Apneic laryngeal oxygenation during elective fiberoptic intubation – a technical simulation

摘要

Prototype of an oropharyngeal oxygenation device (OOD) from the back (A) and the front side (B). The OOD is split to form a path (a) for the bronchoscope (b), with an external lumen to provide oxygen insufflation into the deep laryngeal space (c)
