Controlling Nosebleeds
A nosebleed is sudden bleeding from one or both nostrils, and may result from a variety of events: a punch in the nose, breathing dry air, allergies, or for no apparent reason. To stop the flow of blood from a common nosebleed, use these steps:
  1. Sit or stand upright to slow the flow of blood in the veins of the nose. Do not tip your head back.
  2. Pinch your nose with your thumb and forefinger for 10 minutes without relieving pressure. Breathe through your mouth during this time.
  3. If the bleeding continues despite these efforts, consult your doctor or call 911.
