For what purpose is the Heimlich maneuver used?

The Heimlich maneuver is specifically designed to dislodge an object that is obstructing a person's airway, which can occur during choking incidents. The technique involves applying abdominal thrusts to increase pressure in the chest cavity, thereby expelling the lodged object and restoring airflow to the lungs. This lifesaving action is crucial during emergencies when a person cannot breathe due to an obstruction, making it distinctly different from other medical procedures like CPR, assessing vital signs, or treating bleeding. Proper knowledge of this maneuver is vital for first responders and bystanders to effectively intervene in choking situations.
