Cardio Equations Flashcards
1
Q
cardiac output
A
cardiac output (CO) = heart rate (HR) x stroke volume (SV) [typically ~5 L/min]
2
Q
blood pressure
A
BP = cardiac output (CO) x Total Peripheral Resistance (TPR)
3
Q
pulse pressure
A
pulse pressure (PP) = systolic pressure - diastolic pressure
4
Q
mean arterial pressure
A
mean arterial pressure (MAP) = diastolic pressure + (1/3) pulse pressure
5
Q
stroke volume
A
end diastolic volume (EDV) - end systolic volume (ESV)
6
Q
poiseuille’s equation
A
flow = radius^4
7
Q
Ohm’s law
A
flow = pressure gradient/resistance
