These courses are way below the level of training that ski patrollers get. As others have said, the National Ski Patrol has their own course called Outdoor Emergency Care. It is an 80+ hour course. Patrollers are also required to have Professional Caregiver CPR. The OEC course is similar to an EMT-B level course in scope and content. If you are a doctor, nurse, paramedic, or EMT it is possible to challenge the course (but there is special content for the outside environment which you should attend class for before taking the written and practical test as a challenge.
At one time I was an OEC instructor, assistant patrol director, toboggan instructor and well on my way to earning my Senior level credentials, having passed the Senior Level OEC and preparing to take the senior level ski and toboggan portion. Unfortunately, due to personal and family reasons I was unable to attend a couple of my refreshers so I lost all of my NSP certifications. I am currently taking the courses again and have my final exam next week.
If you would like more information on the course you can contact me by PM or the email attached to my profile. Sled is also a great source as he is an OEC instructor. There are several other patrollers on this board as well, they may be able to answer other questions (area and regional specific) for you.
The background klkaye mentioned is nice, but it is not at a level that would allow you to become a patroller. Do check with the area you wish to patrol at, they may have an upcoming course you can enroll in. They may also have a program for prospective candidates (before they take the course, to see what patrolling is really like and all about)
