This can be done as follows:
The easiest method, but quite effective: with a head up upside down, put a cold towel (moisten in water) or any cold item on the nose bridge. If you still cool the occipital part of the head, then the blood stop will pass very quickly. To do this, you need to attach ice, a bottle of cold water or a fan to the back of the head. The vessels from the cold are narrowed, even severe bleeding will stop.
