Unintentional endobronchial, or “mainstem,” intubation can lead to high peak inspiratory pressures during mechanical ventilation, hypoventilation, and hypoxemia. However, the ETT may also be placed into the mainstem bronchus intentionally for surgery. In addition, endobronchial intubation may be useful in managing patients with unilateral lung pathology and is essential in certain emergency situations.
