Bleeding from a large cut or laceration can be brisk if one of the larger veins or arteries is cut. The best generally applicable method for control of such bleeding is to exert firm pressure, using a cloth compress, against the area.
In an emergency one can employ a wad of facial tissue, a handkerchief, towel, shirt, or a pillowcase suitably folded on itself so as to make the compress. Press it against the bleeding site, and if the cut is on a limb, elevate the limb, for this too diminishes bleeding. Maintain pressure for five to ten minutes.
One may then lift part of the compress to judge whether the bleeding has come under control. If it has not, pressure can be maintained for a longer period or even indefinitely if necessary.
