If the bleeding is from a vein, apply it on the opposite side.

It is generally best to apply pressure directly over the wound or on both sides.

The pressure can be made with the thumbs or with the whole hand.
Grasp the part firmly and press very hard, or tie a handkerchief or towel around the wounded part and twist it very tight.

If an arm or limb is the part injured, the person should be made to lie down, and the injured part should be held up.

This is of itself an excellent means of stopping hemorrhage.
