An unventilated nose with a cold may be caused by pathogenic microorganisms invading the mucous membrane of the upper respiratory tract, resulting in swelling of the nasal mucous membrane and blockage of secretions. Physical therapy, nasal medication and oral medication can be used to help relieve the symptoms. 1. Physical therapy: During colds, it is recommended to pay attention to rest, eat a light diet, increase the amount of water intake, and apply a hot towel to the nose, which can alleviate the symptoms of nasal congestion and make the nose ventilated. 2. Nasal medication: If necessary, you can give topical nasal medication, commonly used clinical drugs, including furosemide nasal drops, which can constrict blood vessels and keep the nasal passages open. 3. Oral medication: If you are sure that your nose is not clearing up due to a cold, you can give anti-cold medication, such as cold and flu clearing heat granules, cold and flu capsules, etc., and you can also combine with antiviral oral solution and other medications. It is recommended to drink more water, rest more, eat a light diet, go to the respiratory medicine department of the hospital if necessary, and give the appropriate medication under the guidance of the doctor, and follow the doctor’s instructions for medication.
