gas exchange numbers only Flashcards
1
Q
when v/q = 0, PO2 is
A
40 because no ventilation so no oxygen to alveoli so same as deoxygenated blood
2
Q
when v/q = infinity, PO2 is
A
149 think “infinite ventilation”
3
Q
when v/q = 0, PCO2 is
A
- because you aren’t getting ventilation in there to exchange, so its the same as deoxygenated blood
4
Q
when v/q = infinity, PCO2 is
A
0 blow it all off
5
Q
when v/q is normal, alveolar P02=
A
100
6
Q
when v/q is normal, alveolar PCO2 =
A
- on the lower side because diffusion is happening
7
Q
po2 of inspired air
A
150
8
Q
pCO2 of inspired air
A
0 because CO2 comes from the body not the atmosphere
9
Q
p02 of venous blood
A
40 because remember it goes from 40 to 100
10
Q
pCO2 of venous blood
A
45 high because its deoxygenated
