WebAutoregulation of Cerebral Blood Flow. Cerebral autoregulation is the process by which cerebral blood flow is maintained at a stable level over a wide range in blood pressure. 31 If blood pressure rises to levels beyond the autoregulatory range, particularly if the rise in blood pressure is rapid, cerebral blood flow and hydrostatic capillary ... WebCerebral autoregulation (CA) maintains relatively constant cerebral blood flow despite perfusion pressure change. The study of the CA phenomenon was difficult when using invasive methods for assessing changes in cerebral blood flow and perfusion pressure, which are not applicable in clinical practice [ 1 ].
