When is it appropriate for EMTs to use the Heimlich maneuver?

The Heimlich maneuver, also known as abdominal thrusts, is specifically indicated for cases of a suspected obstructed airway. This situation occurs when a foreign object, such as food or another item, blocks the airway, preventing normal airflow and causing choking. The maneuver is designed to generate enough pressure in the abdomen to expel the object and restore breathing.

In the context of when to administer the Heimlich maneuver, it is critical to recognize the signs of choking, which include inability to speak, difficulty breathing, and distress. The maneuver is an emergency response to restore airway patency, making the understanding of its appropriate use essential for EMTs in their critical care role.
