Abdominal Thrust

The American Red Cross and the American Heart Association both agree that the recommended first aid for choking victims is the abdominal thrust, also known as the Heimlich manenver, after its creator, Dr. Henry Heimlich, Slaps on the back are no longer advised and may even prove detrimental in an attempt to assist a choking victim.
* Get behind the victim and wrap your arms around him above his waist.
* Make a fist with one hand and place it, with the thumb knuckle pressing inward, just below the point of the ''v'' of the rib cage.
* Grasp the wrist with the other and give one or more upward thrusts or hugs.
* Start mouth-to -mouth resuscitation if breathing stops.
