Spotter Up: The EDC Tourniquet

Eugene Nielsen at Spotter Up has a pretty comprehensive article on The EDC Tourniquet.

According to published research, reported in the October 2017 issue of the Journal of the American Medical Association (JAMA)), the average response time in the US from the time of a 911 call to arrival of EMS on scene was seven minutes. This increased to more than 14 minutes in rural settings. A person can bleed out from a severed femoral artery in less than five minutes. You do the math.

In an active shooter or terrorist incident, emergency personnel won’t reach victims until the threat has been neutralized. During the Paris attacks on 13 November 2015, it was over 160 minutes from the time the terrorists fired the first shots in the Bataclan theater until the responding emergency personnel were able to reach those inside the venue.

The reality is that you’re going to be your own first responder. Bystanders will always be first on the scene, whether it be terrorism or other criminal act or an accident. In the Boston Marathon bombing on 15 April 2013, bystanders employed improvised tourniquets to save lives. Time consuming and inefficient, but it was all that they had. Don’t plan to improvise if the need arises. Always have a real tourniquet.

Data from the Boston Marathon Bombing found that six of the rubber and improvised type tourniquets had to be subsequently replaced with C-A-T® tourniquets. Additionally, the most common EMS tourniquet on scene consisted of rubber tubing and a Kelly clamp.

Roughly 80% of combat deaths and 50% of civilian trauma deaths are attributable to hemorrhage. It’s the most preventable cause of death in compressible injuries. The proper use of tourniquets saves lives.

Hypovolemic Shock

Time is of the essence. Hypovolemic shock occurs where there is an acute fluid or blood loss in the body. It’s a life-threatening emergency. Hypovolemic shock is most often secondary to rapid blood loss (hemorrhagic shock). It causes inability of the heart to pump the essential blood needed to the body, resulting in multiple organ failure due to inadequate cellular oxygenation. There are four stages of hypovolemic shock.

Stopping the blood loss before patient goes into Stage II shock, ie., blood volume loss up to 15% (~750 mL), keeps survivability at around 94%. If blood loss continues and the patient is in Stage II (30% or ~1500 ml) or greater, the survivability goes down to 14%, without any blood being administered. These figures are based on a US Army Institute of Surgical Research (USAISR) study conducted in 2006 and 2007.

Tourniquets

While I recommend that everyone carry a trauma kit, a tourniquet (and gloves) needs to become part of your everyday carry (EDC) at the at the very minimum. Tourniquets have emerged as the standard of care in the tactical environment due to their ease of use, rapid application, and complete stoppage of blood loss. Current protocol considers the tourniquet an initial lifesaving intervention to control massive hemorrhage from an extremity.

The old dogma of “save a life, lose a limb” has been proven to be false. A tourniquet can safely remain in place for up to two hours. Thousands of combat veterans are walking around today with all their limbs because their lives were saved by tourniquet use.

The use of tourniquets on the battlefield isn’t new. As far back as Alexander the Great’s military campaigns in the fourth century BC, tourniquets were used to staunch the bleeding of wounded soldiers. The term “tourniquet” dates from the 17th century and originated from the French “tourner” meaning “to turn”. .

Tourniquets lost popularity after the US Civil War, having been blamed for complications that resulted in amputation. This misunderstanding has unfortunately persisted, especially as it pertains to tourniquet use in civilian settings.

Although there have been several studies in the past that have looked at tourniquet use in civilian settings, the survival benefit for patients has been unclear. However, new research shows that for civilian patients with peripheral vascular injury, prehospital tourniquet use is associated with dramatically improved odds of survival.

The study, titled “Civilian Prehospital Tourniquet Use Is Associated with Improved Survival in Patients with Peripheral Vascular Injury,” was published 29 March 2018 and reported in the May 2018 issue of the Journal of the American College of Surgeons (JACS). This study was a multi-institutional retrospective review of all patients sustaining peripheral vascular injuries admitted to all 11 urban Level I trauma centers in the state of Texas from January 2011 to December 2016.

The study found that “Although still underused, civilian prehospital tourniquet application was independently associated with a 6-fold mortality reduction in patients with peripheral vascular injuries. More aggressive prehospital application of extremity tourniquets in civilian trauma patients with extremity hemorrhage and traumatic amputation is warranted.” Simply put, tourniquets save lives.

Popular commercial tourniquets include the Combat Application Tourniquet® (C-A-T®), SOF® Tourniquet, RevMedx® TX® Series Ratcheting Medical Tourniquet -Tactical™ (RMT-T™), SAM Extremity Tourniquet (SAM-XT™), Tactical Mechanical Tourniquet™ (TMT™), SWAT-T® and Rapid Application Tourniquet System®® (R.A.T.S.®) / Rapid Tourniquet. Each has its pros and cons. All are capable of occluding blood flow when properly applied.

As of this writing, the C-A-T, RMT-T, SAM-XT, SOF Tourniquet (SOFTT-W), TMT and TX Series (TX2 and TX3) are  the only US military Committee on Tactical Combat Casualty Care (CoTCCC) recommended non-pneumatic limb tourniquets. It’s important to keep in mind that the CoTCCC, a division of the DoD Joint Trauma System, is looking at tourniquets for use on adults in combat by trained military personnel. not for use by civilians with limited training or for use on children.

The C-A-T, RMT-T, SAM-XT, SOF Tourniquet, TMT and TX Series are windless/ratcheting tourniquets. The SWAT-T (Stretch, Wrap and Tuck Tourniquet®) and R.A.T.S. are elastic wrap tourniquets.

A plus to elastic wrap tourniquets is that they pack down into a significantly smaller size, making them easier to carry. They’re also considerably less expensive than windless/ratcheting tourniquets. On the downside, elastic wrap tourniquets require a wider range of motion to apply. The latter can make self-application more difficult.

The SWAT-T and R.A.T.S. can be be employed for higher axillary and groin applications than windless tourniquets. They may also be employed for pediatric and K-9 applications, where standard windlass tourniquets cannot. A study of commercial tourniquets conducted in Israel, and reported in a paper submitted to the 2018 NAEMSP Scientific Assembly, found that the SWAT-T and R.A.T.S. were the best tourniquets for use on children.

It should be noted that North American Rescue states that the C-A-T has been shown to be effective on limbs as small as five inches in circumference. It should also be noted that the TX Series ratcheting tourniquet is available in a pediatric model designed specifically for children.

The SWAT-T is a versatile medical multi-tool that may be employed not only as a tourniquet, but also as pressure dressing, occlusive device, elastic bandage, sling and swathe, used to secure a splint, and more. If the SWAT-T is employed as a pressure bandage or dressing, it’s important to check for a distal pulse after application. Although not a CoTCCC-recommended tourniquet, the SWAT-T has been the subject of several studies which demonstrated it’s efficacy.

PHLster Flatpack Tourniquet Carrier

No tourniquet does you any good if you don’t have it with you when you need it. I have found the PHLster Flatpack® Tourniquet Carrier from PHLster Holsters to be a great, low-profile way to EDC a windlass tourniquet for easy, one-hand deployment. Designed for versatility, it allows you to carry a folded and staged windlass tourniquet on your belt, in a pocket or with MALICE CLIPS® for MOLLE/PALS mounting..

Training

Having the necessary tools is only part of the equation. Equipment is only as good as your training. Basic emergency medical training should cover the entire spectrum of lifesaving skills. And like shooting, they’re perishable skills.

Emergency medical training should be part of the basic skill sets of every firearms owner. In fact, it should be part of the basic skill sets of everyone. The time to learn isn’t when someone is bleeding out.

The National Association of Emergency Medical Technicians (NAEMT) and STOP THE BLEED® are excellent resources that can direct you to courses in your area. Dark Angel Medical offers a free online introductory course designed to teach the basics of bleeding control.

Hemorrhage is the most preventable cause of death in compressible injuries. It accounts for approximately 80% of battlefield deaths and 50% of civilian trauma deaths.

Dark Angel Medical also offers an outstanding two-day Direct Action Response Training (D.A.R.T.) course at various locations around the country. All participants receive BCON (Bleeding Control) certification from the American College of Surgeons. It also provides 16 hours of CEU’s, per CECBEMS, to NREMT EMT-Basics/Advanced and Paramedics. I have taken the D.A.R.T. course and highly recommend it. Dark Angel Medical is also a great source for trauma kits and components. I have taken the course and highly recommend it. Idid an article on the D.A.R.T. course recently for Spotter Up.

The online learning platform Deployed Medicine is also valuable resource. It’s used by the Defense Health Agency (DHA) “to trial new innovative learning models aimed at improving readiness and performance of deployed military medical personnel.” Learning assets include the standardized Tactical Combat Casualty Care All Service Members (TCCC ASM) Course curriculum developed by the Joint Trauma System, which is part of the DHA. You don’t have to be a member of the military to take advantage of its resources.

Some Final Thoughts

Preparedness requires the proper mindset, training, and tools. It doesn’t just happen. It’s a way of life and takes some effort. And it’s about preparing for possibilities, not just probabilities.

Carry a proven tourniquet. Not all tourniquets are created equal. I recommend carrying at least two tourniquets. This will leverage your capability. I carry a C-A-T as my primary EDC tourniquet and a SWAT-T as my secondary/backup tourniquet

Buy from a reputable source. If you try to save a few bucks you may wind up with poorly made counterfeit. Counterfeit tourniquets are a growing problem. They can cost lives. The life you save may be your own or that of a loved one.

Practice with the tourniquet in situations that are similar you may encounter. Get a spare/training tourniquet for this purpose. Don’t use the actual tourniquet that you will be counting on in an emergency. Practice both strong and support side applications.

Spotter Up: Homestead Indoor Gardening

In this post at Spotter Up, Alaskan homesteader David Donchess talks about some food plants that he grows indoors. For people in a preparedness mindset, having food through a long winter can be a big concern. David mentions growing potatoes in a plastic bin indoors to provide food throughout the winter among others. Homestead Indoor Gardening: Plants To Grow

Ever since I moved up to Alaska with my wife, we have tried to be more self sufficient. We have really been drawn into growing our own food, to include livestock. The challenge for us in Alaska is keeping our plants and livestock alive during the winter. The summers churn out many world record sized crops due to the extremely long and warm days. Winter, on the other hand, produces the shortest(4-5 hours of sun) and coldest(-30 to -40) days. The harsh winters here can kill most types of perennials if they are not bred to handle cold down to -50. For this reason, indoor gardening is probably your best bet for continuing production of certain plants like leafy greens and things like strawberries and peppers. For this article, I am just going to talk about some of the plants I have in my indoor greenroom and why I grow them.

THE FOCUS

When we start talking about indoor plant growing, we have to keep in mind that the point is to have the ability to be mostly self-sufficient. The reason for growing plants indoors at my house is not to have something nice to look at, but rather to have a healthy variety of foods to eat and cook with. The main focus, due to limited space, should be to grow plants that are nutrient rich and will give you the best return for your efforts. But don’t forget that some nutrients you need cannot be found in just one plant. You will need to do your research and find a variety of foods that give you a decent return in vitamins, minerals, and macro nutrients.

For my plant selection, I have a few plants that offer the same return in certain nutrients, but lead in one area over the others. Then I have certain plants that are just more versatile and can be used in more ways and in more dishes than others. The choice is yours, but I have spent alot of time deciding what plants are worth the investment. Now keep in mind that this is not an indoor garden that is designed to provide everything during the apocalypse. If that were the case, perhaps we would want to simplify the number of plants we have to a short list that will allow us to minimize the need for water and light.

This specific selection of plants require varying ranges of attention, and it is all based on my abilities, space, and the time I am willing to invest in these plants. Each person will have different capabilities, space, funds, and time, which will determine what they grow indoors…

There are vegetables that I like to grow in order to provide a more diverse and balanced nutrient return, while also helping enhance the flavor of your meals. These veggies offer things that you may not be able to get from leafy greens like calories, protein, and higher concentrations of certain nutrients. Here is a list of the vegetables I like to grow and why.

-Broccoli: This vegetable is a powerhouse for sure. Raw, it has a higher concentration of vitamin C than an orange, and about as much calcium as whole milk. The plant can be a bit difficult to get control of since you have to trim the florets before they bloom. But if you take care of your broccoli plants, they will produce for you over and over again with increasing return as time goes on.

-Carrots: This veggie is one of the more versatile since it can be prepared and consumed in pretty much any way that you can imagine. Just a little bit of carrots can easily provide a huge amount of vitamin A to your diet. It takes some patience to get them to harvest. You can actually reuse the carrot heads to make more carrots, making this a somewhat renewable vegetable.

-Bell Peppers: I like growing these because they add a good deal of texture to my meals. If I am making burritos or a stir-fry, you bet that Bell Peppers are going to be included. They give a decent return in vitamin C, but not much of anything else. For the most part, the plants are easy to maintain and grow indoors as long as you provide a steady temperature and don’t let the soil get too wet…

Potatoes are a big thing for my household to the point that I grow them indoors during the winter in big storage bins. They take some time to grow to maturity, but they offer so much in terms of calories and just energy overall. They are very filling and you can add them to pretty much anything. They are relatively maintenance-free except for periodic watering, and they give back alot in return…
