What should be the proper position of the tip of an endotracheal tube?

The proper position of the tip of an endotracheal tube is below the vocal cords and 2-6 cm above the carina. This positioning is crucial for ensuring adequate ventilation and preventing complications. When the tube is placed below the vocal cords, it effectively bypasses the upper airway, allowing for direct access to the trachea and lungs. The specified distance above the carina helps to minimize the risk of intubation-related injuries, such as damage to the mainstem bronchi, which can occur if the tube is inserted too deeply. Furthermore, placing the tube at this level facilitates optimal alveolar ventilation while allowing for proper suctioning and preserving airflow through both main bronchi.

Maintaining this appropriate distance is essential for clinical effectiveness and patient safety, shaping the foundation for successful airway management in various respiratory scenarios.
