Volume Measurement of Cerebral Blood Flow: Assessment of Cerebral Circulatory Arrest

Abstract

Early confirmation of cerebral circulatory arrest is of decisive importance if the patient is a potential organ donor. CBF volume measurement allows confirming the arrest of cerebral circulation even in patients without a patent acoustic bone window for TCCD. Because the critical lower threshold for survival appears to lie at 200 ml/min, bedside monitoring of CBF volume in neurointensive care patients may indicate a therapeutic window before irreversible circulatory arrest occurs.
