Answer to Question 1

ANS: D
These devices are ideal in situations where electrical power is unavailable (e.g., during certain types of patient transport) or as a backup to electrically powered ventilators in case of power failures. They are also particularly useful where electrical power is undesirable, as near magnetic resonance imaging equipment.

Answer to Question 2

ANS: B
Drive mechanisms can be either (1) a direct application of compressed gas via a pressure reducing valve or (2) an indirect application via an electrical motor or compressor.
