Which of the following is false about the optimal technique for using a small-volume jet nebulizer (SVN) for aerosol drug delivery?

Question

Quizplus · Accepted Answer

Use of an SVN is less technique- and device-dependent than use of a pressurized metered dose inhaler or dry powder inhaler delivery system. Slow inspiratory flow does optimize SVN aerosol deposition. However, deep breathing and breath-holding during SVN therapy do little to enhance deposition over normal tidal breathing. Because the nose is an efficient filter of particles larger than 5 mm, many clinicians prefer not to use a mask for SVN therapy. As long as the patient is mouth-breathing, there is little difference in clinical response between therapy given by mouthpiece and that given by mask.
