Which of the following are true about continuous positive airway pressure (CPAP)?
 
  1. It maintains alveoli at greater inflation volumes.
  2. It holds airway pressure essentially constant.
  3. It provides the pressure gradient needed for ventilation.
  4. It has side effects similar to those of positive pressure ventilation.
  a. 1 and 3 only
  b. 1, 2, and 4 only
  c. 3 and 4 only
  d. 2, 3, and 4 only

Question 2

During volume-assured pressure-supported ventilation, if the desired VT is not reached or ex-ceeded at the preset pressure support level, what happens?
 
  a. Flow continues at a constant rate until the desired volume is achieved.
  b. The breath terminates when a predeter-mined low flow is achieved.
  c. Flow decreases exponentially until the de-sired volume is achieved.
  d. Flow increases linearly until the desired volume is achieved.

Answer to Question 1

ANS: B
Because airway pressure does not change, CPAP does not provide ventilation.

Answer to Question 2

ANS: A
Although a minimum tidal volume is guaranteed, volume-assured pressure-supported ventilation allows tidal volume to exceed the set level according to patient demand.
