Mean Arterial Pressure (MAP) Calculator
Calculate mean arterial pressure and pulse pressure from systolic and diastolic blood pressure readings.
How to Use the Mean Arterial Pressure (MAP) Calculator
- Enter systolic BP in mmHg.
- Enter diastolic BP in mmHg.
- Click Calculate to see MAP, pulse pressure, and interpretation.
Cas d'utilisation
- •Assessing hemodynamic stability in critically ill patients.
- •Targeting vasopressor support during shock.
- •Routine blood pressure interpretation.
Formule
MAP = DBP + (SBP − DBP)/3. Pulse pressure = SBP − DBP. MAP below 65 mmHg is associated with organ hypoperfusion.
Questions fréquemment posées
Why is MAP important?
MAP represents the average arterial pressure over a cardiac cycle and is used to assess organ perfusion. Critical care guidelines target MAP ≥ 65 mmHg to maintain adequate tissue oxygenation.
Why divide pulse pressure by 3?
The formula MAP = DBP + (SBP − DBP)/3 reflects that the heart spends roughly two-thirds of each cycle in diastole, so diastolic pressure dominates the time-averaged value.
