EEG EEG changes generally occur when CBF decreases to 20cc/100g/min [except under isoflurane, where CBF can fall to 8-10cc/100g/min]. Normal brain perfusion is approximately 50 cc/100g/min, and cellular damage occurs at 12cc/100g/min, thus EEG can theoretically warn of impending perfusion deficits. That said, the EEG is a global measure and can be affected by a […]
