hypoxia - inadequate oxygen delivery to the lungs or body tissues from circulation, hemoglobin, or toxic
substances
hypoxemia - decrease amount in oxygen in the blood
a SaO2 of 90 indicates ______________ hypoxemia - mild
At SaO2 of 90%,
PaO2 =
and requires - 60 mmHg
immediate intervention with oxygen therapy
effects of chronic hypoxia - fatigue, drowsiness, inattentiveness, apathy, delayed
reaction time
chronic hypoxia s/s - enlarged heart, clubbing, anorexia, constipation, decreased urinary output,
decrease libido, weakness of extremity muscles, muscle pain

High flow oxygen delivery systems - -Venturi mask
-transtracheal catheter

A physician orders a patient to receive oxygen 3L/minute via nasal cannula. When calculating the
fraction of inspired oxygen (FiO2) for this 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% - Answer: B. 32%
FiO2 is essentially the percent of oxygen being delivered by the oxygen-delivery system
An order is received to place a patient on a Venturi mask of 40%. Which explanation best fits this oxygen
delivery device?

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 oxygen delivery. - One set oxygen flow rate is used with this mask.
