What is the depth of the endotracheal tube intubation?

The depth of the endotracheal tube intubation is generally about 14 cm, and there will be some differences according to the height of the patients. Generally speaking, when the endotracheal intubation is performed, after the tip of the endotracheal tube passes the glottis, it must enter 1-2 cm further. Then squeeze the balloon to make the judgement. If it is in the trachea, breath sounds can be heard in both lungs. If the tracheal intubation is mistakenly inserted into the bronchus, there will be breathing sounds on only one side, and no breathing sounds on the opposite side. If you accidentally enter the esophagus, there will be no breath sounds on both sides, and there will be abdominal bulges.
