B. 1.7 h
C. 2.2 h
D. 3.6 h – E cylinder = 0.28
1900×0.28\/4 = 133\/60 = 2.21

PaO2: 58 mmHg
What should the RT recommend at this time?
A. Place the patient on CPAP
B. Increase the O2 to 70%
C. Intubate and place the patient on mechanical ventilation
D. Change to a nonrebreathing mask – A. Place the patient on CPAP
Given the following data, what is the patient’s total arterial O2 content?
pH: 7.41
PaCO2: 37 mmHg
PaO2: 88 mmHg
HCO3: 26 mEq\/L
SaO2: 95%
Hb: 14 g\/dL
A. 12 mL\/dL
B. 14 mL\/dL<\/p>\n\n\n\n
C. 16 mL\/dL
D. 18 mL\/dL – (Hb x 1.36 x SaO2) + (0.003 x PaO2)
(14 x 1.36 x 0.95) + (0.003 x 88)
18.088 + 0.264
= 18.352
Answer: D. 18 mL\/dL
