Simple nosebleeds are relatively common in life and can usually be stopped in 3-5 minutes, but the site and cause of nosebleeds vary, and the time to stop bleeding will change accordingly. If it is a simple ruptured capillary bleeding in the nasal mucosa, the bleeding is not large and normally stops in 3-5 minutes. If the bleeding is from small arteries or veins in the nasal mucosa, the bleeding speed may be faster and emergency compression is needed to stop the bleeding. If the nasal cavity has a large blood vessel rupture and still bleeds more than once after taking measures, it is necessary to go to the ENT department or rhinology department of the hospital to deal with the bleeding situation, which can be improved in 2-3 days by filling and compressing with oil gauze or expanding sponges; it is also possible to find the bleeding point under the nasal endoscope and adopt the treatment of bipolar electrocoagulation under the mirror to stop the bleeding. In addition, when bleeding is large, do not tilt your head backward to avoid blood entering the stomach easily causing nausea and vomiting, or blood accidentally entering the trachea easily triggering choking and suffocation. Avoid picking nose in daily life and eating less spicy and stimulating food to avoid aggravating nasal inflammation by fire.
