I agree if you can take the EMT class it would be better, but I am an EMT.

Another option would be a Wilderness medic class(WEMT), if you have that option in your area.

One of the best Wilderness Medical classes I have taken was sponsored by NASAR.....National Association of Search and Rescue. It was a week long 24/7 class taught by Paramedics and physicians started at "OH"600 and went to midnight, taught in classroom and in the field. Final day was an in field all day/night exercise.
