Correlation of Noninvasive Cerebral Oximetry with Cerebral Perfusion in the Severe Head Injured Patient: A Pilot Study

Abstract

In this pilot study, StCO2 correlated significantly with CPP. A StCO2 > or = 75 suggests that CPP is adequate, while < 55 suggests an inadequate CPP. Although these results should be confirmed in a larger study, StCO2 may serve as a noninvasive measurement of cerebral perfusion in the patient with a TBI or, at the very least, a sensitive indicator for the need to begin monitoring the ICP.
