EMT Sheri, I work for Durham EMS in North Carolina, and it could get so busy that we often run out of ambulances. We do things pretty quickly here, especially in red-tag medical or trauma calls. However, for the most part (just like anywhere else), the calls we respond to are either bogus or not serious enough for us to "load and go." By the way, when I say that I joke around during bad calls, I don't mean to say that I become a stand-up comedian. For example, one night my first call was for a bad shooting and the dude was bleeding all over the place. It was the nastiest and bloodiest call I've been to. However, I told the fire fighter who was in the back with me and my partner, "What a way to start the night, huh," while I was smiling.
I don't think it's so much of the education that makes us calm, though it helps a lot when you know exactly what you need to do. No matter what call you go on, ultimately everything would be done the same way. Everything is routine no matter what: ABC's, initial assessment, control life-threatening situations first, so on, so on. Besides, it's the patient's emergency, not mine, so why freak out
I usually have a saying on the job: "It's all gravy, man."
