Imagine this, it's two weeks after the SHTF and you running low on AAs and there isn't a D cell around for 200 miles without a paranoid trigger finger between you and it. Your Maglite is dead, your comms radios are about to be done, and smoke signals draw too much attention. If you haven't thought about this before, then how about now?
Prepping is not just for a SHTF senario when the world comes burning down around our ears, like post Sandy/Katrina, or war reaching our shores. How about making life livable if you lose your job? How much are those bills you pay every month? What can you rapidly remove or reduce from your daily life to make your monthly deficits affordable on an unemployment check and/or with freelance income?
Which one should be used and why from a users perspective.
Quick-Clot (US Based) made by Z-Medica uses Kaolinite which is a kind of clay and cannot be broken down by the body. When I have seen it used, it has burned on contact and needed to be cleaned out of the wound later. DoD users have reported difficulty in gaining formulaic documentation from the manufacturer.
Celox (UK Based) made by Celox Medical uses Chitosan, a natural polysaccharide, and is broken down by Lysozyme (found in human tears, saliva and mucus) into glucosamine (a natural sugar). It does not set off a clotting cascade, but clots the red blood cells it comes in contact with. From what I have seen it does not burn on contact and does not need to be cleaned out of the wound. I have no DoD information, but it is mandatory medical kit for the U.K. Military.
Personally - I'll take Celox over Quick-Clot.
