MAP, or mean arterial pressure, is defined as the average pressure in a patient's arteries during one cardiac cycle. It is considered a better indicator of perfusion to vital organs than systolic blood pressure (SBP).

What is mean arterial pressure equal to?

Mean arterial pressure

Mean arterial pressure (MAP) ^[1,2] = [systolic blood pressure + (2 X diastolic blood pressure)] / 3. The reference range is 70-100 mm Hg.

Does mean arterial pressure change?

Mean arterial blood pressure normally decreases by less than 1 mmHg between the ascending aorta and a peripheral artery such as the cerebral and renal arteries.
