Bleeding using pressure points is a very good was of possibly saving a life. When someone is bleeding uncontrollably, he can bleed to death in minutes or seconds. This can occur long before medical help arrives. When you apply pressure to pressure points involving blood flow, you can slow the bleeding and keep the victim alive until medical professionals arrive
Identify the area of the body that is bleeding and find the corresponding pressure point that will control the bleeding. Each part of the body has a major artery and vein feeding it blood. Look for it. Sometimes you can see a blue vein indicating where it is. Otherwise, feel for a pulse at each pressure point. This will indicate that you are pressing the right point.
If the bleeding is from the neck, press the point on the side between the Adam's Apple and neck muscles. This is where the carotid artery and jugular vein---which supply blood to the brain---are located. Stopping bleeding from here is a matter of life and death.
If the bleeding is from the groin or thighs, press the point on the femoral artery. You find it along the bikini line half way between the hip and the groin. A lot of blood flows through the femoral artery to supply oxygen to the legs. You will need to apply a considerable amount of pressure to stop the blood flow. Have the bleeding person lie down and press downward with your entire hand.
