Capillary bleeding occurs only for superficial wounds, the blood is from the wound drops. Since blood loss during such a wounding slight, the blood is easily stopped with an overlay of clean gauze bandages pre-treated with hydrogen peroxide. On top of the gauze, place a layer of cotton wool and tie a bandage. If not at hand a bandage and gauze bandage bleeding clean handkerchief. Don't use fluffy material as it is fraught with contamination of the wound (for the same reason, put cotton wool on a degloving injury).
With deeper wounds (stab and cut) occurring in venous bleeding, while you can observe the abundant discharge of dark red blood.

Stop the flow of blood to the wounded place by clamping the artery with your finger just above the injury. But this measure is temporary. Clamp the artery until then, until you are ready and do not apply a compression bandage. In some cases it is necessary to apply a tourniquet.
