Chapter 5- O3 Regional Oximetry
The O3 system is a patient-connected, noninvasive oximeter designed to
continuously measure and monitor regional hemoglobin oxygen saturation in the
tissue (rSO2), including cerebral tissue. It can be used in any hospital and hospital-
type facility where rSO2 measurements might improve patient outcomes.
The Masimo O3 Regional Oximeter and Sensors are indicated for the continuous
noninvasive monitoring of regional hemoglobin oxygen saturation of blood (rSO2)
in the tissue below the sensor in hospital and hospital-type facilities. See the O3
Operator's Manual for more information.
