2. Presence of fixed airway obstruction
3. Presence of a chronic neuromuscular disorder
a. 3 only
b. 1 and 2 only
c. 1, 2, and 3
d. 1 and 3 only

Question 2

Whether using traditional methods or the FET, a period of diaphragmatic breathing and relaxa-tion should always follow attempts at coughing. What is the purpose of this approach?

a. To restore the patient's SO2

Answer to Question 1

ANS: A
Mechanical insufflation-exsufflation via an oronasal interface is effective, provided that there is no fixed airway obstruction or glottic collapse during exsufflation.

Answer to Question 2

ANS: B
The period of diaphragmatic breathing and relaxation following the forced expiration is essential in restoring lung volume and minimizing fatigue.
