incorrect
9.
What is the patient's VD/VT if their PaCO2 is 58 mm HG with a mixed expired CO2 of 32 mm Hg?
incorrect
10.
What is the formula for alveolar partial pressure of carbon dioxide (PACO2)?
A.
0.45
B.
200mL/min
C.
0.3
D.
70 pack years
E.
PACO2 = VCO2 X 0.863 divided by VA(alveolar ventilation per minute)
F.
Alveolar ventilation/min = respiratory rate x alveolar ventilation (tidal volume - dead space volume)
G.
1151 minutes. 19.18 hours
H.
minute volume = respiratory rate x tidal volume
I.
VD/VT = PaCO2 - PeCo2/PaCo2
J.
2.15 L
Type the Answer that corresponds to the displayed Question.
