Honestly, if a person isn't, they'll know it and already know which components they need anyway. That's sort of a non-answer, but I meant to convey that I'm asking people with little to no medical training in case anyone wants a good place to start for intermediate trauma/medical preparedness.
If you know you'll be using advanced or surgical airways (and other higher level stuff), then this would be a boring build. It's going to be for my travel kit. My home or work kit would have these things in addition to other systems for more advanced care. I'm happy to share that stuff too, but it isn't all that useful for average people in every day life (meaning non-professionals).
