REGULATION OF BLOOD PRESSURE
MABP = CO x TPR
Mean Arterial Blood Pressure
Mean Arterial Blood Pressure =
Cardiac Output =
Total Peripheral Resistance =
CO = HR x SV
Cardiac Output
Heart Rate =
Stroke Volume =
Branched Blood Vessel
MABP = DP + 1/3(PP)
Mean Arterial Blood Pressure
Diastolic Pressure =
Systolic Pressure =
Pulse Pressure =
Vasodilation & Vasoconstriction
Hemorrhage
VR = BV/VC
Venous Return
Venous Return =
Blood Volume =
Venous Compliance =
Stroke VolumeSV = EDV – ESV
End-Diastolic Volume =
End-Systolic Volume =
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
