Cerebral perfusion pressure
Cerebral perfusion pressure
The cerebral perfusion pressure (CPP) is defined as being the net pressure gradient causing blood flow to the brain. The CPP is tightly autoregulated to maximise cerebral perfusion. A sharp rise in CPP may result in a rising ICP, a fall in CPP may result in cerebral ischaemia. It may be calculated by the following equation:CPP= Mean arterial pressure - Intra cranial pressure
Following trauma, the CPP has to be carefully controlled and the may require invasive monitoring of the ICP and MAP.
