1

Mean Arterial Pressure (MAP)

MAP = CO x TPR
MAP = 2/3 (DBP) + 1/3 (SBP)

2

Cardiac Output

CO = HR x SV (stroke volume)

3

Velocity of Blood Flow

V = Q/A
Q = flow
A = cross sectional area

4

Blood Flow

Q = delta P/R
delta P = pressure difference
R = resistance (changes 4 fold w/ change in radius of vessel - Poiseuille's law)

5

Stroke volume

SV = EDV - ESV

6

Ejection Fraction

EF% = SV/EDV x 100

7

Stroke work

SV x aortic pressure

8

Fick Principle

CO = O2 consumption/ ([O2]pulmonary vein – [O2]pulmonary artery)

9

Total Peripheral Resistance

TPR = (Pa-Pra)/CO
P: arterial pressure
Pra: right atrial pressure

10

Pulse pressure

Pulse pressure = systolic - diastolic; proportional to SV

11

Starling forces equation

driving force = (Pc - Pi) - (pic - pii)
