If SV = 94mL/beat and SBP = 133mmHg, what is MBP?

Solution

Ans. In cardiovascular physiology, stroke volume (SV) is the volume of blood pumped from the left ventricle per beat. The mean blood pressure (MBP) is usually determined by the equation given below -

MBP = diastolic blood pressure (DBP) + 1/3 (systolic blood pressure (SBP) – diastolic blood pressure (DBP)).

In the given question SV = 94mL and SBP = 133mmHg

The Stroke Volume (SV) = DBP – SBP

94 = DBP - 133

Hence, DBP = 133 - 94 = 39

Now, MBP = 39 +1/3(133-39)

MBP is approx. 70 mmHg
