The Cerebral Circulation

This presentation describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands, and the need for tight water and ion homeostasis. Autoregulation is pronounced in the brain, with myogenic, metabolic, and neurogenic mechanisms contributing to maintain relatively constant blood flow during both increases and decreases...

The cerebral circulation.

THERE are three principal determinants of blood flow across the brain; the volume and pressure of the arterial supply, the resistance to the flow of blood across the brain, and the resistance to venous outflow. Two paired arteries, the carotids and vertebrals, deliver about 750 ml of blood/min to the brain, or about 12% of the cardiac output. In hypovolaemic states a relatively larger portion o...

The cerebral circulation

important in the body because arrest of the circulation for 5 min can cause neuronal death. In order to optimise the delivery of oxygen and metabolic substrates to the brain, anaesthetists need a clear understanding of the anatomy of the cerebral circulation and CSF pathways, the physiology of the cerebral circulation and the effects of anaesthesia, intensive care and other therapeutic interven...
