Answer to Question 1

ANS: B
Pneumatic ventilators may incorporate components such as air entrainers, needle valves, flexible diaphragms, and spring-loaded valves to perform certain functions. Electrically powered ventila-tors most often use electrical power to run internal motors for operating pistons and may have internal direct current batteries, which can provide electrical power during patient transport or in the event of a power failure.

Answer to Question 2

ANS: C
The most common problem with the pneumotachograph relates to probe position.
