Which of the following events occur when the mean airway pressure exceeds 50 cm H2O?
 
  a. The oscillator decreases by 50.
  b. The pinch valve closes to decrease pres-sure.
  c. The dump valve opens, causing the oscil-lator to stop.
  d. The mean airway pressure is reduced by 25.

Answer to Question 1

ANS: C
The mean airway pressure alarm greater than 50 cm H2O is activated if the mean airway pressure rises above 50 cm H2O for any reason. When this alarm is activated, the dump valve opens, caus-ing the oscillator to stop.

Answer to Question 2

ANS: C
With the sensor in place, AutoFlow functions in the continuous mandatory ventilation, synchro-nized intermittent mandatory ventilation, and mandatory minute ventilation modes.
