When do I decide to get an ambulance? If there is no way to evacuate the casualty safely with the equipment that I have at hand.
What gear do I carry? At work, that depends on what the governing body says I need to carry. For pleasure, normally some gauze, a dressing or two, and gaffa tape.
The British Assoc of Ski Patrollers Outdoor First Aid course is about the best I’ve done.
Moving, conscious and talking – i’d probably not have bothered calling an ambulance either.
