This should almost be two discussions.
One part on breathing and severe bleeding, which if used will be accompanied by a maximum attempt to get help (spot or whatever).
The second part is everything else.
It seems to me that the life saving part of the kit, for most people, is just a CPR mask and a combat kit (hunter trauma kit). With more skills, or specific conditions of a group member, that list might be expanded (e.g. epi pen).
Or perhaps three parts
- life saving
- avoidance of seeking non-emergency care ( enough bandages, antibiotic, ant-diarrhea medicine, etc.)
- comfort (everything else)
Lack of clarity of purpose is part of the reason I feel the first aid kits suck. I looked at a $30 American Red Cross kit that had a CPR mask. So 1/3 to 1/2 of the cost of that kit goes towards rescue breathing for strangers. A nice idea, but not necessarily logical.
