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:

[tex]CPP=52mm \ Hg[/tex]

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 [tex]70mm \ Hg[/tex]. MAP is obtained using the formula:-

[tex]MAP=\frac{(diastolic \ blood \ pressure\times2)+\ systolic \ blood \ pressure)}{3}\\\\MAP=\frac{2\times60+90}{3}\\\\MAP=70mm \ Hg\\CPP=MAP-ICP\\CPP=70-18\\CPP=52mm \ Hg[/tex]
