Question

A client with a head injury is being monitored for increased intracranial pressure (ICP). The client's blood pressure is 90/60 mm Hg and the ICP is 18 mm Hg; therefore their cerebral perfusion pressure (CPP) is

Answer 1

`CPP=52mm \ Hg`

Step-by-step explanation:

Cerebral Perfusion Pressure is obtained by subtracting IntraCranial Pressure(ICP) from the Mean Arterial Pressure(MAP). Adequate cerebral perfusion requires a minimum goal of
`70mm \ Hg`. MAP is obtained using the formula:-

`MAP=((diastolic \ blood \ pressure*2)+\ systolic \ blood \ pressure))/(3)\\\\MAP=(2*60+90)/(3)\\\\MAP=70mm \ Hg\\CPP=MAP-ICP\\CPP=70-18\\CPP=52mm \ Hg`
