Answer to Question 1

ANS: C
High-frequency chest wall oscillation is accomplished by using a two-part system: (1) a variable air-pulse generator and (2) a nonstretch inflatable vest that covers the patient's entire torso (The Vest Airway Clearance System).

Answer to Question 2

ANS: C
Typically, respiratory therapists perform 30-min therapy sessions at oscillatory frequencies be-tween 5 and 25 hertz (Hz). Depending on need and response, between one and six therapy ses-sions may occur per day.
