The Heimlich maneuver is a series of under-the-diaphragm abdominal thrusts. It is recommended for helping a person who is choking on a foreign object (foreign-body airway obstruction).

In an effort to simplify training of cardiopulmonary resuscitation, the Heimlich maneuver is the only method for clearing a blocked airway recommended for adults at this time.

The Heimlich maneuver lifts the diaphragm and forces enough air from the lungs to create an artificial cough. The cough is intended to move and expel an obstructing foreign body in an airway. Each thrust should be given with the intent of removing the obstruction.

Performing the Heimlich maneuver
Grasp the choking person from behind, around the abdomen. Place your fist just under the breast bone. Squeeze quickly and firmly, pulling your fist in and up to dislodge the food or object stuck in the airway (trachea). Repeat as needed.
