Summary
In the adult, cerebral blood flow (CBF) is typically 15% of the resting cardiac output (approximately 750 mL/min). CBF is commonly expressed in terms of the weight of brain parenchyma – normal CBF is 50 mL/100 g brain tissue/min. It is determined by the ratio of the cerebral perfusion pressure (CPP) and cerebral vascular resistance (CVR).
