REGULATION OF BLOOD PRESSURE

Mean Arterial Blood Pressure MABP = CO x TPR Mean Arterial Blood Pressure = Cardiac Output = Total Peripheral Resistance =

Cardiac Output CO = HR x SV Heart Rate = Stroke Volume =

Branched Blood Vessel

Mean Arterial Blood Pressure MABP = DP + 1/3(PP) Diastolic Pressure = Systolic Pressure = Pulse Pressure =

Vasodilation & Vasoconstriction

Hemorrhage

VR = BV/VC Venous Return Venous Return = Blood Volume = Venous Compliance =

Stroke Volume SV = EDV – ESV End-Systolic Volume = End-Diastolic Volume =

Frank-Starling Law The 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 Response to Decreased MABP 1. Venoconstriction 2. Increased Contractibility 3. Increased Heart Rate 4. Vasoconstriction
