Equations for Exam I Flashcards
1
Q
Net Filtration Pressure (NFP)
A
NFP = (Pc - Pif) - (np -nif)
if it’s + = filtration
if it’s - = absorption
2
Q
Cardiac Output (CO)
A
CO = HR x SV
3
Q
Stroke Volume (SV)
A
EDV - ESV
4
Q
The Fick Equation (VO2)
A
VO2 = [HR x SV] x (A - V O2 Difference)
5
Q
Ohm’s Law (C)
A
C = change in P / vascular R
*Resistance does not stay the same!
6
Q
Pouseille’s Law (F)
A
F = [pi x change in p x r^4] / 8nl
radius = biggest factor of equation n = blood viscosity l = length of vessel
7
Q
Diastole is ___ time of the HR ratio
A
2/3
8
Q
Systole is ___ time of HR ratio
A
1/3
9
Q
If the HR is 72bpm, how long is the heart in diastole?
A
0.50s
10
Q
If the HR is 72bpm, how long is the heart in systole?
A
0.33s
