Ok, since I don't see very many scenarios here, I'll start one. I'm putting this here since there isn't a scenario forum. Rules: You are ALS, regardless of level. Points awarded for thought process in figuring out what is going on. At the start, you are on a standard ALS unit. This might change. Again, I'm looking for "what's going on and how to treat it" than "high flow O2, IV, monitor, transport." This is run by you, the posters. When you ask questions, you will be rewarded with answers. The opening post is vague for a reason. Feel free to assume that you have taken BSI and that the scene is safe because this is not about those.
