I noticed that no one mentioned us in the medical links...

The site is more useful if you register.
We, ummm... wrote a book that you might be interested in:
Survival and Austere Medicine, 2nd edition. You can download it here for free, or you can buy a copy at cost (we don't make anything) from Cafe Press:

Yes, I'm one of the authors. We're trying to get a third edition out the door, with a lot more hands on procedures and how to, but it's been really slow going...
Austere medicine is a lot different than what you learn in EMT school.
IV solutions are most often used to stabilize someone on the way to surgery, if there is no surgery to go to, they become mostly irrelevant for this purpose.
They can also be used to establish a life line - if you have IV drugs and know how to use them.
They are also used to feed patients that can't eat.
You can make your own IV solutions.
BP cuffs and C-Collars are over rated.
You don't need a X-Ray machine to tell if someones leg is broken or fractured, a tunning fork and a stethoscope work fine.
You can make many medicines, including insulin.
Disposable supplies often aren't, but supplies designed to be reused are better.
Expiration dates, with few exceptions, are artificial and the real shelf life of drugs is much longer. A lot depends on storage conditions, however.
etc.
