What is the proper technique for performing the Heimlich maneuver on an adult?

The Heimlich maneuver, also known as abdominal thrusts, is a critical first aid technique used to relieve choking in adults. The proper technique involves standing behind the person in distress. By placing your hands just above their navel and performing inward and upward thrusts, you create pressure that can help expel the object blocking the airway. This upward thrust action is essential as it directs force towards the diaphragm and can effectively dislodge an obstruction.

The significance of the positioning—standing behind the person—not only provides stability but also ensures that you can generate enough force to effectively dislodge the obstruction. It’s essential to perform this maneuver with the right technique to avoid causing injury while maximizing the chance of removing the blockage.

Other options might suggest techniques that are not appropriate for a choking emergency or are significantly less effective at generating the necessary force to relieve the obstruction. For instance, standing in front and pulling someone toward you would not create the necessary pressure needed during this type of emergency. Patting someone on the back might inadvertently push the object further down instead of dislodging it. Squeezing the person's waist tightly does not apply the specific and effective pressure needed to clear an airway obstruction and can lead to discomfort or injury.
