Calculate your Mean Arterial Pressure (MAP) from systolic and diastolic blood pressure readings. MAP represents the average blood pressure during a single cardiac cycle.
Blood Pressure
Results
MAP = DBP + ⅓(SBP − DBP)
Or: (SBP + 2×DBP) ÷ 3
Normal MAP: 70–100 mmHg
Minimum for organ perfusion: 60 mmHg
The MAP blood pressure calculator computes your Mean Arterial Pressure, which represents the average pressure in your arteries during one complete cardiac cycle. MAP is clinically important because it determines whether there is sufficient blood flow to perfuse vital organs. A MAP of at least 60 mmHg is needed for adequate organ perfusion.
A normal MAP ranges from 70 to 100 mmHg. MAP below 60 mmHg may indicate insufficient blood flow to organs (hypoperfusion), while MAP above 100 mmHg may indicate hypertension. In critical care, maintaining MAP above 65 mmHg is a common resuscitation target.
MAP is considered a better indicator of tissue perfusion than systolic or diastolic pressure alone. It accounts for the fact that the heart spends more time in diastole than systole. Clinicians use MAP to guide treatment of shock, sepsis, and during surgery.
