What is the purpose of the Heimlich maneuver?

The Heimlich maneuver is specifically designed to remove foreign objects that are obstructing a person's airway, which is critical in situations of choking. When an object becomes lodged in the airway, it can block airflow to the lungs, leading to asphyxiation. The maneuver creates an abrupt increase in pressure in the person’s chest and abdomen, forcing air out of the lungs and pushing the obstruction out of the airway.

The other options do not align with the primary purpose of the Heimlich maneuver. Relieving abdominal pain does not pertain to treating airway obstructions. Alleviating moderate coughing is not the focus of this procedure; coughing itself can be a natural response to expel an object, but in cases of severe choking, the Heimlich maneuver is necessary. Additionally, administering emergency medication is unrelated, as the Heimlich maneuver addresses a physical blockage rather than a medical condition requiring medication. Thus, the correct understanding of the Heimlich maneuver emphasizes its role in restoring airflow by removing obstructions from the airway.
