[H. J. Heimlich (1920–), American surgeon] An emergency procedure to remove a blockage in the trachea to prevent asphyxiation, if treatment with up to five back slaps fails. The rescuer stands behind the casualty encircling him with their arms and grasping their hands together. The rescuer clasps one hand over the closed fist of the first hand and places them on the patient's abdomen, midway between the umbilicus and the xiphisternum. The rescuer then pulls upwards and inwards in a sudden sharp movement aiming to dislodge the obstruction. This action may be repeated up to five times.
