This tool uses the common resting approximation from a cuff reading. It is most useful as a quick estimate when the reading was taken carefully and the heart rhythm is steady.

This mean arterial pressure calculator provides a general estimate only and is not medical advice. It should not be used by itself to diagnose illness, judge perfusion, or decide whether a symptom or blood pressure reading is an emergency. For personal interpretation or urgent symptoms, speak with a qualified healthcare professional right away.
