Would anyone be up to answering some medical type questions? It's for future fic, the story after the one I'm posting today. Unlike the writers of Grey's Anatomy and House, I don't have staff medical writers [g] But I have you!

1: There's been a major earthquake and buildings have fallen on top of people. What are some of the technical terms for the sorts of crush injuries that would occur?

2: In a triage situation, I know they use different coloured tags on patients to designate who gets treated and in what order, and some people who are too hurt to be treated at all. What are the different levels and tag colours?

3: Anything else I should keep in mind?

Thank you!
