Fig. (2) Some members of the GlideScope family. Top: The GVL family of reusable GlideScopes. Technical specifications are available in (Table 2). Middle: The GlideScope Direct, designed to assist in the teaching of direct laryngoscopy. It is a reusable video-enabled Macintosh laryngoscope designed for the specific purpose of teaching direct laryngoscopy. In contrast to other devices in the GlideScope product line, such as the GVL, Cobalt, and Ranger, which have a view axis of around 290°, the GlideScope Direct is a Macintosh 3.5 blade with a traditional view axis of 90° along the operator’s direct line of sight. Bottom: The GlideScope Titanium is available in two models. The first is a low-profile hyper-angulated blade, available in two sizes, while the second uses a more traditional Macintosh blade, also available in two sizes. Both designs offer full-color imaging, with LED illumination as well as anti-fog technology. Four models of single-use video laryngoscopes are also available.
