Mean Arterial Pressure (MAP) Calculator
Calculate your Mean Arterial Pressure, a key indicator of overall blood flow and organ perfusion. MAP represents the average pressure in your arteries during one complete cardiac cycle and is used in critical care to guide treatment decisions.
Mean Arterial Pressure is calculated using the formula: MAP = (2 x Diastolic + Systolic) / 3. The reason diastolic pressure is weighted more heavily is that the heart spends approximately two-thirds of each cardiac cycle in diastole (relaxation) and only one-third in systole (contraction). This makes MAP a more accurate representation of the true average pressure driving blood flow to organs.
A MAP of at least 60-65 mmHg is generally considered the minimum necessary for adequate perfusion of vital organs, including the brain, kidneys, and heart. In intensive care settings, maintaining MAP above 65 mmHg is a primary resuscitation target for patients with sepsis, shock, or post-surgical complications. The normal MAP range is approximately 70 to 100 mmHg.
This calculator is for educational purposes only. Blood pressure should be measured by trained professionals using calibrated equipment. A single reading may not be representative. Consult a healthcare provider for blood pressure evaluation, especially if you have concerns about high or low blood pressure.
