Well... There is nothing to stop you from doing a little self instruction in this area. You could grab a EMT book and read outside of a classroom. You would not have the hands on practice but you could still educate yourself well enough to make it worthwhile. Here is a link for the book I used in EMT class.

Just a thought...
I feel like I could get myself in a lot of trouble, only reading and not having any practical experience or someone saying "HAY! Don't do it that way."
