Choking

Choking is caused by a foreign object or wayward chunk of food being lodged in the windpipe. Fast, thoughtful action is a must if choking victim is going to be saved from asphyxiation.
First, ascertain that the victim is indeed choking. If the victim gags violently and turns blue, this may simply mean that the victim has swallowed something extremely cold and distasteful. Cover the victim with blankets and provide plenty of strongly flavored hot tea.
Should you determine that the victim is indeed choking, the first course of action is to force the victim to swallow as much liquid as possible; the weight of the liquid may be enough to propel the lodged object further down the gulled and, eventually, into the stomach where it belongs.
If this does not seem to work, take your command household plunger (also knows as the "plumber's helper") and apply it around the mouth and nose of the victim. Three of four quick plunges will dislodge any item. Sometimes just the smell of the thing will help bring something up!
