Mean Arterial Pressure Calculator
Estimate mean arterial pressure and pulse pressure from systolic and diastolic blood pressure.
Formula
MAP = (SBP + 2*DBP)/3; pulse pressure = SBP - DBP.
About the Mean Arterial Pressure Calculator
Estimate mean arterial pressure and pulse pressure from systolic and diastolic blood pressure.
How the Mean Arterial Pressure Calculator Works
The resting-heart-rate approximation weights diastolic pressure twice and reports pulse pressure separately.
Formula
MAP = (SBP + 2*DBP)/3; pulse pressure = SBP - DBP.
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.
Required Inputs

Accuracy and Limitations
The formula is an approximation and may be inaccurate at very high heart rates or unusual waveforms. It does not replace direct monitoring or clinical evaluation.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
