I have some that I have placed into my numerous personal FAKs; however, I have yet to use it as the standard direct pressure, pressure bandage and elevation have been adequate to date.

I have serious doubts that any EMS jurisdiction in the US has it deployed into routine (accepted) use to date. Most EMS systems will rely upon the basics, both for liability issues as well as cost. I doubt, that here in Maryland it would ever become Standard of Care use.
