Web28 mei 2024 · To calculate a mean arterial pressure, double the diastolic blood pressure and add the sum to the systolic blood pressure. Then divide by 3. For example, if a patient’s blood pressure is 83 mm Hg/50 mm Hg, his MAP would be 61 mm Hg. Here are the steps for this calculation: MAP = SBP + 2 (DBP) WebMean arterial pressure can be approximated by the following equation: MAP = ⅓ Systolic blood pressure + ⅔ Diastolic blood pressure Example If systolic pressure is 110 mmHg and diastolic pressure is 80 mmHg, then MAP can be calculated as the following: (1/3 x 110) + (2/3 x 80) = 36.6 + 53.3 = 90 mm Hg. grandland motability
