Answer to Question 1

Any flow measured in the first half of the FVC reflects on the bronchi; any flow measured be-yond 50 of the vital capacity reflects on the bronchioles.

ANS: B
Compared with the normal flow-volume loop, a fixed upper airway obstruction produces a curve that appears box-shaped.
