When someone is unconscious and their airway is obstructed, the first priority is to get air into the lungs. Opening the airway and providing ventilation establishes oxygen delivery right away, which is essential because the person can’t protect their airway or breathe effectively on their own. Using a head-tilt or jaw-thrust maneuver to open the airway allows air to pass, and delivering breaths (with a bag-valve-mask or mouth-to-mask) can help move air past the obstruction and support breathing. The Heimlich maneuver is intended for a conscious person who is choking and can’t speak or breathe, so it isn’t the immediate action once the patient is unconscious. Suctioning alone won’t restore ventilation, and CPR is reserved for situations where there is no pulse or no detectable circulation. So, the quickest, most appropriate first step is to open the airway and ventilate to restore oxygenation.
