Symptoms of late stages of intracranial hypertension include
a. decreased perfusion of cerebral tissue.
b. widening pulse pressure values.
c. increased perfusion pressure across the blood–brain barrier.
d. decreased intracranial pressure.
B
Attention must also be paid to the pulse pressure because widening of this value may occur in the late stages of intracranial hypertension. With the loss of autoregulation as blood pressure increases, cerebral blood flow (CBF) and cerebral blood volume increase and intracranial pressure (ICP) therefore increases. The mean arterial pressure must be maintained at a level sufficient to produce adequate CBF in the presence of elevated ICP.
