As a school bus driver I was required to take Red Cross first aid training every two years. BrianLe is correct that the major emphasis of these trainings was recognizing the problem and calling 911 for anything that seemed to be serious. Wilderness first aid was nowhere on the agenda and whatever could be applied from one to the other applied only to very minor problems that most of us learn to cope with, without any Red Cross training.

Take a wilderness first aid course, if you would like to learn what you'd need to know out on the trail.
