It is incorrect for patients to tilt their heads up and down when they have nosebleeds. When nosebleeds occur, usually maintaining a normal head position and using both fingers to press on the bilateral nasal flanks for 3-5 minutes, most bleeding located in the front of the nasal cavity can mostly be stopped. Cotton balls can be used for compression, but toilet paper is not recommended because it is difficult to remove when it encounters blood. When a patient with nasal bleeding tilts his head, it can cause blood to flow from the nasopharynx to the mouth, stimulating the oropharynx, leading to nausea and vomiting, which in turn aggravates the nasal bleeding, while nasal bleeding can generally be aggravated with the action of gravity when the head is lowered. For nasal bleeding, cold compresses can be applied to the neck and forehead to reduce blood flow. The diet should be light, with more coarse fiber food, to keep the bowel movement smooth. If the treatment is not good, you need to seek medical attention and fill the nasal cavity in time.
