What is so different about Masimo SET technology? |
 |
Masimo SET® technology is a fundamentally distinct method of acquiring, processing and reporting arterial oxygen saturation and pulse rate. The technology represents a "novel" and "unique" method for calculating the appropriate noise reference in the detected red and infrared signals thus enabling the use of an adaptive noise canceller to remove the noise components. This approach is fundamentally different from a conventional "red over infrared" approach and results in significant performance enhancements unmatched by conventional pulse oximetry systems. A more detailed description of the Masimo SET algorithm is contained in Technical Bulletin #1 Pulse Oximetry Algorithm. |

|
With Masimo SET technology, is the performance enhancement due to the LNOP sensor design or the Masimo SET algorithms? |
|
While there is no specific data to determine the relative contribution between the sensor design and algorithm performance, Masimo feels that approximately 50%-75% of the overall benefit is due to the signal processing algorithms with the remaining 25%-50% attributable to the LNOP sensor design. |

What is the white "bump" on the LNOP sensor? |
|
TThe Masimo LNOP family of sensors are designed to significantly reduce the front end noise contribution from routine patient movements, electromagnetic interference, and ambient light. The white bump on the sensor incorporates the LNOP cavity allowing the photo-detector to be recessed away from the soft tissue of the finger, thereby stabilizing the optical path length between the LED emitters and the photo-detectors during routing patient motion. A more conventional configuration, with the detector tightly attached to the soft tissue of the finger is more susceptible to motion induced "noise" due to a mechanical change in the optical path length. |

Can the Masimo SET system be utilized in high ambient light conditions? |
|
The recessed LNOP photo detector, in combination with Masimo's proprietary signal processing algorithms, is designed to improve system performance in high ambient light conditions such as those encountered in the NICU, OR or even use in direct sunlight. |

|
Does Masimo SET technology provide improved performance in patients with poor perfusion or who are otherwise vasoconstricted? |
|
The Masimo SET system (both signal processing and sensors) is designed to be able to monitor extremely weak peripheral pulses which in many instances are smaller than those capable of being acquired or processed by conventional pulse oximeter systems. This is accomplished through the unique nature of the Masimo SET algorithm and sensor design which is capable of separating the signal from the noise prior to calculating the physiologic measurement.
