Interesting tatoos. I was always taught that if a person is unconscious then you can give first aid if you want to. Its up to the first aider regardless of the person's desire not to be resusitated. They are now unconscious so they are not able to make a decision on whether they want first aid. Its up to the first aider.
Now if the person was lying there with a masive sucking chest wound and they are conscious and they say they don't want first aid then none is given. As soon as they pass out apply first aid if you want to.
In Canada we have the Good Samaritan Act which basically says this. So nobody here has to worry about getting sued.
I think that the US is the place where people sue others for saving their lives. I don't understand places where everyone sues everyone, seems rather silly.
