My first ED was a freestanding ED, without RTs ever. Or pharmacy. Or L&D. It was just us! We had a CT and x-ray with the appropriate people for those, but could only get ultrasound after hours if we suspected torsion. In any case, I learned a lot about vents. I wasn't skerred of the intubations because I was a paramedic for 5 years before I became a nurse, but I made sure I knew how to work the vents, to include various modes (SIMV, BiPAP, etc.), giving in-line albuterol treatments, what the alarms meant, how to troubleshoot, etc. I also got really good at getting ABGs! I loved it there. Good luck!!
