I've done a weeks first aid training - the Health and Safety at Work one. Very good, I learnt a lot (most of which I've forgotten a year later). One of the instructors was a biker, so he also showed me how to safely remove a helmet (only to be done if patient not breathing).
One thing he did say is that even without training, if you see a defib unit hanging on a wall nearby, use it, even if not trained. He say's you can't go wrong.
