Step-by-Step Guide
-
Step 1: Only apply a CAT on wounds on the arms and legs.
These are areas where bleeding from the wound cannot be controlled by direct pressure.A tourniquet does not work on the wounds on the head, neck, chest or abdomen; never apply a tourniquet on these areas as it can lead to further injury such as nerve damage. -
Step 2: Ask someone at the scene to call Emergency Medical Services.
Call the person at the scene by their full name, if you know the person, and instruct them to call EMS immediately while you apply the CAT on the injured person or on yourself.
If you don’t know anyone at the scene, point at someone close by and instruct them to call EMS.
For example, “You in the black, please call EMS immediately”. , This will prevent the transmission of harmful microorganisms into the wound., You’ll need:
Combat Application Tourniquet
- you can purchase one online or at your nearest medical supply store.
If you do not have one readily available, you can use alternative material like a rope, belt, or elastic bandage.
Two or three sterile dressings or a clean cloth.
Sterile gloves.
Medical tape.
Scissors. , Do this by holding the upper two edges of the package and pulling it sideways to easily open it.
Do not touch its content as this can make it unsterile. , Speak clearly to them and be honest by explaining the procedure will be quite painful.
This will prepare them, and let them know what to expect.
It will also establish trust and cooperation., Doing this will prevent the transmission of harmful microorganisms by creating a physical barrier between your hands and the surface or any fluids it comes in contact with., You want to make sure you can see all of the wound so you know the extent of their injury. , Applying direct firm pressure into the wound without interruption stops bleeding by compressing the sides of the torn blood vessel, thus reducing blood flow.If the sterile dressing or clean cloth is already soaked, get another one and put it on top of the first sterile dressing or clean cloth.
Doing this will help to absorb more blood from the wound. , If bleeding has stopped, get a new sterile dressing or clean cloth and apply it on top of the wound.
Secure the edges with medical tape and use the scissors to cut the tape.
If the bleeding has stopped or appears under control, you do not need to apply a tourniquet. , Keep in mind the use of a CAT should only be used as a last resort because it is a painful and prolonged application that can result in nerve damage. , As the procedure will be a painful one, slow, deep breathing will then slow down their sympathetic nervous system, which is responsible for pain perception.
This will block pain signals travelling to their brain.You can also talk to the person to distract them as you apply the tourniquet. , The constriction caused by the CAT prevents blood from flowing into the wound, thus stopping the bleeding.
Do not place the tourniquet below the injured area since it will not stop the bleeding and may even make it worse. , This should be done the same way you would secure a belt around your waist. , You can twist it counterclockwise or clockwise. , If bleeding from the wound still continues, get another CAT tourniquet and place it 2 inches above the first CAT tourniquet. , The faster help arrives the sooner medical treatment can be given and the less blood from the wound will be lost.
When a tourniquet is in place, it will likely be uncomfortable since the area under pressure.
There may be a heavy grip or tightening feeling around the wound.
This is normal as the tourniquet is trying to prevent further blood loss. , If the injured person cannot take it anymore and is screaming in pain, this may be a sign of compartment syndrome, where increased pressure builds up in the person’s muscles.Adjust the tourniquet slowly while checking to see if there is still any bleeding from the wound.
If there is no bleeding you may loosen the tourniquet but do not remove it.
This is a precautionary measure in case bleeding starts again. , When the self-adhering band on a tourniquet is tightened, pressure is placed at the site of bleeding, specifically in the artery that was injured.
The pressure on the artery stops blood flow and blood loss from the wound., Do not place the tourniquet on minor injuries as it may cause more harm than good due to the lack of blood supply to the lower area of the wound.Heavy bleeding is characterized as excessive and continuous bleeding.
Applying pressure to this injury may have no effect, so you’re only resort is a tourniquet.
Heavy bleeding usually occurs from injured arteries located in the wrist, neck, upper arms and the thighs.
There may also be heavy bleeding from large wounds on a person’s extremities. , If the bleeding does not stop, place a bandage on the wound.
If it still does not stop, then you may use a tourniquet. , Prolonged use of a CAT can lead to nerve damage.If the injured person’s leg or arm was amputated, do not remove or loosen the tourniquet.
Amputation in the legs or arms may cause massive bleeding, so the tourniquet should remain in place., While pain may vary from individual to individual, tourniquets will cause a level pain in the area.
This could be a sharp, dull, throbbing or excruciating pain.
As well, the longer the tourniquet is on, the more intense the pain becomes. , Though tourniquets are easy to use and reusable, they are not cheap.
The estimated cost of a CAT is about $25.So if you don’t want to spend money on a CAT or are in a situation where a CAT is not readily available, you can use alternative or cheaper material like a rope, a cloth, or an elastic bandage. , The most effective way to learn how to correctly apply a tourniquet is to try it on yourself first.
Studies have shown that the incorrect use of the Combat Application Tourniquet can cause death.
So, proper placement and use of the tourniquet is essential to prevent blood loss and death.Take precautions when practicing since this procedure will cut the blood to your extremities.
Do not keep the tourniquet in place for a long time.
