If the nose is dry and bleeding, first of all, local pressure can be given in an emergency to stop the bleeding by compressing the blood vessels, but generally it is clear that the nose is caused by dryness, it is necessary to give local application of moistening drugs, such as the application of ointment and oil, to keep the nasal mucosa moist. Because the nasal mucosa inhales gas and plays the role of filtering and heating and humidifying, if the external environment is dry, the temperature is relatively high and the air humidity is relatively small, it increases the absorption of moisture from the inhaled gas to the nasal mucosa, so it is most important to keep the local humidity. If the dryness is caused by inflammation or the nasal cavity is dry due to certain diseases, it needs to be treated for the disease, such as dry syndrome, which is an immune disease, and it needs to be treated for dry syndrome, in order to completely treat nasal bleeding.
