Key Equations Flashcards
1
Q
Give the equation for cardiac output.
A
Cardiac Output (CO) = Heart Rate (HR) x Stroke Volume (SR) [typically 5 L/min]
2
Q
Give the equation for stroke volume.
A
Stroke Volume = End Diastolic Volume (EDV) - End Systolic Volume (ESV)
3
Q
Give the equation for Ohm’s law.
A
Ohms law states: Flow = Pressure gradient/Resistance
4
Q
What does the following equation calculate?
CO x Total Peripheral Resistance (TPR)
A
Blood pressure
5
Q
What does the following equation calculate?
Systolic pressure - Diastolic pressure
A
Pulse pressure (PP)
6
Q
What does the following equation calculate?
Diastolic pressure + 1/3 PP
A
Mean Arterial Pressure (MAP)
7
Q
State Poiseuille’s equation.
A
Flow = radius^4
