  2. Adjust ventilator volume or pressure limit for added flow.
  3. Disconnect or bypass heated humidifier system.
  4. Turn off flow-by or continuous-flow while nebulizing.

Answer to Question 1

ANS: A
Under normal conditions with heated humidification and standard jet nebulizers, pulmonary deposition ranges between 1.5 and 3.0.

Answer to Question 2

ANS: A
Box 39-9 outlines the optimal technique for drug delivery by SVN to intubated patients under-going mechanical ventilation.
