Get real, people! The whole idea of a jump kit is not to be able to treat an entire MCI, but to hold you until duty units arrive. Jump kits should be small and lite - some of yours must take three men and a boy to carry. Why not focus on the items you need to deal with life threats and leave it at that?? Airway - OPA kit, pocket mask, D tank with 1 NRB and 1 tubing (for the pocket mask). Breathing - asherman chest seal, items listed in airway. Circulation - dressings, kling wrap, triangulars, tape. Stethoscope, BP cuff, penlite, shears, forceps. You can add a sam splint set for frac mgt (takes up very little room), and an oral glucose. Treat the life threats and everything else can wait until the bus arrives. Keep it simple, lightweight, and portable.
