NAPS-airway rescue

I'm working on a case study that involved an anesthesia airway rescue resulting from RN-administered sedation in a remote (non-OR) location. I have pulled up numerous articles on the subject but I'm just wondering how many on this forum have ever experienced such an event. Whether propofol was involved, or fentanyl, midazolam, or brevital and etomidate are even now being used by RNs for conscious to moderate sedation, I'd be interested to hear the story.

I realize this is a controversial topic and I am not interested in starting a dog fight. I would just like to know how prevalent an issue this is from this casual survey and if it has happened, the circumstances under which it occurred.

Thanks,
Z
