Mean Arterial Pressure
MAP from systolic and diastolic blood pressure.
What this calculator does
This tool calculates mean arterial pressure (MAP) from your systolic and diastolic blood pressure. MAP is an average pressure during the heart cycle and is used in some clinical settings.
What your result means
MAP is one way to summarize blood pressure. Your doctor uses it when relevant (e.g. in critical care or research). What is “normal” or concerning depends on your situation; your provider can explain.
This is not medical advice. A healthcare provider should interpret results in your context.
