I have seen "Wilderness First Aid" courses, which if I remember correctly, assume that emergency services are more than 1 hour away. In this way, certain measures which would be considered "drastic" in the city, can be taught in the pretense that you can do it, but only if you're in the wilderness.

I also believe they offer "Wilderness EMT" and "Wilderness Paramedic" courses around the country. You however must hold a valid EMT or Paramedic certification first.
