Suction techniques and proper cuff inflation may also be practiced and evaluated. In addition, this trainer has an "airier" airway with more room to maneuver, and a slightly anterior position, making it a great trainer for introductory classes as well as advanced students. Also, applying cricoid pressure changes the position of the trachea and closes the esophagus, so the Sellick maneuver can be realistically practiced. Features durable, rugged, one-piece construction. Comes with training stand to mount head, pump spray lubricant, and hand carrying hard case. Three-year warranty.
