- ANSWER 4
9. Excessive amount of oxygen in the blood? - ANSWER hyperoxemia
10. ACCP recommendations state that oxygen therapy is indicated when PaO2 is
less than ______ mmhg, or SaO2 is less than ____% - ANSWER 60; 90
11. Oxygen therapy is most effective when hypoxemia is caused by (relative/true)
shunting - ANSWER relative
12. Oxygen therapy can be most precisely delivered with (low flow/ high flow)

delivers an FiO2 of approx. ____ - ANSWER FiO2 0.24
14. _______ oxygen administration systems have the most widespread use
because of their simplicity and patient comfort - ANSWER low flow

, 17. In general, mechanical ventilation should not be initiated in COPD unless pH
falls below ____ and all else fails 7.20
18. Non oxygen sensitive patients
•Absent of any chronic lung disorders (asthma, COPD, etc)
•Target PaO2 goals: 60 to 80 mm Hg
•When PaO2 falls below 55 mm Hg, short term memory is altered
19. Oxygen sensitive patients
•COPD, acute severe asthma, chronic hypercapnia
•Excessive oxygen therapy could be fatal
•Target PaO2: 60 mm Hg
20. Sitting
in acute congestive heart failure, cardiac output is likely best in the
(sitting/supine) position
sitting
in the elderly or obese patient, PaO2 is usually highest in the (sitting/supine)
position
PEEP
(oxygen/PEEP) therapy is the most effective treatment for absolute shunting
improves
PEEP usually (improves/worsens) ventilation perfusion matching
accumulation
respiratory acidosis threatens acid base balance through the (accumulation/loss)
of carbonic acid
COPD
