Prevention
How can smoke inhalation be prevented? To prevent fires, make sure that electrical wiring, chimneys, wood stoves, and space heaters are working properly. Use flammable liquids safely and store them in a locked area out of the reach of children. [uhs.berkeley.edu]
The results of this study underscore the need for early diagnosis of inhalation injuries and prevention or treatment of associated life-threatening complications. [woundsresearch.com]
