A jump kit is the primary trauma bag carried by EMTs and paramedics. It contains a base set of things, and other customization items. It offers redundancy for things that are also into the ambulance, as well as redundancy in itself.
We have a very good friend who is a paramedic, and he gave us the master list of things he always carries with him. (His kit lives in his ambulance, and so no pictures...sorry about that.)
EMT Jump Kit
Sterile OPAs (Oropharyngeal Airway) (infant, adult, child)
4" x 4" (12 count)
5" x 9" (4 count)
Trauma dressing (2)
Coban (6 count) (aka self-adhering bandage)
Cravats bandage (4 count)
Adhesive tape (2)
blood pressure cuff (adult)
sterile saline (500ml)
cold packs (2 count)
wrapped tongue depressors (2 count)
adhesive bandages (6 count)
exam gloves (2 pairs)
petroleum gauze (occlusive)
emesis bags (aka vomit bags)
surface cleaner (ex. hydrogen peroxide)
elastic bandage (aka ace bandage)
Of course, all this is almost useless if you don't know how to use it. Take a first aid class to learn!
This is what the EMTs carry. What else do you think would be handy in a first aid kit? What would your additional items be? Let us know below.
A good base kit that is ready made is this one: Lightning X Deluxe Stocked Large EMT First Aid Trauma Bag Fill Kit w/Emergency Medical Supplies
It contains most of the above list, plus or minus a few items.
