The detailed anatomy really stands out on this adult intubation trainer. It offers a clear picture of human anatomy from the sculpted alveolar sac, bronchial tree, and blood vessel structures of the cross-sectioned and exposed flexible lungs, to the interior main bronchus and oral/nasal pharyngeal spaces. These details, with an airway complicated by breakout teeth, tongue edema, and laryngospasm, has this airway trainer rated hard. The anatomical stomach, which will swell with esophageal intubation, or excessive pressure with the BVM during rescue breathing, along with the vomiting capability of this trainer makes an exceptional educational tool for multitasking. Includes instructions for use, hard carry case, lubricant, and replaceable lungs and stomach. Three-year warranty.
