What is a normal MAP?

Normal MAP is 70-100 mmHg. A MAP below 65 mmHg indicates inadequate organ perfusion (shock).

Why is MAP more important than systolic BP?

MAP better reflects tissue perfusion because it accounts for the longer diastolic phase of the cardiac cycle.

MAP <65 mmHg in sepsis or shock requires immediate vasopressor therapy (norepinephrine) to maintain perfusion.

Calculate mean arterial pressure (MAP = DBP + 1/3 × (SBP - DBP)) — the average arterial pressure during a cardiac cycle.
