Technology Overview The following chapter contains general descriptions about parameters, measurements, and the technology used by Masimo products.
Signal Extraction Technology® (SET®) Masimo Signal Extraction Technology's signal processing differs from that of conventional pulse oximeters. Conventional pulse oximeters assume that arterial blood is the only blood moving (pulsating) in the measurement site. During patient motion, however, the venous blood also moves, causing conventional pulse oximeters to read low values, because they cannot distinguish between the arterial and venous blood movement (sometimes referred to as noise). Masimo SET® pulse oximetry utilizes parallel engines and adaptive filtering. Adaptive filters are powerful because they are able to adapt to the varying physiologic signals and/or noise and separate them by looking at the whole signal and breaking it down to its fundamental components. The Masimo SET® signal processing algorithm, Discrete Saturation Transform® (DST®), in parallel with Fast Saturation Transform (FST®), reliably identifies the noise, isolates it and, using adaptive filters, cancels it. It then reports the true arterial oxygen saturation for display on the monitor.
Masimo SET® DST This figure is for conceptual purposes only.
General Description for Oxygen Saturation (SpO2) Pulse oximetry is governed by the following principles: •
Oxyhemoglobin (oxygenated blood) and deoxyhemoglobin (non-oxygenated blood) differ in their absorption of red and infrared light (spectrophotometry).
•
The amount of arterial blood in tissue changes with your pulse (photoplethysmography). Therefore, the amount of light absorbed by the varying quantities of arterial blood changes as well.

Technology Overview
Successful Monitoring for SpO2, PR and Pi Stability of the SpO2 readings may be a good indicator of signal validity. Although stability is a relative term, experience will provide a good feeling for changes that are artifactual or physiological and the speed, timing, and behavior of each. The stability of the readings over time is affected by the averaging time being used. The longer the averaging time, the more stable the readings tend to become. This is due to a dampened response as the signal is averaged over a longer period of time than during shorter averaging times. However, longer averaging times delay the response of the oximeter and reduce the measured variations of SpO2 and pulse rate.
Functional Oxygen Saturation (SpO2) The MightySat Rx is calibrated to measure and display functional oxygen saturation (SpO2): the amount of oxyhemoglobin expressed as a percentage of the hemoglobin that is available to transport oxygen. Note: Dyshemoglobins are not capable of transporting oxygen, but are recognized as oxygenated hemoglobins by conventional pulse oximetry.
General Description for Perfusion Index (Pi) The Perfusion Index (Pi) is the ratio of the pulsatile blood flow to the non-pulsatile or static blood in peripheral tissue. PI thus represents a noninvasive measure of peripheral perfusion that can be and noninvasively obtained from a pulse oximeter.
General Description for Pulse Rate (PR) Pulse rate (PR), measured in beats per minute (BPM) is based on the optical detection of peripheral flow pulse.
General Description for Pleth Variability Index (PVi) The Pleth Variability Index (PVi) is a measure of the dynamic changes in the Perfusion Index (Pi) that occur during the respiratory cycle. The calculation is accomplished by measuring changes in Pi over a time interval where one or more complete respiratory cycles have occurred. PVi is displayed as a percentage (0-100%). PVi may show changes that reflect physiological factors such as vascular tone, circulating blood volume, and intrathoracic pressure excursions. The utility of PVi has been evaluated in clinical studies [1-11]. Technical and clinical factors that may affect PVi include probe malposition, probe site, patient motion, skin incision, spontaneous breathing activity, lung compliance, open pericardium, use of vasopressors or vasodilators, low perfusion index, subject age, arrhythmias, left or right heart failure, and tidal volume [12-14].

For AndroidTM-powered devices, go to the Google PlayTM store.
• For Apple® devices, go to the App StoreSM. Search and download the “Masimo Professional Health” app. Launch the Masimo Professional Health app. Turn the MightySat Rx Bluetooth On. See Main Menu Options on page 22 of this manual for further instructions. Follow the Masimo Professional Health app on-screen instructions to pair a device. When the Masimo Professional Health app identifies the MightySat Rx, press/select it to pair. Once MightySat Rx is connected to a smart device, the Masimo Professional Health app returns to the Main screen. Note: A connection icon will appear on the MightySat Rx device when a Bluetooth connection has been established. Place MightySat Rx on the patient's finger. Confirm that readings on MightySat Rx and readings displayed on the Masimo Professional Health app are the same without a delay greater than 10 seconds. Note: If the delay is greater than 10 seconds, move the MightySat Rx closer to the smart device and repeat the connection process. Note: To prevent unauthorized connection to the MightySat Rx, turn off the optional Bluetooth LE feature on the MightySat Rx when a connection is not required. CAUTION: When using MightySat Rx (optional Bluetooth version) with a smart device, keep both devices within range of each other (see Specifications on page 31 for details); moving out of range may cause a loss in connection with the smart device.
