Pressure Points
A pressure point is a place where pressure can be applied to stop the flow of blood to the limb. This can be used when direct pressure cannot control the bleeding. Here, the artery can be pressed over bony area to stop blood flow beyond that area. For upper limb, pressure point is over arm near the armpit, and for lower limb, it is over the upper part of the thigh near the hip joint.
Tourniquet
Tourniquet is applying pressure by binding with rope or piece of cloth proximal to the wound. It is the last resort to control bleeding. Once a tourniquet is applied, it should not be removed by anyone other than a doctor. The different steps you need to follow while making a tourniquet is shown below.
