A chronic obstructive pulmonary disease (COPD) patient receiving ventilatory support in the CMV assist-control mode at a rate of 14 and a VT of 750 ml exhibits clinical signs of air trapping.
 
  Which of the following would you recommend to correct this problem?
  1. Decrease E time.
  2. Increase the inspiratory flow rate.
  3. Decrease the assist-control rate.
  a. 1 and 2 only
  b. 1 and 3 only
  c. 2 and 3 only
  d. 1, 2, and 3

Question 2

Which of the following ventilator adjustments would decrease inspiratory time? 1. Increase the peak flow. 2. Increase the tidal volume. 3. Change the flow pattern from a decelerating wave to a square wave.
 
  a. 1 and 3 only
  b. 1 only
  c. 2 and 3 only
  d. 1, 2, and 3

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.
