Lung Volumes Flashcards
1
Q
Vital Capacity
A
VC = IRV + VT + ERV
2
Q
Inspiratory capacity
A
IC = IRV + VT
3
Q
Functional residual capacity
A
FRC = ERV + RV
all of the air that remains in your lungs at the end of a normal passive respiration
4
Q
total lung capacity
A
TLC = ERV + RV + IRV + VT
5
Q
Dead Space: anatomic
A
conducting airways that were never meant to exchange O2 and CO2
6
Q
Dead space: alveolar
A
alveoli that get air but do not get blood
-no exchange occurs here bc no blood. so work it took to get air here is wasted
7
Q
Physiologic dead space
A
the sum of anatomic and alveolar dead space
