Answer to Question 1

ANS: B
Commonly used output control valves include the pneumatic diaphragm, electromagnetic pop-pet/plunger valve, and the proportional valve. Descriptions of these devices can be found in res-piratory care equipment textbooks.

Answer to Question 2

ANS: D
To understand mechanical ventilators, we must first understand their four basic functions:
 Input power
 Power transmission and conversion
 Control system
 Output (pressure, volume, and flow waveforms)
