Most nosebleeds are minor and can be stopped if you apply direct pressure by pinching your nostrils shut for 10 minutes. See how to stop a nosebleed. Bleeding in the back of the nose (posterior epistaxis) may cause a heavy nosebleed that continues after 10 to 20 minutes of home treatment. This type of nosebleed is less common and usually requires medical treatment to stop the bleeding.
Moderate to large amounts of blood flowing continuously from the nose or down the throat despite 10 minutes of direct, continuous pressure to the nose
Bleeding that continues despite 20 minutes of direct, continuous pressure (2 times for 10 minutes each)
If severe bleeding occurs with signs of shock, call911or other emergency services immediately.
More than 3 episodes of small amounts of blood flowing from the nose or down the throat occurring over 24 hours
Bleeding that is controlled by direct, continuous pressure to the nose within 20 minutes (2 times for 10 minutes each)
2 to 3 episodes of mild bleeding in 24 hours
