A definitive airway is defined as any intervention that is below the level of the what?

• A. Vocal cords
• B. Trachea
• C. Epiglottis
• D. Larynx

Answer: (A)

Definitive airway means securing the airway by going below the opening of the vocal cords, crossing into the trachea. The vocal cords form the glottic boundary; devices that sit above them—such as simple oropharyngeal or nasopharyngeal airways and many supraglottic devices—don’t bypass the laryngeal inlet and aren’t considered definitive. When you place something like an endotracheal tube or perform a tracheostomy, you’re passing below the cords into the trachea, which provides airway protection and a stable pathway for ventilation. The epiglottis and larynx are structures around this boundary, but the defining level is the vocal cords.
