Map Mean Arterial Pressure

The definition of mean arterial pressure (map) is the average arterial pressure throughout one cardiac cycle, systole, and diastole. Where dp is the diastolic pressure and pp is the pulse pressure (the difference between systolic and diastolic). The mean arterial pressure (map) can tell healthcare providers how well your blood flow is and if your tissues are getting enough blood.

Mean arterial pressures that deviate from this range for prolonged periods of time can have drastic negative effects on the body. Prolonged hypotension, defined as a map of less than 60 to 65 mm hg, is associated with poor outcome 1,2]. The definition of mean arterial pressure (map) is the average arterial pressure throughout one cardiac cycle, systole, and diastole.

High map can cause stress on the heart because it has to work harder than normal to push against the elevated pressure in the vessels.

Mean arterial pressure is the pressure in your arteries during one cardiac cycle, and it tells us how well the vital organs (like the renal system, brain etc.) are being perfused. This representative diagram is loosely borrowed from gedde's handbook of blood pressure measurement. Mean arterial pressures that deviate from this range for prolonged periods of time can have drastic negative effects on the body. A single cardiac cycle is taken into consideration for the calculation of mean arterial pressure.
