Answer to Question 1

ANS: A
Hospitals use large, piston-type, water-cooled compressors to supply wall gas outlets.

Answer to Question 2

ANS: B
In a double-circuit ventilator, the primary power source generates a gas flow that compresses a mechanism such as a bellows or bag-in-a-chamber. The gas in the bellows or bag then flows to the patient. In a single-circuit ventilator, the primary power source travels directly to the patient. The closed and open loop refer to whether or not the ventilator has a feedback loop system.
