Mean Arterial Pressure Calculator

Average Arterial Pressure

Mean arterial pressure, or MAP, estimates the average pressure in the arteries during one cardiac cycle.

Method: The common cuff-based estimate adds one third of pulse pressure to diastolic pressure: MAP = DBP + (SBP - DBP) / 3.

Understanding Mean Arterial Pressure

1. What This Calculator Measures

Mean arterial pressure estimates average arterial pressure across a heartbeat cycle.

2. How the Calculation Works

The calculator adds one third of pulse pressure to diastolic blood pressure.

3. Formula or Rule Used

MAP = DBP + (SBP - DBP) / 3.
