cerebral blood flow


Also found in: Acronyms, Wikipedia.

cerebral blood flow

a measurement or parameter of the blood's ability to perfuse brain tissue adequately. Thought to be as significant or more significant than cerebral perfusion pressure and intracranial pressure to assist ability of brain cells to survive insult. It depends on multiple factors, including brain vasomotor activity.

cerebral blood flow

1 the blood supply to the brain in a given period of time.
2 the circulation of blood through the vascular system of the brain.
