Nosebleed, First Aid 

Seek emergency medical care if a neck injury or serious head injury is suspected.

Get medical help if the person bleeds or bruises easily, is on any blood-thinning medication (eg, large does of aspirin, warfarin [Coumadin®]), has high blood pressure, or if the nosebleed continues after 30 minutes of the self-care measures discussed in the First Aid Guide.

If the nosebleed is occurring in the back of the nose, into the throat, bleeding will be hard to stop and the person should likely seek medical care.

If you suspect a nosebleed caused by a broken nose, seek medical care; a broken nose that heals improperly can affect breathing and appearance.

If the nosebleed is caused by an object lodged in the nose and it cannot be removed by the the self-care measures discussed in the First Aid Guide, seek medical care.
