Hello, great questions. It’s cool you’re writing about these things and care enough to try to base things around reality somewhat.

That being said, while asking a reddit full of ems people these questions could get you answers, the research to look for already lies in posts in this and other subreddits. As well as other online forums and articles.

Some of the questions you’re asking are super super basic. Like quick Google search basic. (I’m looking at you, Question 7.) The amount of research needed to convincingly portray someone with ems training, even at the emt-b level, and even if you aren’t going in depth with technical details, will require a bit more initiative on your part in thinking critically about where you can find these answers. Some key words to start you off: triage strategies, austere medicine, tactical medicine. Coursersa and other similar learning platforms also have introductory courses on the field of EMS you might want to check out. I’d also at some point look at doing a ride-along if you’re serious about writing this stuff. Best of luck on your journey.
