Explanation:

If a special tourniquet is not available, such as those that come in first aid kits, it is possible to improvise using soft, strong and flexible material, such as gauze, bandage, clothing or handkerchiefs, in order not to cause damage to the skin, making sure that the tourniquet has a minimum width of one inch to tighten.

C. Blood pressure cuff.

A blood pressure cuff is used to take blood pressure. The cuff has an inflatable rubber bladder that is fastened around the arm.
