO₂) and respiratory rate measurement in pneumonia screening guidelines, and the scarcity of medical equipment and variability in medical training in many low-resource settings, Dr. Alwadhi and colleagues sought to determine whether a "multi-modal" pulse oximeter, Masimo Rad-G, could also accurately measure respiration rate – supporting future applications for a more streamlined and reliable approach to pneumonia screening case management. Rad-G uses a single Masimo SET^® pulse oximetry sensor to measure both SpO₂ and RRp, as well as pulse rate (PR), perfusion index (Pi), and pleth variability index (PVi^®).

In this particular study, the researchers used Rad-G, alongside traditional pediatrician assessment, to measure the respiration rate of 97 children (aged 2 to 59 months) admitted to the outpatient and emergency departments at Kalawati Saran Hospital in New Delhi, over 2 weeks. They then analyzed the level of agreement between plethysmography-based respiration rate (RRp) and the clinicians' assessment of respiration rate.

The researchers found that RRp and the control respiration rate measurement method showed "significant strong association (97%)" (p < 0.001), and that "values obtained either from pulse oximeter or by pediatrician (gold standard) are very close to each other." For assessing fast breathing (defined as ≥ 50 breaths per minute (bpm) for infants 2 to 12 months and ≥ 40 bpm for children older than 12 months), RRp had high sensitivity (95%) and specificity (94%), with 95% accuracy. Based on these findings, the authors explained, "The sensitivity analysis, in addition, points to the reliability of the device in correctly identifying fast breathing, a major symptom of the disease [pneumonia], in 95% of the cases." They also noted that Rad-G "allows for significantly integrated results of RR and SpO₂ with high sensitivity and accuracy in health care settings, as well as the possibility of rapid detection."

Joe Kiani, Founder and CEO of Masimo, said, "The opioid epidemic continues to impact millions of people around the world. Unassisted withdrawal from long-term use can be lengthy, extremely unpleasant, and there is a high risk of relapse. Effectively helping to reduce opioid withdrawal symptoms, which is what Bridge has been shown to do, is a critical first step toward successful illicit opioid cessation and treatment. This is the first tool that we are introducing to help with the opioid epidemic. We are committed to doing what we can to help reduce opioid-related deaths."

The researchers concluded, "There is a high degree of agreement between pleth-based RR using a [pulse oximetry device] and physician measured RR, indicating that the former provides reliable and accurate measurement. Current diagnosis and management of pneumonia in primary health care is based on variably trained health providers despite IMCI [Integrated Management for Childhood Illness] guidelines. The use of pulse oximeters, also recommended by the WHO, which can provide reliable measurement, would streamline pneumonia case management in these settings. The current study provides evidence of the reliability of pulse oximeter[s]."

Masimo RRp is CE marked and U.S. FDA 510(k) cleared. Rad-G is currently CE marked and the U.S. FDA 510(k) clearance is pending.

Masimo Announces Bridge™

Drug-free Neurostimulation Device Reduces the Symptoms of Opioid Withdrawal

Irvine, California – June 29, 2020 - Masimo (NASDAQ: MASI) today announced Bridge™, an opioid withdrawal solution that uses neuromodulation to aid in the reduction of symptoms associated with opioid withdrawal. Bridge, which has been granted an FDA De Novo classification, is the first evidence-based, drug-free, non-surgical device of its kind.

Opioid withdrawal is often accompanied by painful, often severe flu-like symptoms lasting for up to two weeks, making voluntary discontinuation by opioid users a long, challenging process. For many patients with opioid-use disorder (OUD), fear of the physical and psychological effects of withdrawal can be a barrier to even attempting to seek treatment. It has been estimated that less than 20% of the more than two million people suffering from OUD in the United States are receiving treatment.¹

By aiding in the reduction of withdrawal symptoms, Bridge can help patients with OUD successfully transition away from opioids into an appropriate treatment program, helping them safely address their disorder. In clinical testing, Bridge was found to reduce opioid withdrawal symptoms within 15-30 minutes and provide continuous relief for as long as it was applied, which can be up to 120 hours per device, allowing opioids to leave the body. In a study of 73 adult OUD patients, it was shown that withdrawal symptoms (such as increases in resting pulse rate, sweating, restlessness, bone or joint aches, tremors, and anxiety) were reduced by 85% after the first hour of using the device and 97% after 5 days of use (measured using the clinical opiate withdrawal scale).²

The solution consists of a wearable, single-patient-use, percutaneous neurostimulator, fitted behind the ear, which applies gentle electrical impulses to branches of the cranial nerves around the ear. These electrical impulses to the cranial nerves have been found to reduce heightened neuron activity,³ which is associated with opioid withdrawal symptoms. Bridge can be easily applied by a healthcare professional in a simple, non-surgical, in-office procedure, and its use doesn’t interfere with normal daily activities such as work or school.

Joe Kiani, Founder and CEO of Masimo, said, "The opioid epidemic continues to impact millions of people around the world. Unassisted withdrawal from long-term use can be lengthy, extremely unpleasant, and there is a high risk of relapse. Effectively helping to reduce opioid withdrawal symptoms, which is what Bridge has been shown to do, is a critical first step toward successful illicit opioid cessation and treatment. This is the first tool that we are introducing to help with the opioid epidemic. We are committed to doing what we can to help reduce opioid-related deaths."

Opioid use (including prescription opioids and heroin) kills many people in the U.S. each year. From 1999 to 2018, opioids were involved in more than 446,000 deaths,⁴ approximately 232,000 of which were the result of overdoses related to prescription opioids.⁵ In 2018, the most recent year for which data is available, approximately 47,000 deaths involved opioids, almost 15,000 of which involved prescription opioids.⁴

Masimo Announces FDA Clearance of Centroid™

Wearable, Wireless Patient Orientation, Activity, and Respiration Sensor Helps Clinicians Monitor Patient Position and Respiration Rate

Irvine, California – June 25, 2020 - Masimo (NASDAQ: MASI) announced today that Centroid™, a wearable, wireless patient orientation, activity, and respiration rate sensor, has received FDA clearance. Centroid helps clinicians monitor patient position to avoid preventable pressure ulcers, and can alert clinicians to sudden movements such as fall-like events. In addition, Centroid detects chest movements to continuously provide respiration rate, assisting clinicians with additional data that may inform care decisions.

Centroid pairs with the Root^® Patient Monitoring and Connectivity Platform using Bluetooth^® to track a patient’s posture, orientation, and activity, providing the ability to monitor patient position and detect changes in position. The data transmitted by Centroid can be displayed in various formats on Root, giving clinicians multiple ways to assess adherence to protocols regarding tissue stress and to tailor care to the specific needs of each patient.

Pressure sores affect nearly 2.5 million patients per year in U.S. hospitals alone, and approximately 60,000 of those patients die as a direct result.¹ Centroid is indicated for the orientation monitoring of patients who may be susceptible to pressure ulcers, by tracking patient movement and activity using an accelerometer and gyroscope. Centroid can identify a patient’s position and orientation to the nearest degree, with alerts based on the duration in a static position to help clinicians adhere to hospital patient turn protocols. Centroid also features customizable alarm zones to help avoid patient positions that could negatively impact recovery time. Unlike simple time-based rotation protocols, Centroid uses the cumulative time spent in each position, as well as existing sore data, to calculate relative risk, displayed on the Root screen using color-coded markers, helping clinicians identify the potential severity of tissue stress for each position—and ultimately, helping to guide clinical decisions about the most appropriate, least risky positions for each patient.

In addition, because Centroid can identify whether a patient is lying down, standing, sitting upright, walking, or may have fallen, it can notify clinicians of a sudden change in position that might provide early warning of a potential fall, by alerting them when clinician-defined movement thresholds are crossed. Its respiration rate performance, validated against manually scored capnogram respiratory measurements, is accurate to within 3 respirations per minute (rpm) in the range of 8 to 35 rpm.

The Centroid single-patient-use sensor is ergonomically designed for application on the chest using flexible, lightweight material for patient comfort, with a gentle adhesive that supports continuous use during daily activities. Each battery-operated sensor is designed to last four days, minimizing the need for frequent replacement.

Joe Kiani, Founder and CEO of Masimo, said, “We are committed to using our expertise in signal processing and sensor design to develop new ways to provide the highest quality, most relevant data to clinicians in the most intuitive, useful formats, and Centroid, coupled with Root’s rich high-resolution display, is a great example of this. We hope that by helping to automate the process of tracking and making decisions about patient position, we can help clinicians reduce the frequency and severity of pressure ulcers, and ultimately improve patient outcomes.”

Masimo's family of continuous and spot-check monitoring Pulse CO-Oximeters^® includes devices designed for use in a variety of clinical and non-clinical scenarios, including tetherless, wearable technology, such as Radius-7^® and Radius PPG™, portable devices like Rad-67™, fingertip pulse oximeters like MightySat^® Rx, and devices available for use both in the hospital and at home, such as Rad-97^®. Masimo hospital automation and connectivity solutions are centered around the Iris^® platform, and include Iris Gateway^®, Patient SafetyNet, Replica™, Halo ION™, UniView™, and Masimo SafetyNet™.
