Which emergency technique is used to clear a person's airway?

The abdominal thrust maneuver, commonly known as the Heimlich maneuver (choice B), is an emergency technique specifically designed to clear a person's airway when they are choking. When a person is unable to breathe due to a blockage in their airway, the abdominal thrust technique involves a series of quick inward and upward thrusts, applied just above the navel, to create pressure and forcefully expel the obstruction from the airway.

Although "abdominal thrust" and the "Heimlich maneuver" often refer to similar actions, both terms can be conflated or used interchangeably in many contexts. The introduction of the abdominal thrust technique provided a formal name for a method that has been widely recognized in emergency response training. Therefore, while referring to the technique, it may be more precise to call it by its widely understood name, the Heimlich maneuver, which is why some may see this answer as more commonly accepted.

In life-threatening situations where airway obstruction occurs, this technique is essential for the responder to recognize and apply effectively, emphasizing its importance in emergency care protocols.
