Mean arterial pressure is closer to systolic blood pressure than diastolic blood pressure Mean arterial pressure is closer to sy
Ganezh [65]

Answer:

False

Explanation:

Mean arterial pressure is obtained by the following equation: (Systolic BP + Diastolic BP + Diastolic BP) / 3.

For example, the mean arterial pressure (MAP) of normal blood pressure in human beings (that is, 120/80 mmHg) would be:

(Systolic BP + Diastolic BP + Diastolic BP) / 3

120 + 80 + 80 / 3

280 / 3

93.3

This is why MAP is closer to diastolic BP than systolic BP.
