One of my favorite activities is to walk the woods.
I especially like to explore off the trail. I have some rock climbing experience, so I can be more daring than some people I know.
But those rocks can be sharp and all it would take is one slip to cause a traumatic enough wound for me to bleed to death without expeditious care.
May is Stop the Bleed Month.
Even outside the wild, traumatic bleeding injuries are one of the highest causes of death in the United States.
Hemorraghing, or bleeding profusely, can cause someone to bleed to death in minutes.
EMTs can’t get to you within minutes if you’re miles into the wilderness.
Do you know how to stop traumatic bleeding by yourself?
Types of Bleeding
All major hemorrhages are dangerous, but some are lethal more quickly than others.
Traumatic wounds will be either arterial or venous. You want to stop it in both cases but some techniques won’t work with the wrong type of bleeding.
Arterial
Your heart uses arteries to supply fresh blood to your body.
This type of blood will be a bright red and come out rapidly, often spurting along with the heartbeat.
Arterial bleeds are the most dangerous because they can cause your heart to push out all of your blood in minutes.
Or seconds, in the case of major arteries such as the abdominal aorta.
Venous
Veins are used to bring old blood back to the heart.
This type of blood will be a darker red (no, not blue!), and will be a constant, slower flow.
A traumatic injury to a vein can still cause death, but it will take a lot longer than an arterial cut.
Venous exsanguination can take hours, but it’s still a good idea to stop the bleeding as soon as possible.
Capillary
The small blood vessels near the surface of your skin are called capillaries.
Capillary bleeds will be bright and bleed fast, but won’t be high in volume and often clots faster than other wounds.
Unless you have hemophilia, a capillary bleed is rarely a life-threatening event, though they can be very alarming.

First Steps
Once a traumatic event has happened and you see blood spurting all over the place, it’s time to act.

First of all, sit the victim down, whether it’s you or someone else. Blood loss can cause weakness and fainting, so you don’t want them to fall over and hit their head.
Then, talk.
Explain what you’re seeing and what you’re about to do. This will build up trust and provide comfort to the patient (even yourself!).
But don’t slow down the actual first-aid in order to comfort the victim.
Get out your medical gear. Then, get yourself sanitized if possible.
This means putting on rubber gloves or using hand sanitizer, if possible.
If that would slow you down, though, proceed immediately to stopping the bleeding. Stopping the bleeding is more important than preventing infection.
Ways to Stop Bleeding
A serious wound can cause death by exsanguination in minutes, whether arterial or venous.
This means that objective #1 is to stop the bleeding, by all means.
The following text, images, and videos are great resources to learn how to stop the bleed. But they are no replacement for hands-on experience.
So, I encourage you to take a course on bleeding control.
Until then, here’s what you can do to stop bleeding:
Apply Direct Pressure

The most effective and safest way to slow bleeding is to apply direct pressure on the wound.
This cuts off the blood vessels and gives you time to dress the wound.
Hand pressure is recommended, especially when holding gauze or cloth. However, this may not be possible if you’re alone in the woods.
In this case, use something else to apply pressure.
Your knee can be surprisingly useful for applying pressure. You can also hold the limb against another part of your body, especially if you are able to jam the far side against a rock, tree, or the ground. so you can put your body weight against the wound.
Slowing the blood flow this way will give the blood more time to clot before you bleed to death!
Use Digital Ligation
Sometimes, direct pressure outside the wound is not enough and you need to reach into the wound with your fingers to apply pressure directly to the blood vessels.
This is called digital ligation.
It’s best done when you have multiple sets of hands as removing the fingers can cause the blood to flow again.
Block Pressure Points
If you can’t stop the blood flow directly, then look up the body.
Pressure points are areas on the body where the blood vessels are close to the surface. If you know how to take a pulse, then you know several pressure points.
Apply pressure to these places to slow down blood flow and increase clotting, IF it’s an arterial bleed.
If you’re alone, lash a stick to a pressure point.
If the wound is on part of the body supplied by several arteries then these pressure points are less helpful.
Pressure points include:
- Temples
- The sides of your neck
- Above the clavicles
- Inside your upper arm
- Crook of your elbow
- Wrist
- Groin
- Inside your knee
- Ankle
If your head is bleeding then don’t hold down both pressure points! You still need blood flow to your brain!
Elevation
Raising your the wound above your heart won’t stop the bleeding by itself but can work in conjunction with other methods to make them more effective.
Your heart can’t pump blood up as well as it can pump blood down, so keep the bleeding area higher than your heart.
Apply a Tourniquet
Tourniquets can be a touchy subject and many people say they are harmful and will kill your limbs in hours.

Due to battlefield research, we know that tourniquets are both more efficacious and less dangerous than previously thought.
You still don’t want to wear a tourniquet for more six hours, but if the choice is between exsanguination or amputation, trade your limb for your life.
Use tourniquets under two circumstances:
- When you can’t stop arterial bleeding using other methods
- If you don’t have time to stop the bleeding before you need to move, such as during combat, a flood, or another time-sensitive emergency
I’d recommend the C.A.T. Gen 7 tourniquet. It’s tested in combat and easily applied with one hand.
You can also craft your own TQ in the woods, which I’ll cover later.
To use a tourniquet, position it on the limb between the wound in your heart, close the loop so you are unable to get three fingertips underneath the tourniquet, then twist the windlass until the bleeding has stopped.
If it hurts more than the wound, congratulations! You’ve done it right.
There are two schools of thought as to where to place the tourniquet:
- Shortly above the wound
- High and tight
Let’s look at those in detail:
Above the Wound
The “civilian” position to apply the tourniquet is 2-4 inches above the wound.
You don’t need to break out the ruler to get this right. Just put the TQ three fingers above the wound.
If you’re hemorrhaging from your forearm, put the TQ above your elbow.
Never put the tourniquet on a joint and never put the tourniquet below the wound! It should always be between the wound and your heart.
High and Tight
The “military” place to apply the tourniquet is very high on the limb.
Right next to your armpit for arm wounds and right next to the groin for leg wounds.
This is because stopping the bleeding is more important than finding the proper position.
High and Tight is also good for nasty gashes with damage that’s traveled under the skin, because sometimes blood vessels are damaged several inches above the visually damaged area.

Record the Application Time
The medical professionals will need to know how long the tourniquet has been on.
So, take a sharpie, and write the application time on the victim’s face, along with a large T.
If the victim has lots of hair then write the time on the neck or anywhere else that is conspicuous.
Releasing the Tourniquet
Older wisdom held that tourniquets should be released every 15 minutes or so for one minute to keep blood flowing to the extremity, preventing cellular death.
We now know that your limb can survive without blood for up to 6 hours.
Releasing the tourniquet will cause more bleeding and can damage the TQ and make it lose efficacy.
So, if you can make it to help before six hours, it’s safer to leave the tourniquet on.
It may even be safer to leave it on for longer because, again, it’s better to lose a limb than lose your life.
Pack the Wound
If the bleeding won’t respond to direct pressure and a tourniquet can’t be used, such as a deep torso wound, pack the wound and apply a pressure dressing.
Fill the wound with sterile gauze (or an alternative, see Field Expedient Medical Supplies below) and hold it tightly in place with a bandage if possible.

Make sure that the packing material pushes up against the blood vessels!
The idea is to apply pressure (sort of like digital ligation) to slow the bleeding and hold blood against the vessels so they can more easily clot. You can’t do this if the wound is loosely packed!
If you don’t have any medical bandages then wrap and tie a strip of clothing or a bandana over the dressing.
Don’t replace bloody dressing! Apply more as it gets soaked through or you’ll interrupt the clotting process.
Wound Dressing
Now that the wound isn’t bleeding as much, it’s time to do what you can to prevent infection, prevent further damage, and even hasten the healing process.
Clean the Wound
The wild is a dirty place, filled with bacteria and other little critters that see your exposed flesh as the perfect place to live.
Infections are no joke, so if it’s possible, clean your wound.
The easiest way to do this is to flush the wound with safe water. This is called irrigation.
Pressurized sterile saline water is best, but that’s in short supply in the woods.
Boiled then cooled water can also be used. Also, filtered water.
Don’t wash a wound directly with “raw” water, even if it’s from a clear, moving river. That water will still have contaminants.
Do not use iodine or hydrogen peroxide unless absolutely necessary. They can irritate the exposed flesh and cause further damage.
Protect the Wound
Once you’ve slowed or stopped the bleeding and have cleaned the wound, if possible, it’s time to protect it from further harm.
Apply antibiotic cream, if you have any.
Then cover it with a clean bandage or sterilized cloth.
If the wound does get infected, there are still steps you can take to survive. You can find those here.
Close the Wound
If you’ve experienced a cut that didn’t tear out a chunk of your skin then you may be able to close the wound.
This will maximize healing and minimize scarring, but only do it if you can bring the separated pieces of skin and underlying flesh together without stretching.
If you can, use medical tape to close the cut.
Use two pieces, one on either side. Grasp them both and pull them to the opposite side so they pull the cut shut.
Duct tape can also
