The saline solution is used as an inhalant for respiratory illness...nebulized saline can be used to humidify airways. If a patient is having decreased oxygen intake due to illness, adding just dry air can irritate the lining of the lungs. Using a small amount of nebulized saline can ease the the process by decreasing damage to the cilia, which are tiny "brooms" that move particles through mucous membranes.
Maintaining a smooth unobstructed airway is vital in patients, but it also has recreational uses. The "Journal of Speech, Language, and Hearing Research" compared water-nebulized soprano singers to a saline-nebulized group. The saline group exhibited better vocal effort than water alone.
The isotonic saline nebulizer device turns 0.9 percent sodium chloride into a mist for inhalation. It is commonly used by both patients and health care professionals to treat respiratory illness. Although traditionally viewed as a placebo, nebulized isotonic saline can be beneficial in patients with a respiratory illness. Other studies have shown it has ergogenic uses as well.
OK, so what do you think happens with e-cig atomized partial saline solution?
