What action should the respiratory therapist take?
a. Replace the continuous positive airway pressure device
b. Decrease the flow rate
c. Increase the pressure level
d. Remove the pressure-release valve
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.
