10
Q
What happens to volume-time graphs of FVC in obstructive diseases?
A
FEV1:FVC is reduced to ~70%
11
Q
What is FEV1?
A
Forced expiratory volume in 1 sec
12
Q
What would be seen in a flow loop graph of a patient with an obstructive disease?
A
Initial decrease and smaller volume overall
13
Q
What would be seen in a flow loop graph of a patient with a restrictive disease?
A
Reduced volume and narrower loop
