These higher or deeper nosebleeds may be harder to control. Occasionally, nosebleeds may indicate other disorders such as bleeding disorders , hypertension , or arteriosclerosis . Most nosebleeds begin on the septum, the midline, vertical cartilage that separates the nasal chambers and is lined with fragile blood vessels. This form of nosebleed is not serious and is usually easy to stop. Recurrent nosebleeds may be a symptom of an underlying disorder such as high blood pressure , taking large doses of aspirin or blood thinning medication, allergies , a bleeding disorder , or a tumor of the nose or sinuses.
Most nosebleeds come from blood vessels in the front of the nose.
Calm and reassure the victim. Encourage breathing through the mouth. Have the victim sit down and lean forward slightly. This will help keep blood from going down the back of their throat. Check to see if there is an object in the victim's nose and remove it if necessary.
