3 Questions
Which of the following is true regarding cerebral autoregulation?
Cerebral autoregulation is believed to be intact between a MAP of 60 to 160 mmHg.
What happens to cerebral blood flow (CBF) when CPP decreases below the lower limit of autoregulation (LLA)?
CBF becomes pressure-dependent, and maximal cerebral vasodilation occurs.
What can happen when CPP exceeds the upper limit of autoregulation?
Cerebral vessels are maximally vasoconstricted, and increased perfusion pressure can cause disruptions such as blood-brain barrier (BBB) disruption, cerebral edema, or cerebral hemorrhage.
