Cerebral Blood Flow Monitoring

For an organ measuring roughly 2% of the total body weight, the brain needs an average of 50 mL blood for every 100 g of brain tissue per minute, accounting for 15% of the total cardiac output. The need for a constant blood supply to maintain the normal function and structure of the brain owing to its high metabolic rate renders cerebral perfusion an extremely crucial cog in brain homeostasis. The brain’s inability to store oxygen or glucose makes the role of constant cerebral blood flow (CBF) all the more vital.
