As a drug delivery route

Oxygen and other compressed gasses are used in conjunction with a nebulizer for topical delivery of medications to the upper and lower airways. Nebulizers use compressed gas to propel liquid medication into an aerosol, with specific therapeutically sized droplets, for deposition in the appropriate, desired airway. Compressed gas, usually at flows of 8 10 L/min, is used to nebulize medications, saline and sterile water into a theraputeic aerosol for inhalation. In the clinical setting room air (ambient mix of several gasses), Oxygen and Heli Ox gas are commonly used to nebulize small, large and continuous volumes of liquid.
