For the conscious choking victim,it is recommended to encourage the victim to cough, followed by hard back slaps and if none of these things work; abdominal thrusts (Heimlich maneuver) or chest thrusts. Abdominal thrusts are performed with the rescuer standing behind the person choking and exerting inward and upward pressure with their hands on the choking person's abdomen. The purpose of abdominal thrusts is to create pressure that will expel any object lodged in the airway upwards to relive the obstruction.
