Near-infrared Spectroscopy (NIRS), cerebral tissue oxygen extraction (FTOE) is calculated. FTOE reflects cerebral perfusion. Objective: To determine the course of FTOE in the first 48 hours (hrs ...

Cerebral oximeters obtain continuous, noninvasive cerebral oxygenation values [36] using near-infrared spectroscopy (NIRS) technology. A cerebral oximeter setup consists of an oximeter probe ...
