Title: The C-MAC Videolaryngoscope Compared With Conventional Laryngoscopy for Rapid Sequence Intubation at the Emergency Department
Brief Summary: All patients undergoing emergent endotracheal intubation (RSI) at the Emergency Department will be screened for inclusion in this clinical study. The indication of endotracheal intubation is an exclusively clinical decision and is not affected by this study protocol in any aspect.

If fulfilling the In- and exclusion criteria's, patient will be randomly assigned to one of two groups

1. C-MAC Videolaryngoscope in appropriate size
