WebJul 1, 2015 · Cerebral autoregulation is a homeostatic process that regulates and maintains cerebral blood flow (CBF) constant and matched to cerebral metabolic demand across a range of blood pressures. It is affected by: PaCO2: increased PaCO 2 leads to increased CBF. PaO2: PaO 2 falling below 50 mmHg leads to exponentially increased CBF. nursing leadership management articles

WebMyogenic Regulation (Autoregulation) of Cerebral Blood Flow Autoregulation refers to the capacity of the cerebral circulation to alter vascular resistance to maintain a relatively constant CBF over a range of mean arterial pressure (MAP). WebCerebral Autoregulation. Cerebral autoregulation is a mechanism that maintains a stable CBF for a given cerebral metabolic rate in spite of fluctuation in cerebral perfusion pressure (CPP).6 It is visualized as a correlation plot of CBF (axis of ordinate) against CPP (axis of abscissas).
