Cerebral autoregulation can also be assessed using the autoregulation index (ARI), a dimensionless index ranging from 0 to 9, for which a response of FV to a hypothetical impulse change in ABP is estimated using transfer function analysis of spontaneous fluctuations in ABP and FV.
What is an example of autoregulation?
Autoregulation is a manifestation of local blood flow regulation. ... For example, if perfusion pressure is decreased to an organ (e.g., by partially occluding the arterial supply to the organ), blood flow initially falls, then returns toward normal levels over the next few minutes.
What is autoregulation in the body?
Autoregulation refers to the intrinsic ability of an organ to maintain blood flow at a nearly constant rate despite changes in arterial perfusion pressure.
