Answer to Question 1

ANS: A
When the pressure-release valve is activated, it indicates that the threshold resistor or spring-loaded valve is jammed, and the patient's exhaled volume is not exiting through the con-tinuous positive airway pressure valve. This is not proper function and indicates that the device needs to be replaced.

Answer to Question 2

ANS: C
The Downs continuous positive airway pressure generator uses a spring-loaded valve to adjust the amount of pressure.
