Mean arterial pressure (MAP) Calculator

Systolic BP: mm Hg
Diastolic BP: mm Hg


Equation:  MAP = [(2 x diastolic)+systolic] / 3

Diastole counts twice as much as systole because 2/3 of the cardiac cycle is spent in diastole. An MAP of about 60 is necessary to perfuse coronary arteries, brain, kidneys.
Usual range:  70-110
