I recently took a 9 day course and received my Wilderness First Responder (WFR)Certification. It is commonly called a “Woofer” certification. Included as part of this course is my CPR Certification. This course teaches you the basics of what to do when a medical emergency occurs in the backwoods. Basically, anytime you are either one mile into the woods and/or are more than 1 hour from patient care (hospital, EMT’s, etc) this is considered Backcountry versus an Urban environment.
This was probably one of the most practical and best courses I have ever taken. You hope you never need to use most of it! A few pictures are located here.
