Jeff and Evan show you how to use this tourniquet and also behind the scenes of how and why it was created in this instructional video. Jeff has tested the R.A.T.S. Tourniquet numerous times in the field. It was developed to use in real life situations such as under stress and at night. When a person is stressed fine motor skills diminish while gross motor skills become enhanced. When applying a tourniquet like R.A.T.S. you do not need fine motor skills. There is no looping, threading or the like; just wrapping and cleating off. Lack of visibility in the night also is not a problem as this system is simple.
