SVN stands for which term?

• A. Subcutaneous Volume Nebulizer
• B. Standard Volume Nebulator
• C. Small Volume Nebulizer
• D. Serum Volume Nebulizer

Answer: (C)

In inhalation therapy, the abbreviation SVN refers to a device that turns a small amount of liquid medication into a fine aerosol for inhalation. The term Small Volume Nebulizer captures the idea that only a small volume of solution is needed to deliver the medication to the lungs, typically via a mouthpiece or mask with driving flow from air or oxygen. This makes SVN a common choice for delivering bronchodilators and other inhaled drugs in both prehospital and clinical settings.

The other options describe terms that aren’t standard for aerosol therapy delivery. Subcutaneous Volume Nebulizer would imply a route of administration that isn’t how nebulized medications are given. Standard Volume Nebulator and Serum Volume Nebulizer aren’t recognized terms for this device or procedure.
