What advice do you give if abdominal thrusts are used?

If abdominal thrusts (Heimlich maneuver) are performed, ensure that the person is truly choking and unable to breathe, cough, or speak. Stand behind the person, place your arms around their waist, make a fist with one hand, and position it just above the navel. Grasp your fist with your other hand and thrust inward and upward sharply. After several thrusts, if the person does not become unblocked, call emergency services for further assistance.
