Mean Arterial Pressure (MAP) — Direct Answers

Direct answers for the most-searched MAP / blood pressure queries:

What is MAP (Mean Arterial Pressure)?

The average pressure in a person's arteries during one cardiac cycle. Normal MAP is 70–100 mmHg; below 65 may indicate poor perfusion.

How is MAP calculated?

MAP = (2 × Diastolic + Systolic) / 3. Equivalently: MAP = Diastolic + ⅓(Systolic − Diastolic).

MAP for BP 120/80?

93 mmHg. (2 × 80 + 120) / 3 = 93.

MAP for BP 90/60?

70 mmHg. Normal but on the low end.

What MAP is dangerous?

< 65 mmHg may compromise organ perfusion. > 100 may indicate hypertension. > 130 is a hypertensive crisis.

Why does MAP matter more than systolic?

MAP reflects perfusion pressure — the driving force for blood flow to organs. Used in ICU and sepsis protocols.

Quick Answer: MAP from Blood Pressure

Mean arterial pressure (MAP) = DBP + ⅓ × (SBP − DBP). Normal MAP is 70-100 mmHg; below 65 indicates poor organ perfusion. Use the calculator above for personalized numbers:

MAP = DBP + ⅓ × pulse pressure. Normal MAP range: 70-100 mmHg. AHA / ACC 2017 guidelines classify blood pressure as above. MAP < 65 mmHg is associated with organ hypoperfusion in critical care.
