A non-rebreather mask delivers oxygen but provides no ventilatory support. For a patient with a depressed respiratory drive, immediate endotracheal intubation and positive pressure ventilation are required to reverse hypoxia and prevent cardiac arrest.
Never place a submersion victim in the Trendelenburg position; it increases intracranial pressure and aspiration risk. Airway and breathing interventions always precede detailed diagnostics like ABGs.
