Introduction: Pre-hospital airway management is complex and complications occur frequently. Guidelines advice using waveform capnography to confirm correct tube position, but in the emergency setting this is not universally available. Continuous visualization of the airway with a video tube (VivaSight SL (TM)) could serve as an alternative confirmation method, provided that airway structures are properly recognized. With this study we wanted to investigate whether airway management practitioners were able to recognize anatomical structures both in a circulated and in a non-circulated airway.
