“…The manufacturers of other videolaryngoscopes (GlideScope, Verathon, WA, USA and Mc.Grath Series 5, Aircraft Medical, Edinburgh, UK) advocate midline insertion and the use of a styletted endotracheal tube. Both the Airway Scope (Pentax-AWS system; AWS; Pentax, Tokyo, Japan) and the Airtraq (ATQ; Prodol Meditec, Vizcaya, Spain) are anatomically shaped rigid indirect videolaryngoscope intubation devices with an adjustable built-in monitor; both devices provide an indirect view of the glottis without requiring the laryngoscope's line of sight [17][18][19]. These devices use a tube channel in the right side of the blade which holds the endotracheal tube and directs it towards the vocal cords.…”
