Mean Arterial Pressure (MAP) Calculator
Mean arterial pressure estimates the average pressure in your arteries across a heartbeat. It is a useful single number for organ perfusion.

FAQs
What is mean arterial pressure?
Mean arterial pressure is the average pressure in your arteries during one cardiac cycle. It matters because it drives blood flow to your organs. A common estimate is MAP equals systolic pressure plus twice the diastolic pressure, all divided by three.
What is a normal MAP?
A MAP of roughly 70 to 100 mmHg is generally considered healthy. Values below about 60 mmHg may not perfuse organs well, while persistently high values are worth discussing with your physician.
Is this a substitute for a blood pressure reading?
No. MAP is calculated from a blood pressure reading you already have. Use an accurate, properly measured systolic and diastolic value for a meaningful result.
