"Visualization of the Intubation Pathway With the IRRIS-Device"

IRRIS will be attached to the patient's neck skin just beneath the laryngeal prominence. Tracheal intubation will be performed by using a video-laryngoscope in a standardized Fashion and by guiding the tracheal tube into the Larynx by following the visual Signal on the Screen that is caused by IRRIS. The handling of IRRIS and the Performance of tracheal Intubation will be recorded. Patients will be monitored for safety parameters and possible adverse events during the study until recovered and released from the postoperative care unit.
