3 Απρ 2023 · Cerebral perfusion pressure (CPP) is the net pressure gradient that drives oxygen delivery to cerebral tissue. It is the difference between the mean arterial pressure (MAP) and the intracranial pressure (ICP), measured in millimeters of mercury (mm Hg).
7 Ιουλ 2024 · OVERVIEW. Cerebral Perfusion Pressure (CPP) = MAP – ICP or CVP (whichever is highest) Cerebral Blood Flow (CBF) = CPP/CVR [CVR = cerebral vascular resistance] Brain Trauma Foundation (BTF) guidelines support a target CPP of 50-70 mmHg in patients with severe Traumatic Brain Injury. AUTOREGULATION.
17 Φεβ 2020 · Cerebral perfusion pressure (CPP) is the amount of pressure needed to maintain blood flow to the brain. CPP is regulated by two balanced opposing forces: Mean arterial pressure (MAP) is the driving force that pushes blood into the brain. Intracranial pressure (ICP) is the force that keeps blood out.
Measurement of intracranial pressure (ICP) and mean arterial pressure (MAP) is used to derive cerebral perfusion pressure (CPP) and to guide targeted therapy of acute brain injury (ABI) during neurointensive care.

28 Νοε 2013 · Measurement of intracranial pressure (ICP) and mean arterial pressure (MAP) is used to derive cerebral perfusion pressure (CPP) and to guide targeted therapy of acute brain injury (ABI) during neurointensive care. Here we provide a narrative review of the evidence for ICP monitoring, CPP estimation, and ICP/CPP-guided therapy after ABI.
Under normal circumstances a MAP between 60 and 160 mmHg and ICP about 10 mmHg (CPP of 50-150 mmHg) sufficient blood flow can be maintained with autoregulation.
