Have fun!
While this does not directly answer your question, it could help you understand some of what is going on. (Note from your mother: Finish reading your book now, if you have not already. Nothing will make as much sense without the theoretical framework of the rescue book.)
There are two broad varieties of rescue courses:
1. Self-rescue, prevention, awareness, and reaction-focused courses.
2. Team Rescue focused courses, with huge scenarios and costumes and fake blood etc.
I know that option 2 courses are usually raved about by the people who do them because, at times, it's one big action movie the students get to play parts in. But it requires an instructor who has a clique of divers, Divemasters etc to work because there have to be several non-students playing roles as well as the instrcutor evaluating everyone. Even people who come back to help with these courses tend to rave about them. I help out as a cast member sometimes, and I take Japanese Divemaster candidates along when the stars align.
Personally I only teach type 1 courses for the practical reason that a rescue class will happen on a tourist's timing which makes gathering the cast for a type 2 impossible. There is also the philosophical point that I am of the opinion that the best rescue that happens, happens so invisibly that no one ever saw it happen. People who can instantly diagnose and solve a partially (or fully!) closed valve underwater could only kind of say they did a rescue (since it is only a type 1), but if they could not, then they would be forced to do a type 2 rescue.
I have been part of the type 2 style scenarios, but in real life, and I am not sure how having done the type 2 scenarios in training would help average rescue trained diver actually be able to be useful in the real world scenarios. But having done the type 2 scenarios certainly would make them more aware of what we were doing and why. In the end, when I am involved in a rescue/transport, it is all we can do to keep even experienced people from getting in the way so really all I want from around me is people with language abilities, local driving direction and place name knowledge, and a cellphone with good reception. So few people have delivered emergency O2 or done CPR in real life situations, so unless I know that the person trying to do it has actually done it, I am going to be having to do it myself instead while shouting directions to the person with the phone on what to say to fire/rescue to make sure they can find the dive site since they don't know the names that divers call them.
(Flow rate matters more than anything else. If the victim is starved for air, they will not keep the mask on. This is true underwater on scuba, and on the deck on free-flow O2 masks. The root problem is different, but people are remarkably consistent in how they react to basic input.)
