Mean Arterial Pressure (MAP)

Calculate MAP from systolic and diastolic blood pressure. MAP = DBP + 1/3 × (SBP – DBP).

Systolic BP

mm Hg

70 – 200

Diastolic BP

mm Hg

40 – 120

Enter SBP and DBP, then tap “Calculate MAP”

MAP = (2 × DBP + SBP) / 3 · Target MAP ≥ 65 mm Hg (adults) ; for children, use age-specific norms.

MAP is a key indicator of perfusion. This is a guide — always correlate clinically.
