What does the Heimlich maneuver aim to accomplish in cases of obstructed airways?

The Heimlich maneuver aims to create pressure that expels the obstruction, effectively dislodging a foreign object from the airway. This technique involves applying abdominal thrusts to increase intrathoracic pressure, which helps to forcefully expel the obstruction blocking the airway. When performed correctly, the sudden increase in pressure can make it difficult for the object to remain lodged, allowing for a potential release and thus restoring normal breathing.

In the context of obstructed airways, this method is critical because a clear airway is essential for effective respiration. Time is of the essence when someone is choking, and the Heimlich maneuver serves as an immediate action to prevent severe complications or fatalities related to asphyxiation.
