Masimo announced the CE Marking of O(3) (TM) regional oximetry for the Root(TM) patient monitoring and connectivity platform. O(3) regional oximetry is a new technology developed by Masimo and uses near-infrared spectroscopy (NIRS) in a Masimo Open Connect (MOC-9(TM)) module with up to two sensors per MOC-9 module. Each sensor contains four light-emitting diodes (LEDs) and two detectors to continuously and simultaneously measure both tissue oxygen saturation (rSO(2)) and arterial blood oxygenation (SpO(2)).

Root allows either one or two O(3) MOC-9 modules to be connected, enabling monitoring with as few as one and as many as four sensors. Regional oximetry, also referred to as tissue oximetry and cerebral oximetry, enables the continuous assessment of the oxygenation of the tissue beneath the sensor. O(3) helps clinicians detect regional hypoxemia that pulse oximetry alone can miss.

In addition, the onboard pulse oximetry capability in O(3) sensors can automate the differential analysis of regional to central oxygen saturation. O(3) monitoring is as simple as applying O(3) regional oximetry sensors to the forehead and connecting the O(3) MOC-9 module to any Root through one of its three MOC-9 ports. Root offers multiple unprecedented, high-impact innovations including: Radical-7(R) with Masimo's breakthrough rainbow(R) and SET(R) measurements; Instantly interpretable, high visibility, intuitive-navigation touchscreen display; MOC-9 flexible measurement expansion with SedLine(R) EEG brain function monitoring and Phasein(TM) capnography, in addition to O3 regional oximetry and future measurements; Iris(TM) for built-in connectivity gateway for standalone devices such as IV pumps, ventilators, hospital beds, and other patient monitors; MyView(TM) for automatic display of parameters, waveforms, and viewing configuration based on the clinician's preference and presence.
