Answer to Question 1

ANS: A
A pneumatic circuit, or pathway, is a series of tubes that allow gas to flow inside the ventilator and between the ventilator and the patient.

Answer to Question 2

ANS: C
Proportional solenoid valves control flow by opening and closing either completely or in small increments. These valves, which are driven by various motor-based mechanisms, have a rapid re-sponse time and great flexibility in flow control. The other answers are all volume-displacement devices.
