Card Set Information
What happens to the cardiac/vascular graph with positive inotropicity?
OC move counter-clockwise
**increased CO = increased SV = less RAP
What happens to the cardiac/vascular graph with negative inotropicity?
OC moves clockwise
** CO decreases = SV decreases = More RAP
What happens with increased venous tone?
decreased compacitance = decreased unstressed volume
What happens with decreased venous tone?
Increased capacitance = increased unstressed volume
What is the stress diff. b/t arteries and veins?
Which is more elastic, veins or arteries?
***Veins are more collapsible
If your RAP increases, what happens to EDV and CO?
EDV & CO increase
If RAP decreases, what happens to EDV and CO?
EDV & CO decrease
If you increase RAP, what happens to atrial filling and venous return?
Atrial Filling =
Venous return =
If you decrease RAP, what happens to atrial filling and venous return?
atrial filling =
venous return =
Mean systemic pressure
When the RAP is maxed out and there is no venous return
