A decrease in cerebral perfusion pressure is related to which of the following changes?
A) Increase in arterial blood pressure
B) Increase in cerebral blood flow
C) Increase in intracranial pressure
D) Cerebral artery vasodilation

Question

Quizplus · Accepted Answer

A decrease in cerebral perfusion pressure indicates a reduction in the pressure gradient between the arterial blood pressure and the intracranial pressure, which can occur due to an increase in intracranial pressure. An increase in arterial blood pressure or cerebral blood flow would result in an increase in cerebral perfusion pressure. Cerebral artery vasodilation may or may not affect cerebral perfusion pressure, depending on its contribution to cerebral blood flow and changes in intracranial pressure.
