Airway Devices

Abstract

This chapter explores commonly used devices for placement of endotracheal tubes, including direct laryngoscopy techniques, fiberoptic devices, video laryngoscopy, and transillumination. The focus is on how the device works, and unique aspects of each technique. Direct laryngoscopy relies upon creating a line of sight from mouth to larynx to visualize insertion of an endotracheal tube. Video and fiberoptic technologies rely on indirect visualization (either through viewing lens or video screen) and do not require alignment of oral, pharyngeal, and laryngeal axis. Transillumination relies upon the anterior positioning of the trachea, and ability to see a bright light emitted from inside the trachea as a red glow on the patient’s neck.
