Choking in an unconscious child may occur when the upper airway, usually the throat or windpipe, is blocked by an object or irritation. A child for the purposes of this article is 1 to 8 years old.
Choking is usually caused by objects that the child has placed in his or her mouth. These include toys, candy, popcorn, hot dogs, nuts, batteries, rocks, and buttons. Things that wrap around the neck and constrict it, such as strings or rope, can also cause choking.
