Endotracheal tubes (ETT) are used in anesthesia to maintain an open airway during surgery. They are inserted into the trachea through the mouth or nose and secure in place with a cuff that seals the trachea and prevents air from leaking. ETTs are connected to an anesthesia machine and a breathing circuit for mechanical ventilation. ETTs also protect the airway from aspirating stomach contents and secretions. Comes in a pack of 100 units.
