To preserve cerebral perfusion of a patient with an elevated intracranial pressure (ICP), which cerebral perfusion pressure (CPP) would the nurse maintain when suctioning the patient?

80 mm Hg

20 mm Hg

40 mm Hg

60 mm HG

Answer and Explanation

The Correct Answer is A

A.   Cerebral perfusion pressure (CPP) is crucial for maintaining adequate blood flow to the brain. A CPP of 80 mm Hg is typically considered the lower limit for preserving cerebral perfusion, particularly in patients with elevated ICP.
B.   20 mm Hg is too low and would indicate inadequate perfusion, which could result in brain ischemia.
C.   40 mm Hg is too low for optimal cerebral perfusion in critically ill patients with elevated ICP.
D.   60 mm Hg is also too low for optimal cerebral perfusion in critically ill patients with elevated ICP.
