Outline the physiological factors that influence cerebral blood flow.
The main points expected for a pass were:
• Description of the relationship of CO2; O2; MAP and Cerebral metabolism with cerebral blood flow. The use of graphs, correctly labelled, and associated free text would be an effective means of portraying this information.
• The effect of other factors such as intracranial pressure, cerebral venous pressure, vascular calibre, blood viscosity and regional blood flow differences.
