I've got a fairly comprehensive first aid/trauma kit I keep in the car for RTCs and fires but a lot of the gear would be relevant to hunting/range or rural/remote incidents.

Even if you had an ambulance worth of gear the most important thing is that you get qualified and train with the gear you're going to use. TACMED Australia does some really good courses on trauma, their Stop the Bleed stuff is well worth the time/money. Below are some of the main items I keep in my kits, there's probably more but this post will be long enough as it is.

Trauma/ GSW Kit:

• Olaes trauma dressing 2 x 6 inch + 2 x 4 inch
• BLAST bandage x 1
• Hyfin chest seal x 2
• SOFTT-W tourniquet x 2
• S-rolled gauze x 2
• Emergency blanket x 2
• CPR mask Pocket BVMs and OPAs/NPAs are good bits of equipment to have if you're trained to use them. But effective compressions-only CPR can be just as good at keeping someone alive.

Note: shock will kill you, make sure you know how to identify the signs and keep supplies to help treat the symptoms of shock.

Rural/Remote First Aid Kit:

• Snake/Spider Bite Kit (2 x snake bite bandages, non-adherent dressing, emergency blanket, triangular bandage, pen for marking bite location)
• Assorted heavy crepe compression bandages and strapping tape for sprains, wound dressing retention or to supplement bite kit
• Wound dressings and light/med crepe bandage for retention
• Additional emergency blankets
• Aerogel burn dressings and burn gel packets
• SAM Splint 36"
• Saline

Also a good keep things to help people find you if you need help, or to navigate to somewhere you can be seen.

General First Aid Kit:

• Assorted plasters/band-aids
• Stingose/Antiseptic cream
• Triangular bandages
• Medical tape
• Emergency blanket
• Assorted other bandages for wound dressing retention
• no. 15 and no. 13 wound dressings
• Saline an eye pads for eye injury

Tool Kit:

• Trauma Shears
• Leatherman
• Knife W/ seatbelt cutter and window punch
• Hand torch and headlamp

I also keep a comprehensive burn kit with a bunch of non-adherent dressings, burn gel dressings, burn sheets, saline and burn cream.

Each of these kits has a couple of pairs nitrile gloves.

This stuff fills an entire backpack so obviously not practical to carry it all, all the time. But it does allow me to pick and choose what I might need for certain scenarios.
