What is the purpose of the Heimlich maneuver?

The Heimlich maneuver is specifically designed to address a life-threatening situation where an individual has a blocked airway due to choking. This obstruction can prevent the person from breathing, leading to serious complications or even death if not resolved quickly. The technique involves a series of abdominal thrusts aimed at generating enough pressure to expel the object blocking the airway, thus restoring normal airflow and allowing the person to breathe again.

The other answer choices relate to different medical concerns that do not involve choking. Relieving a headache, assisting with breathing difficulties, and providing chest compressions are important first aid procedures, but they are not the focus of the Heimlich maneuver. Understanding the specific application of the Heimlich maneuver is crucial for effectively responding to choking emergencies, making this knowledge an essential part of first aid training.
