28
Q

What happens to the following values in pregnancy:

ERV
RV
FRC
TLC
IC
VC
TV
RR
Minute ventilation
FEV1
DLCO

TV- ↑ by 30-50% (progesterone mediated incnrease in central respiratory drive)
RR - no change or mild ↑
Minute ventilation ↑ by 20-50%
FEV1 - no change
DLCO - ↑ then ↓
29
Q
A 26-year-old woman is
evaluated for dyspnea on
exertion. PFTs show FEV1
84%, total lung capacity
96%, ERV 50%, FRC 76%,
and DLCO 119%. These
findings are most
consistent with what
diagnosis?
A

Obesity can cause a
reduction in ERV and FRC
and an increase in DLCO.

30
