  1. increase pressure on airways, alveoli, & pleura during which respiratory phase?
    inspiration
  2. if pressure controlled, increase pressure due to
    increased volume, resistance &/or decreased compliance
  3. if pressure controlled, decreased pressure due to
    decreased resistance &/or increased compliance
  4. the lower the peak pressure the better T/F
    T
  5. plateau pressure should always be below peak pressure T/F
    T
  6. if the ptat and peak are the same range, means the pt has stiff lungs T/F
    T
  7. if you increase pressure you decrease
    BP
  8. decreased venous return to the heart is due to:
    increased intrathoracic pressure
  9. increased vt
    dec pulm venous return to the L vent
    dec PAP

    = to hypo or hypertension?
    hypotension

    MOST COMMON
  10. inc vt
    inc pulm venous return to the L vent
    in PAP

    = to hypo or hypertension?
    hypertension
  11. hemodynamic effects of positive pressure
    • inc of intrathoracic pressure
    • dec in pulm blood vol & inc in sys blood blood vol
    • dec in venous return
    • dec in R vent SV
    • dec in PAP
    • dec in L vent SV
  12. hemodynamics effects of peep
    • inc PAP
    • inc CVP
    • dec aortic pressure
    • dec in CO
    • PEEP dec CO more than CPap
  13. if you decrease CO you will also decrease
    blood flow to liver and kidneys
  14. if pt lacks CO2, it will be more difficult to produce and process
    produce urine

    process drugs
  15. bc of lack of CO, organs/kidneys can't work like they should, so if pt is sedated, kidneys might take longer to excrete medication bc kidneys are not on full function.

    T/F
    T
  16. increased abdominal pressure can:
    • inc thoracic pressure
    • dec CO
  17. errosion of GI lining is caused by
    dec perfusion
  18. TPN increased
    • inc o2 consumption
    • inc co2 production
  19. positive pressure from vent inc/dec ICP?
    increase
  20. if ICP is high, pt is hyperventilating

    T/F
    T
  21. dec c02 may cause cerebral tissue hypoxia

    T/F
    T
