Mean Arterial Pressure: Why Clinicians Use It

MAP shows whether organs get enough blood flow.

· 2 min read

What MAP is

Mean arterial pressure is the average pressure in arteries over a cardiac cycle. It is estimated as diastolic plus one third of the pulse pressure.

Why it matters

Organs such as kidneys and brain need a MAP of at least about 65 mmHg. Doctors in hospitals watch it in sepsis and shock.

At home

Home users rarely need MAP, but it helps to understand why a very low reading with dizziness needs attention.
