Tourniquet: A medical device applied to a limb that can compress a limb with sufficient pressure to stop arterial bleeding.
Marine Tourniquet: A tourniquet made with marine grade materials so that it can maintain efficacy (effectiveness) when exposed to marine environment elements such as saltwater, UV, etc.
According to studies conducted by the U.S. Army Institute of Surgical Research, windlass tourniquets such as the CAT by North American Rescue and others should be kept in the plastic until ready to use to protect the device from the elements 1.
Figure 2: Scuba Diver from Warfighter Scuba applies OMNA Marine Tourniquet during dive.
If you need to have a tourniquet applied before the onset of shock to be effective, you can bleed out in as little as 3 minutes (180 seconds), shock develops once you lose more than 20% of your blood volume, that means you have roughly 36 seconds to get a tourniquet properly applied for it to be successful in lifesaving. Now add the water, are you able to get to the surface, get to a boat or shore, and get a tourniquet on before times up?
