How and when do people normally learn first aid for martial arts. My master said he knows how to revive an unconcious person, fix broken adams apples and other things that martial artist learn to hurt.
First aid is first aid.
The cause of the injury is irrelevant.
Take a First Aid class at your local Red Cross.
If you are talking about self defense...
One does not worry about rendering first aid to an attacker.
You just incapacitate him and get yourself out of the situation as quickly as possible.
BTW: Your master is probably talking about a tracheotomy for a broken Adam's apple. Cut into the windpipe and stick a straw, Bic pen handle or some similar instrument into the wind pipe which will allow air to enter into the lungs.
