For starters a little on my background. I'm a certified EMT Basic with 10 years on an Advanced Life Support unit.
Im now law enforcement with several swoopy teams, and will serve as a team medic when we don't have a paramedic or Ambo on standby (which is often). I'm not the end all be all, but I think I know more than the average person.
Best place to shop for supplies these days? I really try to avoid Amazon counterfeit stuff...
I hate to say it, but I use Amazon. If your not concerned with prices, Chinook medical is good shit.
For massive bleeding, still Israeli bandages and quick clot?
Adhesive type wound closures: still steri-strips?
Nothing wrong with Israeli dressings, but can do the same with an ABD pad and a ace bandage. They're just not seen together. For my personal medical storage, more is better. There's no on size fits all, so I watch Amazon deals for major discounts on various gauze and grab a shit load of whatever's on sale. When the time comes to use something I'll use what I need.
Steristrips are a good alternative to sutures. So is duct tape, so is super glue. In the ER they put purple dye in it and call it "derma bond".
What is hot for self-applied tourniquets?
Personal preference, for me it's the latest generation of CAT, that's what I'm issued, and that's what I've trained with. This is something I would NOT get off Amazon, and don't buy a knock off. Actually, I wouldn't be opposed to knock offs for spares. Have a few good ones on your gear or in your vehicles, but keep the knockoffs in reserve. Better to have a knock off than have nothing I guess. Regardless, know which one you have, and get a trainer, or use an old one to train with and lock how to use it and get it on in under 60 secs.
Also would like new bags as well. I was using a generic duffel before for the house kit, smaller duffel for the "OH SHIT" bag, and small generic hiking packs for med kits that fit inside the GHBs. Those could use an upgrade.
Just like anything else as much as you want to spend. You could spend a shit load on PJ packs that you prob don't need. I have an old medical bag that I got when I started my EMS career. Haven't looked at it in years but it's stocked. As far as stuff for home, I've been using plastic totes and little travel organizers off Amazon to organize shit. Works for me.
I'm going to try to talk you out of an AED. Very expensive, most organizations usually end up getting them through grants and donations. But if you have the money to burn go for it. Just know they don't last forever and should be replaced after 5 years. Pads expire yearly, and the battery needs to be checked regularly. It's alot of $ and effort.
I urge you to focus on the basics, specifically sterilization. Peroxide, rubbing alcohol, beta alanine, etc. In a "SHTF" without access to advanced medical treatment, your not going to survive any major trauma. It's just not realistic. But a small cut is completely survivable SO long as you can avoid infection.
