A definitive airway is defined as any intervention that is below the level of the ____.

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

Answer: (C)

In airway management, a definitive airway is one that is secured below the level of the vocal cords, into the trachea, so it bypasses the upper airway and provides protection against aspiration. This is why endotracheal tubes and surgical airways, which pass through the vocal cords, are classified as definitive. Devices that sit above the cords, such as supraglottic airways, do not meet this criteria because they don’t bypass the protective structures and may not guarantee secure ventilation. The boundary used here is the vocal cords (the glottic level), so the term below that level correctly refers to a definitive airway.
