Mean Arterial Pressure Calculator

MAP is a critical value in assessing adequate blood flow to vital organs, especially in patients with sepsis, shock, or head injury. Typically, a MAP of at least 60 mmHg is required to maintain perfusion to organs. For example, a patient with SBP of 120 mmHg and DBP of 80 mmHg would have a MAP of (120 + 2×80)/3 = 93.3 mmHg. This tool simplifies the manual calculation process and helps in making quick clinical decisions.

Mean Arterial Pressure Formula

Formula
$$MAP = \frac{SBP + 2 \times DBP}{3}$$

Where:

  • $$SBP$$ = Systolic Blood Pressure (mmHg)
  • $$DBP$$ = Diastolic Blood Pressure (mmHg)

The formula gives more weight to diastolic pressure because the heart spends more time in diastole during the cardiac cycle.
