About Tourniquets.

What’s a Tourniquet?

A Tourniquet is a device used for constricting or halting the flow of blood through a vein or artery, normally can be done using the right knowledge and equipment from primitive to even tactical items specifically created to help effectively compress a limb.

How To Apply?

Some tourniquets have specifical instructions for applying them proficiently and efficiently. Typically though, a tourniquet can be applied by tieing the tourniquet device around the injured leg or arm, several inches above the injury going towards the heart. When the injury is below the elbow or knee, you may need to tie it above the joint, you can use a common square knot, still placing it on the part closer to the heart on the wounded limb not on the other side away from the heart on the injured area. If done right, it will cut off the blood flow stopping the victim from bleeding out. If possible, as another way to check if you applied the tourniquet right, you can check for a pulse below the tourniquet; no pulse should exist there. 

When it’s needed?

Typically after looking at a wounded limb and thinking somewhere along the lines of, “holy s… that’s a lot of blood!” But, mainly when you or multiple victims have uncontrollable bleeding coming from a partially amputated or amputated arm or leg that can no longer be effectively hindered by using bleeding control methods, such as applying pressure and bandges to the wound. Just remember that every second can count when it comes to saving lives especially if there is someone bleeding out heavily and multiple victims.
