First up, stop the bleeding. In a car wreck, shooting or stabbing, industrial accident...You'll find that standard first-aid bandages are next to useless. Get some big dressings. ... you're primarily concerned with life-saving measures. Stop the bleeding, make sure the victim is breathing, prevent shock, that sort of thing. Any more advanced care can be administered at the ER.
Yeah, the kit in my car has more "advanced" supplies to deal with major trama which might result in an automobile injury. In that case, a person can bleed out well before EMTs can arrive. But, I don't feel the need for that sort of stuff in my "ouch kit."
By the way, there's an "ouch kit" in the glove box of my car so that in the event of a minor cut, I don't have to pull over, open the trunk, and get out the true First Aid Kit.
There is a definite difference between an "ouch kit" and a First Aid Kit.
An "ouch kit" is about the final treatment for an injury, "Final Aid" as opposed to "First Aid." For a typical, day-to-day, minor cut or scrape, clean it off, dab on some Neo, put a bandaid on it, and that's it, you're good-to-go; it needs no further treatment except maybe repeating the same thing later if it gets dirty, etc. An "ouch kit" could also be called a "Final Aid" kit because no further treatment is necessary.
In a shooting or major industrial accident or car accident, major trama situation, all I can offer is "first aid." In those situations, Final Aid will have to come from a hospital. The class I had taught me, "ABCs," airway, breathing, circulation, shock," in that order. First, make sure that all victims have a clear airway. Next, make sure that all victims are breathing. Third, deal with any circulation -- blood circulation -- problems which includes and major bleeding. Finally, keep all victims out of shock. That's what my FIRST aid kit is about, ABCs.
An ouch kit and a first aid kit, two different things.
