As a former EMT, I am not a real fan of "flash cards" for first aid. I guess that they are OK if you have a tummy ache and wonder what might have caused it, but for real emergency aid you usually don't have time to search thru the cards to find out where the pressure point is to stop arterial bleeding (assuming that direct pressure hasn't worked). You have to KNOW what to do, NOW. A small reference book for illnesses is another story...
