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