MABP = DP + 1/3(PP)

Mean Arterial Blood Pressure

Diastolic Pressure =

Systolic Pressure =

Pulse Pressure =

Frank-Starling LawThe Frank-Starling Mechanism states that the greater the volume of blood entering the heart during diastole, the greater the volume of blood ejected during systolic contraction.

Frank-Starling Law =

Response to Decreased MABP

1. Venoconstriction

2. Increased Contractibility

3. Increased Heart Rate

4. Vasoconstriction
