What is the normal range for cerebral perfusion pressure (CPP)?

The normal range for cerebral perfusion pressure (CPP) is typically considered to fall between 70-90 mm Hg. CPP is a critical parameter that indicates the pressure gradient driving blood flow to the brain. Maintaining an adequate CPP is vital for ensuring sufficient oxygen and nutrient delivery to the brain tissue, which is particularly crucial in critical care settings.

When CPP is within the range of 70-90 mm Hg, it supports optimal cerebral blood flow, helping to prevent ischemia and ensure healthy neurological function. Values below this range can lead to inadequate perfusion, increasing the risk of brain injury, while values significantly above may cause complications such as increased intracranial pressure or hemorrhage.

Therefore, knowing that 70-90 mm Hg is the standard range helps healthcare providers manage and monitor patients effectively, especially those with conditions that might compromise cerebral blood flow.
