Answer to Question 1

ANS: C
Higher flow (up to 100 L/min) may improve gas exchange in COPD patients, probably because of the resulting increase in expiratory time.

Answer to Question 2

ANS: A
To decrease inspiratory time, one may increase the peak flow, decrease the tidal volume, or change from a down ramp or sine wave to a square wave flow pattern.
