To perform abdominal thrusts (the Heimlich maneuver) on someone else

• Stand behind the person. Place one foot slightly in front of the other for balance. Wrap your arms around the waist. Tip the person forward slightly. If a child is choking, kneel down behind the child.
• Make a fist with one hand. Position it slightly above the person's navel.
• Grasp the fist with the other hand. Press hard into the abdomen with a quick, upward thrust — as if trying to lift the person up.
• Perform between six and 10 abdominal thrusts until the blockage is dislodged.

A modified version of the technique is sometimes taught for use with people who are pregnant or obese. The rescuer places his or her hand in the center of the chest to compress, rather than in the abdomen.
