For patients with bronchial asthma, nebulization treatment is useful during an asthma attack. During an attack, symptoms such as wheezing and difficulty breathing tend to occur. Typically, nebulizing corticosteroids or bronchodilators can have anti-inflammatory, antispasmodic, and asthma-relieving effects, thus improving symptoms like breathing difficulties in asthma patients. Moreover, the method of nebulized inhalation can take effect quickly, swiftly alleviating the patient's symptoms.
