Cardiology

Mean Arterial Pressure (MAP)

Average arterial pressure across the cardiac cycle.

Education and reference only. Not a substitute for clinical judgement, local policy or product labelling. Always verify before clinical use. Values are calculated in your browser and never stored.

When to use

Use to estimate perfusion pressure, e.g. in critical care and sepsis where a MAP target (often ≥65 mmHg) guides resuscitation.

Why use

MAP reflects organ perfusion better than systolic pressure alone.

Evidence & references

MAP ≈ (SBP + 2×DBP) / 3.
