Find your mean arterial pressure from systolic and diastolic blood pressure readings.
Use this free MAP calculator to find your mean arterial pressure from systolic and diastolic blood pressure readings. Assesses organ perfusion and is critical in ICU and emergency settings.

Lower blood pressure value (mmHg)
What is MAP?
Mean Arterial Pressure (MAP) represents the average arterial pressure throughout one cardiac cycle. It's a crucial indicator of organ perfusion, providing more comprehensive information than systolic and diastolic pressures alone.
Normal MAP Range:
A healthy MAP typically ranges between 70-100 mmHg. Values below 60 mmHg may indicate inadequate organ perfusion, while values above 110 mmHg may suggest increased cardiovascular risk.
How to Use This Calculator:
Simply enter your systolic blood pressure (the higher number) and diastolic blood pressure (the lower number), then click "Calculate MAP" to get your mean arterial pressure reading.
Calculation Formula:
MAP = Diastolic Pressure + 1/3 × (Systolic Pressure - Diastolic Pressure)
