You have admitted a patient to the Neurolog Intensive Care Unit with a brainstem herniation. The patient is now exhibiting an altered level of consciousness
The nurse has determined that the patient's mean arterial pressure (MAP) is 60 with an intracranial pressure (ICP) reading of 5 mm Hg. The nurse would be correct in determining the cerebral perfusion pressure (CPP) as which of the following values?
A) Normal
B) High
C) Low
D) Compensating
Ans: C
Feedback: The cerebral perfusion pressure (CPP) is 55 mm Hg, which is considered low. The normal CPP is 70 to 100 mm Hg. Patients with a CPP of less than 50 mm Hg experience irreversible neurologic damage. A lower than normal CPP indicates that the cardiac output is insufficient to maintain adequate cerebral perfusion.
