VBM offers different adjuncts for the difficult airway to facilitate the placement of an Endotracheal Tube into the trachea (METTI, METTS, Introducer). Due to its length METTI can also be used for tube exchange. Due to their inner channel Introducer and Tube Exchanger allows additional oxygenation. The Stylets are used to pre-form the Endotracheal Tube to facilitate laryngoscopy.
