Stand behind the person
Wrap your arms around their waist
Make a fist with one hand
Place the thumb side of your fist just above the navel and below the ribcage
Grasp your fist with your other hand
Give quick, inward and upward thrusts
Repeat until the object is expelled
If the person becomes unresponsive, call emergency services and begin CPR if trained
For a pregnant or obese person, place your hands higher on the chest and perform chest thrusts
For an infant under 1 year, do not perform the Heimlich maneuver; use back blows and chest thrusts instead
