Bronchial asthma is a disease characterized by breathlessness, chest tightness, rapid breathing, and coughing, caused by the infiltration of various inflammatory cells in the airways, resulting in the narrowing of the bronchial lumen and the production of a large amount of mucus. When patients with bronchial asthma experience chest tightness, we can treat them with some nebulized inhalation medications. These medications are usually short-acting bronchodilators that can take effect within 3-5 minutes, quickly alleviating the symptoms of chest tightness. Additionally, patients should avoid exposure to allergens that may trigger asthma attacks, such as animal fur, viruses, and dust, to prevent recurrence of the symptoms.
