Abdominal thrusts

Abdominal thrusts, also known as the Heimlich maneuver or Heimlich manoeuvre, is a first-aid procedure used to treat upper-airway obstructions by foreign objects. American doctor Henry Heimlich is often credited for its discovery. To performing abdominal thrusts, a rescuer stands behind a choking victim and using the hands to exert pressure on the bottom of the diaphragm. This compresses the lungs and exerts pressure on the object lodged in the trachea in an effort to expel it.
