The Department has also recently introduced the GlideScope® for use when controlling a patient's airway during and endotracheal intubation. Intubation is the action of placing a breathing tube into the trachea with the use of a laryngoscope. This equipment takes advantage of fiber-optic technology which allows for a video view of the patients airway during the procedure. GlideScope® equipment has become the equipment of choice for controlling a difficult airway. Fiber-optic laryngoscopy has become increasingly available to pre-hospital providers and is becoming a standard of care in many EMS agencies across the nation; it is currently used in most operating rooms and emergency departments for its success rates with patients who are difficult to intubate.
