Question: 1 / 400

According to current guidelines, what is the ideal range for cerebral perfusion pressure (CPP)?

15 to 25 mm Hg

30 to 40 mm Hg

45 to 60 mm Hg

50 to 70 mm Hg

The ideal range for cerebral perfusion pressure (CPP) is considered to be between 50 to 70 mm Hg. This range is crucial for ensuring adequate blood flow to the brain, which is essential for maintaining neuronal function and preventing ischemic damage. A CPP within this range helps to assure that the cerebral blood flow (CBF) is sufficient to meet metabolic demands, especially in critically ill patients or those with head injuries. Maintaining CPP in this range is particularly important because values below 50 mm Hg can lead to inadequate perfusion, causing cellular injury and potential neurological deficits. Values above 70 mm Hg, while not explicitly harmful, may indicate excessive fluid administration or increased intracranial pressure (ICP), which can also be detrimental to cerebral health. Thus, keeping CPP within the 50 to 70 mm Hg range is an essential component of neurological care in flight and emergency settings.
