A nosebleed is severe if:

• You have moderate to large amounts of blood even after you have pinched the nose shut for 10 minutes.
• Your nose is still bleeding even after 15 full minutes of direct pressure.

• The nose bleeds small amounts of blood more than 3 times in 24 hours.

A nosebleed is mild if:

• You have a little bleeding, but direct pressure stops it within 10 minutes.
• The nose bleeds no more than 3 times in 24 hours, and each time the bleeding is mild.
