Endotracheal Tube Introducer

An Endotracheal Tube Introducer (Bougie) is a semi-rigid, flexible guide used to facilitate endotracheal intubation in difficult airway scenarios. Providing tactile feedback through characteristic clicks as it passes over tracheal rings, it serves as a rescue device when direct laryngoscopy fails. Essential for anesthesia, emergency medicine, and critical care, it is a standard component of difficult airway management algorithms.
