What positioning technique is used for the Heimlich maneuver theory?

The Heimlich maneuver is designed to expel an obstructing object in a choking victim's airway. To perform the maneuver effectively, the rescuer needs to adopt a stable and secure stance. Positioning the feet shoulder-width apart with one foot in a lunge position allows the rescuer to maintain balance and leverage while delivering upward thrusts. This stance ensures that the individual can generate sufficient force to dislodge the obstruction while keeping themselves steady, reducing the risk of losing balance during the procedure.

In contrast, standing tall with feet together could compromise balance and stability, making it difficult to apply the correct force. Squatting down may not provide the necessary height and leverage needed for the maneuver. Sitting with legs crossed is not appropriate as it would hinder mobility and the ability to effectively perform the thrusts required to resolve the choking situation. Thus, the technique involving feet shoulder-width apart and one foot in a lunge position is essential for executing the Heimlich maneuver successfully.
