Mean Arterial Pressure Calculator: MAP from Bloo...
Calculate Mean Arterial Pressure (MAP) from systolic and diastolic blood pressure readings. Understand what MAP means for organ perfusion and cardiovascular health.
What is Mean Arterial Pressure (MAP)?
Mean Arterial Pressure (MAP) is the average arterial pressure throughout one complete cardiac cycle. It is more clinically meaningful than systolic blood pressure alone because it reflects the true perfusion pressure driving blood to vital organs. A normal MAP in healthy adults is 70–100 mmHg.

📐 Formula
MAP = DBP + ⅓(SBP − DBP)
SBP = Systolic Blood Pressure, DBP = Diastolic Blood Pressure. ⅓ reflects that diastole occupies ~2/3 of the cardiac cycle.
📝 Worked Example
Blood pressure = 120/80 mmHg:
MAP = 80 + ⅓(120 − 80) = 80 + 13.3 = 93.3 mmHg
This is within the normal range (70–100 mmHg).
📝 How to Use the Calculator
❓ FAQ
Why is MAP clinically important?
MAP < 65 mmHg is a clinical threshold for shock and is the primary target in sepsis management protocols.
Is MAP the same as average BP?
Not exactly — it is a weighted average reflecting the time spent in systole vs diastole, which is why diastolic pressure is weighted more.
