Mean Arterial Pressure (MAP) Calculator

About Mean Arterial Pressure

Mean Arterial Pressure (MAP) describes the average blood pressure in an individual during a single cardiac cycle. It is a critical parameter for monitoring hemodynamics, particularly in shock or sepsis.

Calculation

Since diastole lasts approximately twice as long as systole, the formula for MAP is:

Where SBP is Systolic Blood Pressure and DBP is Diastolic Blood Pressure.

Clinical Interpretation

• Target MAP: A MAP ≥ 65 mmHg is generally recommended to maintain adequate tissue perfusion in patients with sepsis or septic shock.
• Low MAP: Values < 60 mmHg may result in hypoperfusion and potential ischemia of vital organs (kidneys, brain, heart).
• High MAP: Elevated MAP increases cardiac workload and may indicate hypertension.
