1. hypoxia inadequate oxygen delivery to the
lungs or body tissues from circu-
lation, hemoglobin, or toxic sub-
stances
2. hypoxemia decrease amount in oxygen in the
blood
3. a SaO2 of 90 indicates mild
______________ hypoxemia
4. At SaO2 of 90%, 60 mmHg
PaO2 = immediate intervention with oxygen
and requires therapy
5. effects of chronic hypoxia fatigue, drowsiness, inattentiveness,
apathy, delayed
reaction time
6. chronic hypoxia s/s enlarged heart, clubbing, anorexia,
constipation, decreased urinary out-
put, decrease libido, weakness of ex-
tremity muscles, muscle pain
7. acute hypoxia effects, s/s Restlessness, disorientation, confu-
sion, impaired judgement, hyper-
ventilation, air hunger, circulatory
changes (tachycardia-bradycardia)
8. Assessments for oxygenation ABG
pulse ox (o2 sat)
physical assessment findings
9. Low flow oxygen delivery systems -Nasal cannula (>4L/min use humid-
ification)
-Simple face mask

ceive oxygen 3L/minute via nasal FiO2 is essentially the percent of
cannula. When calculating the frac- oxygen being delivered by the oxy-
tion of inspired oxygen (FiO2) for this gen-delivery system
setting, which of the following would
be correct?
28%
32%
36%
40%
Calculate:
___ L x 4 + 20 = FiO2 or concentration
of oxygen; each additional L of flow
is + 4%

tient on a Venturi mask of 40%. Which this mask.
explanation best fits this oxygen de-
livery device?
Different masks are used for each de-
sired oxygen concentration.
An air entrainment device blends the
oxygen with room air.
One set oxygen flow rate is used with
this mask.
With a venture, there is variable oxy-
gen delivery.
13. Obstructive sleep apnea partial or complete upper airway ob-
struction during sleep with repeated
periods of apnea, brief arousals re-
sulting in a fragmented sleep.
