Nonglare Material Helps Portable Video Laryngoscope Provide Clear View for Emergency Intubations

June 16, 2008 – Fast intubations are performed in emergency situations where extreme conditions and severe trauma are common, but the key to success is a clear view of a patient’s airway, which is why a nonglare screen is important when using video layngoscopes.

Verathon Medical Canada ULC offers the GlideScope, which uses a small video camera that mounts inside the endotracheal tube to help clinicians get a clear view of the vocal chords and helps technician insert the tube. To get a clear view on the miniature video screen the company uses Clarex non-glare materials, provided by Astra Products, Baldwin, NY.

Verathon said its video laryngoscope incorporates micro-video technology and helps in dealing with standard and difficult intubation cases. The GlideScope, originally introduced in 2001, has a smaller version, the GlideScope Ranger that was introduced in 2006. It provides a clear picture of the larynx and vocal cords on a display monitor, enabling visual control of the endotracheal tube (ETT) in its trajectory toward the airway. With its patented 50 to 60 degree viewing range, integrated camera, and patented anti-fogging mechanism, the Ranger facilitates fast, accurate ETT placement even in difficult airways, and helps prevent improper ETT placement and related complications in emergency, out-of-hospital situations. The Ranger is compact for easy carrying and storage, measuring 7 1/4 x 6 3/8 inches and weighing less than two pounds, and is operational in seconds. With its rugged, high-impact plastic construction, the Ranger was designed to be dependable in an array of field conditions, including temperatures of -4° to 122° F, humidity up to 100 percent, and altitude up to 20,000 feet. It is powered by integrated, rechargeable lithium polymer battery that provides minimum 90-minute continuous-use autonomy and allows for about 20 intubations per battery cycle (depending on usage).
