Answer to Question 1

ANS: C
Since its introduction in 1947, intermittent positive-pressure breathing has been used for a variety of reasons, including short-term ventilatory support, lung expansion therapy, and as an aid in de-livering aerosolized medications.

Answer to Question 2

ANS: C
The Percussionaire Intrapulmonary percussive ventilation provides a form of oscillator therapy that delivers high-frequency percussive breaths into the patient's airways. It is used as an adjunct for mobilizing airway secretions.
