Heimlich maneuver

Heimlich maneuver, emergency procedure used to treat choking victims whose airway is obstructed by food or another substance. It forces air from the lungs through the windpipe, pushing the obstruction out. If the victim is standing, the rescuer wraps his (or her) arms around the victim's waist; making a fist with one hand and placing the thumb side of the fist against the abdomen just above the navel, the rescuer grasps the fist with the other hand and presses in with firm, quick, upward thrusts.

Heimlich maneuver

Emergency procedure for dislodging a foreign body from a choking victim's throat, devised by the U.S. surgeon Henry J. Heimlich. It is used only when the airway is totally obstructed, as shown by inability to speak or breathe. The rescuer reaches around the victim from behind, grasps one fist in the other just below the victim's rib cage, and makes several upward thrusts into the victim's belly. This expels the foreign object with air from the victim's own lungs. An unconscious victim is laid faceup and the thrusts are given by a kneeling or squatting rescuer.
