In reply to ebdon:
I made my own cheat cards. They just have a series of basic headings starting with Life-threatening bleeding, Spinal Injury, Shock, Head/Brain Injuries, Heart Attack etc; finishing up with things like Teeth, Bites, Stings. Under each heading I just have basic notes about signs and symptoms, further symptoms that may manifest over time and what to do about them, along with things I might want to do differently depending on whether the casualty is conscious or not.
I managed to get everything I wanted on four sheets of A4 (with sensible sized text) which I then stuck back to back and laminated to make two double sided sheets. These fit neatly down the back of my rucksack's main compartment where they are easily accessible and they won't turn to mush if it's raining hard when I need them (which it will be of course!).
Most of the information on them came from "Outdoor First Aid" by Katherine Wills. I just worked right through the book (after having been on one of her courses) to make sure I didn't miss anything off.
Her website has a downloadable casualty report form which is useful for remembering what information needs collecting.

I printed some at A4 size, put a couple of folded ones in my first aid kit and laminated a couple of others to go with the cheat cards. The laminated ones can be written on with a Chinagraph pencil.
