Another Chance Tourniquet was formed in Michigan in 2013. Founder/CEO, Alice M. Brown, made a comment that her knee re-trainer would make a better tourniquet than what the military currently uses. She was asked to prove it and she did!
Another Chance Tourniquet, has a line of tourniquets categorized for different needs.
According to DoD, the time to permanent damage is 78 minutes up to 2 hours!
Another Chance Tourniquets are categorized by:
1. Even Pressure MB or LT, metal spring buckle, or light, is designed where there is possibility of limb amputation and best for short transport, under 2 hours, as in the city or urban areas or where transportation to medical help is relatively short.
2. Dual Pressure, DP, is not best for amputation as it allows some deep circulation and is best for use in rural areas such as hiking, hunting, horseback riding, farming, and where transportation is not readily available and time from application to removal of tourniquet is expected to be close to or more than 78 minutes or up to 2 hours.
A person with significant bleeding will die unless bleeding is stopped. All tourniquets have the potential to save lives, but they must be used timely, correctly and be available when/where needed. Then get the bleeding person to medical help ASAP for proper removal and medical care.
How Does a Tourniquet Work?
The body vessels from the heart to the limbs start out as one artery and one vein, then split into deep and superficial vessels. This split occurs mid upper arm or in the leg or in the hip. Placing a tourniquet 2-3 inches above the bleed, but below the split, is essential to stopping the bleed and gives best chance for the deep circulation to preserve limb tissues below the tourniquet. Placing tourniquet below the joint on lower section of the limb, is unable to stop the bleed as the two bones of lower limb protect the vessels. Bones would have to break before bleeding is stopped.
All tourniquets have the potential to save lives by preventing "bleeding out".
A dual pressure tourniquet has the potential to stop the major bleed if placed properly, on inside of the upper section of the limb, where the vessels are more superficial, above the joint, as it may still allow deep circulation. This is best used when transportation time to medical removal is expected to be long.
Even pressure tourniquets stop all blood flow and can be used for short transportation times.
Normally, circulation removes toxins slowly so the body can detoxify and remove them, while bringing nutrients and oxygen to the cells to keep them alive. Slow removal of toxins has the potential to prevent or slow development of toxic shock, which is a complication of tourniquet use when the tourniquet is released, toxins are also released which may overwhelm the bodies ability to remove them.
Diagram below shows the main splits of circulation. Black bars show the best locations of tourniquet placement when transportation time is expected to be long. If transportation is expected to be short, place the tourniquet as high up on the limb as you are able. The red circles with lines through them, show the places not to apply a tourniquet as it will be ineffective and just waste valuable resourc
