I carry a medium adventure medical first aid kit. To it, I added iodine tabs, another compression bandage, some extra alcohol wipes, some more antihistamine, and extra latex gloves.
This is for backcountry travel, not biking, btw.
Duct tape is on my Nalgene bottles and hiking poles. Tampons are part of my emergency fire starter kit, along with a magnesium striker and two lighters. I carry about 100 feet of paracord.
Also, two space blankets and one poncho. I usually have an old school crazy creek chair with me. Otherwise I can scavenge splint material from tent poles if I have to. I always carry a large, full tang knife in a sheath too that could work as an immobilizer with some duct tape.
One thing I recently added that I didn’t used to carry is a fully charged Mophie and two wires - one for iPhone and one for android.
If all of these in combination don’t do the trick, or at least provide enough stabilization for a reasonably fit person to high tail it to the trailhead and get real help, then the unfortunate event is not survivable.
Risk mitigation is possible. Risk elimination is not. I’m fine with 5 extra pounds, give or take, for the former, but for the latter, a team of sherpas is required.
I think it’s laudable,
@Monique, to want to carry the most useful kit to help everyone. And this is a great topic to discuss. At some point though, the kit carried becomes good money (weight) after bad.
