The advancement of the endotracheal tube has closely followed advancements in anesthesia and surgery.[2] Modifications have been made to minimize aspiration, isolate a lung, administer medications, and prevent airway fires. Despite advances with the endotracheal tube, more research to optimize its use is necessary. For example, ventilator-associated pneumonia (VAP) is a major concern, and the ETT itself is felt to be a primary agent for the development
