During the Heimlich maneuver, where should the fist be placed on the patient?

The Heimlich maneuver, or abdominal thrusts, is an essential technique used to help someone who is choking. The correct placement of the fist is crucial for the effectiveness of this technique. In the provided scenario, the fist should be positioned above the belly button, specifically in the area of the upper abdomen, just below the ribcage. This positioning allows for a powerful upward thrust, which is necessary to expel the obstruction blocking the airway.

When the fist is placed above the belly button, you can apply the necessary force effectively by pulling inward and upward. This is vital because the thrust must generate enough pressure to force air from the lungs, creating sufficient pressure to dislodge the object causing the choking.

The other options would not provide the same level of effectiveness. Placing the fist at the sternum, in the middle of the abdomen, or at the base of the rib cage would not deliver the same upward force necessary for removing an obstruction, potentially putting the person at greater risk. Proper technique and placement are critical for the safety and success of the maneuver.
