To stop nosebleed, squeeze nostrils and lilt head backward and upward.

Epistaxis is defined as any bleeding from the nose.  Most nosebleeds stop after a few minutes of pressure against the bony cartilage that forms the midline of the nose.  To stop nosebleeds, apply pressure to both nostrils by squeezing the upper part of nose firmly between your thumb and index finger.  Sit with upper body titled forward and head downward, not tilting backward and looking upward.  This way the blood will drain out of the nose rather than flow back in the throat where it may cause choking.  Ice or cold compress can be applied on the forehead, upper part of the nose and the upper back of the neck. If bleeding is profuse, pack nostrils with gauze or a strip of clean cloth, not tissue or cotton balls.  Avoid removing the packing for several hours.  Go to the emergency room or doctor if bleeding persists, if the bleeding is caused by head or nose injury, or if the patient has a history of high blood pressure.
