Which explains why cool-mist vaporizers rather than steam vaporizers are recommended in home treatment of childhood respiratory tract infections?
a. They are safer.
b. They are less expensive.
c. Respiratory secretions are dried.
d. A more comfortable environment is produced.
ANS: A
Cool-mist vaporizers are safer than steam vaporizers, and little evidence exists to show any advantages to steam. The cost of cool-mist and steam vaporizers is comparable. Steam loosens secretions, not dries them. Both may promote a more comfortable environment, but cool-mist vaporizers present decreased risk for burns and growth of organisms.
