Cerebral monitoring by means of oximetry and somatosensory evoked potentials during carotid endarterectomy

Abstract

The results indicate that at least as measured with the INVOS3100A instrument, a decrease in rSO2 of -10 or more or a decrease below an rSO2 of 50 is indicative of cerebral ischemia of sufficient severity to decrease the amplitude of SSEPs.
