WebThe relationship between cerebral blood flow and PaCO2 is nearly linear for PaCO2 >/= 20 mmHg. Thus a cerebral blood flow will decrease 1 ml/100g/min for each mmHg decrease in PaCO2 down to about 20 mmHg. Accordingly, cerebral blood flow will increase 1 ml/100g/min for each 1 mmHg increase in PaCO2. What substance is the most potent … Webthe skull, intracranial pressure (ICP) and the arterial pressure of the blood, mean arterial pressure (MAP). It is important to maintain a constant blood flow. Thus when blood pressure falls, physiological mechanisms attempt to maintain flow to prevent ischaemia. This process is autoregulation and is explained in detail later. Similarly, when blood
