Administering appropriate oxygen therapy can have certain benefits for patients with bronchial asthma.

The onset of bronchial asthma is mainly due to the edema of the bronchial mucosa and the constriction of the smooth muscles outside the bronchi leading to the narrowing of the lumen. This makes it difficult for gases to pass normally through the airway into the alveoli. Patients may experience symptoms such as coughing, chest congestion, breathlessness, or wheezing, which are primarily due to the pathophysiology of bronchial asthma.

Of course, providing patients with appropriate oxygen therapy during an asthma attack can be beneficial, temporarily solving the problem of hypoxia. However, it is important to understand that asthma patients are not primarily suffering from a lack of oxygen but from ventilation dysfunction, which leads to the inability to expel carbon dioxide, the waste gas, from the body. Therefore, the fundamental treatment should focus on improving airway spasms and narrowing to enhance ventilation.
