In general, patients need to do the second nebulization about 12 hours apart, the specific interval can be adjusted according to the patient’s condition and needs. Nebulization mainly involves putting glucocorticoids and bronchodilators into a nebulizer for inhalation treatment, and the frequency of the specific medication should be determined according to the patient’s condition. In general, patients with bronchopneumonia should do nebulizer inhalation treatment at an interval of about 12 hours, which may be difficult to implement for outpatients, or they can do a second nebulizer treatment at an interval of about 6-8 hours. For patients with acute asthma attacks, in order to relieve the patient’s symptoms as soon as possible, nebulization can be done once at an interval of half an hour, and 2-3 times in a row. In addition, patients should rinse their mouths after nebulizer treatment to avoid oral infection. At the same time, nebulizer treatment must be carried out under the guidance of a professional doctor, and if there is a nebulizer at home, nebulizer treatment should not be carried out with medication without authorization.
