SedLine brain function monitoring helps clinicians monitor the state of the brain under anaesthesia with bilateral data acquisition and processing of EEG signals that may help clinicians with anaesthetic management. O3 regional oximetry helps clinicians monitor cerebral oxygenation in situations where pulse oximetry alone may not be fully indicative of the oxygen in the brain.
Each O3 sensor contains a common emitter and two detectors at different distances relative to the emitter.
Schematic of an example of a regional oximeter sensor measuring deep tissue oxygenation.
The detectors are often known as the shallow detector, which is closer to the emitter and receives the optical signal that travels through relatively superficial (shallow) tissue; and the deep detector, which is farther from the emitter and receives the optical signal that travels deeper into tissue, in addition to passing through superficial layers. Deep tissue oxygenation is calculated by subtracting the effects of shallow tissue from those of deep tissue by manipulating the signals received by the two detectors on each sensor.
