For choking, ask a person to speak, it they cannot, proceed. Stand behind the person; place one arm around the person’s waist. Make a fist, place it just above the navel below the ribs and breast bone, and grab the fist with the other arm around the waist. Push inward and upward with a quick hard thrust and repeat. If the person is lying face up on the floor, straddle the person and apply pressure above the navel quickly.
