Calculate MAP from systolic and diastolic blood pressure readings. Get instant clinical interpretation of the result to assess perfusion status.
Mean Arterial Pressure
93.3 mmHg
Status
Normal
Between 70–100 mmHg — adequate perfusion pressure for most patients.
Low: <60 | Borderline: 60–70 | Normal: 70–100 | High: >100 mmHg
Systolic
120 mmHg
MAP
93.3 mmHg
Diastolic
80 mmHg
Pulse Pressure
40 mmHg
Normal: Optimal perfusion pressure for all organs.
Autoregulates between MAP 60-150 mmHg
Require MAP > 65 for adequate filtration
Coronary perfusion depends on diastolic pressure
Susceptible to ischemia at low pressures
Mean Arterial Pressure represents the average blood pressure throughout one complete cardiac cycle. Since the heart spends roughly twice as long in diastole as in systole, the formula weights diastolic pressure more heavily: MAP = (SBP + 2 × DBP) / 3. This value is critical for assessing whether a patient has adequate blood flow to perfuse vital organs, and is frequently used as a hemodynamic target in critical care.
Mean Arterial Pressure is the average pressure in the arteries during one cardiac cycle. It reflects perfusion pressure to vital organs and is calculated as MAP = (SBP + 2 × DBP) / 3, where SBP is systolic blood pressure and DBP is diastolic blood pressure.
MAP is considered a better indicator of organ perfusion than systolic or diastolic pressure alone. A MAP of at least 65 mmHg is generally needed to adequately perfuse the brain, kidneys, and other vital organs. It is a critical parameter monitored in ICU and emergency settings.
A normal MAP typically falls between 70 and 100 mmHg. A MAP below 60 mmHg may indicate inadequate perfusion and can lead to organ damage. A MAP above 100 mmHg may suggest hypertension that warrants assessment and potential treatment.
