Important Equations Flashcards
1
Q
Cardiac output
A
Cardiac output= stroke volume x heart rate
CO = SV x HR
2
Q
Blood pressure
A
Blood pressure = cardiac output x total peripheral resistance
BP = CO x TPR
3
Q
Pulse pressure
A
Pulse pressure = Systolic pressure - diastolic pressure
4
Q
*mean arterial pressure
A
Mean arterial pressure = Diastolic pressure + 1/3 pulse pressure
MAP = Diastolic P + 1/3 PP
5
Q
Pouisseile’s law
A
Flow= pi x r^4 / 8 x length x viscosity
6
Q
Ohms law
A
Flow=pressure gradient/resistance
I = V/R
