2. Hold the loose end with the left hand and catch it with two or three turns of the bandage before beginning to put on the bandage. Never have more than four or five inches of the bandage unrolled at once. 3. Be careful to have the same pressure from every turn of the bandage. This is most important if the bandage is to stay on and be comfortable and not interfere with the circulation of the blood. Judgment of the pressure is only acquired by practice, and therefore you should practice enough to acquire this before the real emergency happens. 4. Do not bandage too tightly. Blueness of the skin above or below the bandage always means the bandage must be loosened. Remember in applying a bandage immediately after an injury that considerable swelling may occur later, and apply your bandage more loosely than if bandaging after the swelling has gone down. Always loosen a bandage that is tight enough to cause pain or blueness. 5. Bandage from below upward. That is, from the tip of a finger or toe toward the hand or foot. From the hand or foot toward the shoulder or groin. This is in the general direction of the return of the circulation. 6. Bandage over a splint and not under it. 7. Bandage arms, legs, fingers, etc., in the position the patient is to keep the part in when the bandaging is completed. For instance, bend the elbow to a right angle before putting on the arm bandage. This will be more comfortable for the patient, allowing him to carry the arm easily in a sling and also permit him to use the hand to some extent if the nature of the injury will permit. In bandaging a leg both above and below the knee, the bandage must be put on with a view to the necessary bending of the knee in walking and sitting, if the patient is expected to use the leg. 8. Never apply a wet bandage, as you cannot judge of just how much pressure will be exerted when the bandage dries, because of the shrinkage of cloth with drying; much greater in some cloth than in others. Kinds of roller bandages: 1. Circular for parts uniform in size, as the body. 2. Spiral for conical surfaces, as fingers or toes. 3. Reverse for more conical surfaces, as arms and legs. _Circular Bandages_--Any part of the body which is of uniform size may be covered with a circular bandage. Each turn covers about two-thirds of the previous turn. This holds each turn firmly and prevents slipping and exposing the dressing or wound underneath. Bandage in general direction of the return of the blood to the heart. Fasten the bandage with a strip of adhesive plaster or safety pin. If there is possibility of restlessness or much activity on the part of the patient, it is best to run several narrow strips of adhesive plaster along the whole width of the bandage when finished to prevent possible slipping of the turns of the bandage when the muscles move under it with the activity of the patient. This is especially true of a body bandage.
