Once you've obtained permission you can only do what you've been trained. Do not exceed your training otherwise you open up a whole can of worms. I was cls certified and my roommate was our corpsman. So I learned alot. Worked as a medical assistant for awhile then became a phlebotomist for a spell. Cousin is a nurse and her man is a dr. Everything I have learned and heard is don't exceed your training and you will be good once you have permission bEcause than you will be covered under good samaritan laws. If they are unconscious than do the basics to maintain your (primary) and their (secondary) safety. Wait until ems arrives. If there bleeding out stop the bleeding though.
