hemodynamics Flashcards
1
Q
CO =
A
CO = SV x HR
2
Q
Q =
A
Q = [delta]P/R
3
Q
pressure drop from arterial to venous pressure
A
measure of potential energy lost
indicates PR used to overcome resistance
4
Q
[delta] P =
A
[delta] P = Q x R
[delta] P = CO x TPR
5
Q
effect of radius on flow
A
small increase in radius = large increase on flow
[by a power of 4]
via decreasing the resistance
6
Q
max HR =
A
~ 220-age
7
Q
exercise can change
A
SV : almost double
HR
8
Q
in smaller tubes, describe the velocity
A
smaller tube = greater velocity
9
Q
arterioles are known as ________ (with respect to pressure)
A
resistance vessels
10
Q
where is blood “stored?”
A
venous system
“capacitance”
