I value this forum and its community immensely. And I came here to listen and learn. But I can't hold my tongue on this one.
With all due respect (and I SERIOUSLY mean that)...
You only get one you. Sounds goofy but ponder it for a moment. The corollary to that is that your family only gets one you.
S**t happens. Refuse to acknowledge that at your own risk.
Approach first aid / trauma care as a descending scale from "you go home in a bag" to "ouch, that hurts!".
Do your own risk assessment looking at the probability and severity of such an event. An arterial bleed is not likely but the severity is profound. I personally choose to acknowledge that severity. For things lower on the severity scale, I weigh the weight/bulk of my response to how much I am likely to snivel if it happens. Case in point: I have sissy feet. So I suck up the couple of ounces to carry a blister kit so I don't have that convenient excuse not to hump that extra mile or two.
So here goes my sermon:
At the very absolute minimum carry the items necessary to address a traumatic bleeding event. For me that is a tourniquet and a pressure bandage.
Arrows are surgically sharp and firearms.... well, we all get that. Whether it's you in a moment of epic dumba33ery or some idiot that "thawt yoo wuz a deer", if you find yourself face-to-face with an arterial bleed in the woods and don't have a way to staunch that flow, just sit down and call your significant other to say goodbye. A CAT or SOF-T wide tourniquet takes up almost no room and a good pressure bandage (Israeli / OLAES, etc) is not much bigger. When I leave my truck I always have on me a small IFAK that carries a tourniquet, pressure bandage, hemostatic, chest seal, and tape. It's about the same size as a can of monster. In my pack will be a boo-boo kit with gauze, bandaids, tincture of benzoin, alcohol wipes, and about 10 feet of NAR Gecko Grip tape wrapped around an old hotel key card. That kit is roughly the size of my wallet.
The boo-boo kit saves the trip. The trauma kit saves me.
By far the most important tool in a trauma event is your mind. Having the training and composure to "calmly" handle the event and not wig out outweighs any amount of gear you can carry. That training doesn't just apply to the woods either. Life is littered with opportunities for disaster to strike. Car wrecks, household accidents, natural disasters, the list is endless. A very good friend of mine heard his (then) 11 year old son scream bloody murder in the back yard one afternoon. The kind of scream that makes your hair stand straight up and your blood run cold. He ran out to find that his son had come down wrong on the trampoline and had a severe compound fracture of his left femur. The sharp bone had twisted and sliced into his femoral artery. Blood was everywhere. He ripped off his shirt and had the other kids (who were about to pass out) apply direct pressure while he ran back to the house. He called 911 as he ran. He then grabbed the tourniquet off his daily carry pack for work and ran back out to his son. Applying the tourniquet, he was able to stop the massive blood loss. The time from 911 call to ambulance on scene was 15 minutes. His son would have bled out were it not for his intervention. His son had a couple big surgeries but made a complete recovery and is very active in sports to this day.
Soooo.... If your'e feel'in my gospel, seek out the training and go through a reputable vendor for quality supplies. An EMT or paramedic that orbits in your social solar system is a great place to start. In a pinch, just stop by the local fire dept and ask for guidance. There are tons of online resources but vet them carefully. And lastly, don't buy your tourniquet off of Amazon. There are way too many crappy chinese fakes on there to warrant the risk.
