Securing a definitive airway early is crucial in smoke inhalation because airway edema and inhalation injury can progress quickly, making obstruction and respiratory failure a real risk. An endotracheal tube provides a secured airway, protects the lungs from secretions and inhaled soot, and allows reliable delivery of high-flow oxygen and ventilation with positive pressure as needed. Tools like a laryngoscope are important for performing the placement, but they don’t by themselves protect the airway or guarantee ventilation. An oropharyngeal airway can help keep the airway open in an unconscious patient, yet it does not prevent aspiration and does not provide reliable ventilation in the presence of airway edema. A nasal cannula only delivers supplemental oxygen and does not secure or protect the airway, especially when inflammation and swelling threaten airway patency. Therefore, securing the airway with an endotracheal tube is the best choice.
