O3®
Regional Oximetry
O3 monitors the regional hemoglobin oxygen saturation of blood (rSO2) in both cerebral and somatic regions for all patient populations. By offering additional insight into changes in tissue oxygen levels, O3 may help clinicians monitor regional oxygenation when pulse oximetry alone may not be fully indicative of oxygen status in a particular region.
The Importance of Cerebral Oximetry
The brain is a vital organ, making it essential to maintain optimal cerebral blood flow in the OR and ICU. When peripheral pulse oximetry alone may not fully reflect brain oxygen levels, O3 offers clinicians deeper insight into oxygen status, which may help improve patient outcomes.
Comprehensive Display
O3 connects to the Root patient monitoring platform, displaying the following parameters to provide key insights into a patient’s regional oxygenation status.
Available for All Patient Populations
With their flexible design, O3 sensors easily conform to and allow for ergonomic application on foreheads of all sizes.
Infant/Neonatal
3% ARMS* trending accuracy specification
Pediatric
5% ARMS absolute accuracy and 3% ARMS trending accuracy specifications
Adult
4% ARMS absolute accuracy and 3% ARMS trending accuracy specifications

A Total Monitoring Solution via a Multimodal Platform
Expand Visibility in the OR and ICU
Use Root with O3 alone or in combination with other modalities to see a more complete picture of the brain or other tissue of interest, and make more informed assessments to help improve patient outcomes.
Harness the Power of Root
O3 connects seamlessly to the versatile Root Patient Monitoring and Connectivity Platform, which features a customizable, easy-to-interpret display with multiple views of monitoring data for expanded visibility in the OR and ICU.
SedLine Brain Function Monitoring
O3 can be used simultaneously with SedLine, which monitors the state of the brain under anesthesia, to provide a more complete picture of the brain.
Integrated Perioperative Monitoring
Via Root, O3 and SedLine can be used in tandem with Masimo rainbow® parameters like noninvasive, continuous hemoglobin (SpHb®) giving perioperative clinicians the real-time data they need while performing critical care.
