If an adult is choking and cannot breathe, there's no sound able to exit their mouth and they are conscious, you need to 1. call 911; 2. get permission to the Heimlich maneuver (abdominal thrusts).

Taking it a step further; if the person does become unconscious, you will then begin CPR to attempt to thrust the obstruction out of the airway.
