The 8-month-old baby’s nose purring may be caused by dry air that dries out the nasal mucosa and causes secretion blockage to form. Parents can relieve the purring phenomenon by putting vitamin AD drops into the nasal cavity or using a warm wet towel placed near the nasal cavity to make nasal secretions discharge by evaporation of water vapor, thus relieving the nasal blockage. If the baby is suffering from bronchitis or pneumonia causing secretions, the phenomenon of phlegm in the trachea and bronchi needs to be addressed. This can be treated with oral anti-inflammatory or anti-viral medication, as well as oral phlegm-suppressing medication for cough. In order to relieve the phenomenon of blocked nasal secretions, nebulized inhalation treatment can be given. Nebulized inhalation drugs can act directly on the respiratory tract, which can effectively relieve the phenomenon of nose whirring and whistling.
