Lethal Strike Video
Video one has some bad acting. If you can get past that the info is good to know. Videos two and three I found really good for explaining high pressure injection injurys. Basically what I learned was that if there is any possibility of an high pressure injection injury it should be treated immediately and that you should go to a major hospital with a had sergeant (preferred), because you will need surgery. The longer it takes for the injury to get treated, the more chance of more amputation.
