Answer to Question 1

ANS: D
Relative contraindications to NIV include severe upper airway dysfunction, copious secretions that cannot be cleared by spontaneous or assisted cough, or O2 concentration requirements ex-ceeding 40.

Answer to Question 2

ANS: D
Nonetheless, negative pressure ventilation may be appropriate in those patients who are unable to use or who have failed noninvasive positive pressure ventilation trials. Negative pressure ventila-tion may also be considered for patients who require frequent airway access for suctioning or those with severe nasal congestion.
