Calculating Cerebral Perfusion Pressure. Brain is not being perfused and as the map starts to equal the icp the cpp will fall. Subtract the cvp from the map to get the cerebral perfusion pressure. Cpp 92 14 cpp 78 mmhg interpretation. Following the legend the formulas are.
Map 130 2 73 3 map 130 146 3 map 276 3 map 92 mmhg substitute the icp and map into the cpp formula. Map mean arterial pressure. Calculate the map using the formula map sbp 2 dbp 3. Dilation and constriction of the intracranial arterial system maintains appropriate cpp. Cerebral perfusion pressure measures blood flow to the brain. Cpp 92 14 cpp 78 mmhg interpretation.
For example a patient with a cvp of 7 mm h2o and a blood pressure of 120 80 will have a cpp of 93 7 86.
Knowing how to calculate cerebral perfusion pressure is a useful tool when managing patients with brain trauma and other neurological disorders. Cerebral perfusion pressure cpp is the net pressure gradient of blood flow in the brain and is maintained by a process known as autoregulation. 144 108 252.
