Masimo Rad-57 Rainbow SET Pulse Oximeter

The Power of Masimo’s Breakthrough Measurements in a Patient-worn Monitor

With breakthrough rainbow SET® technology and wireless communication, Radius-7 is designed to allow patient mobility along with continuous monitoring, enabling early identification of clinical deterioration.

Breakthrough rainbow SET® measurements

  • > Oxygen saturation (SpO2) and pulse rate monitoring with Masimo SET® Measure-through Motion and Low Perfusion pulse oximetry for reliable detection of desaturation and accurate pulse rate while dramatically reducing false alarms1, 2
  • > Respiration rate monitoring through either rainbow Acoustic Monitoring for acoustic respiration rate (RRa®) or through the plethysmograph waveform (RRp) to identify respiratory depression or tachypnea3
  • > Noninvasive and continuous haemoglobin (SpHb®) monitoring with rainbow® Pulse CO-Oximetry may help clinicians detect bleeding earlier, avoid
    unnecessary blood draws, and optimise
    transfusion decisions

Small, lightweight, and wearable for untethered monitoring and ambulation

  • > Designed to promote greater patient comfort and independence

  • > Reduces the need for nurses to disconnect the monitor each time the patient gets out of bed

Standard wireless communication

  • > Short-range communication to Root® with secured Bluetooth
  • > Upgradeable to WiFi* for direct communication throughout the hospital to the Patient SafetyNet™** remote monitoring system


  • > Intuitive touch-pad navigation and trend views facilitate on-the-spot assessment of patient status
  • > Configurable display shut-off minimises patient distraction and supports privacy while ambulating
  • > Alarms through Root when in range or directly on Radius-7 when out of range
  • > Two “hot-swappable,” rechargeable modules (one on Radius-7, one charging in Root) minimise monitoring interruption
  • >12-hour battery life facilitates just one module exchange per shift
  • > Single-patient use armband minimises cross-contamination risk while ensuring patient comfort
  • > Seamless module pairing with Root to facilitate nursing workflows

Each Radius-7 comes with two rechargeable, “hot-swappable” modules.
