Answer to Question 1

ANS: B
HFOV differs from other types of high-frequency ventilation in several ways; for example, both inspiration and expiration are active in HFOV.

Answer to Question 2

ANS: B
The MAP and FIO2 controls are used to control the patient's oxygenation. The amplitude and frequency are used to control the patient's ventilatory status.
