How effective is the Heimlich maneuver?

The Heimlich maneuver is generally effective for expelling an object lodged in a person's airway, allowing them to breathe again. Its success largely depends on the promptness and proper execution of the technique. While the maneuver can save lives in cases of choking, it may not be effective for everyone, particularly in cases of complete airway obstruction or if the individual is unconscious. It's essential to seek medical attention even after successfully dislodging an object, as injuries may still occur.
