Go heavy on PPE (Personal Protective Equipment) latex gloves, a barrier device for mouth-to-mouth such as a pocket mask or microshield, maybe even some combo facemask/eye shields. Remember, things can get pretty messy when you start slinging a lot of snot, spit, and blood around in a traumatic event. Israeli bandages are super cool, if you can lay your hands on them without paying through the nose. The older style surplus field dressings work just fine, too. Throw in an ace wrap or two if you have room, especially in the absence of the Israeli bandages. Some individually wrapped 4x4 dressings are pretty much standard, as well as some roller gauze (kerlix or kling.) A couple of triangular bandages, some cloth tape, a pair of trauma shears, and, don't forget the band-aids. (You'll feel really stupid to discover that you have a bunch of high-speed, low-drag medical gear and yet not be able to slap a band-aid on a minor boo-boo.) Nice to have but not really essential stuff includes some oral airways, maybe a one-handed tournaquet, a SAM Splint or ladder splint, some alcohol and betadine preps, and a couple of disposable scalpels. Don't sweat the ALS gear like IVs and such, since that will probably be a major hassle to obtain unless you are an advanced medical care provider. Oh, and most importantly, get that training updated. CPR standards just changed dramatically, and you'll be suprised what you may have forgotten. Good luck.
