Pulmonary pustules are irreversible organic lesions that can only be treated with some therapeutic measures to avoid further progression or complications, but cannot be eliminated or self-healed. Pulmonary blisters are air-containing saccular cavities formed by the fusion of alveolar septa ruptured by various causes, and when the saccular cavities are larger than 1 cm, they are called pulmonary blisters. After the formation of pulmonary blisters, the pressure inside the blisters rises, which can cause further expansion of the cystic cavity, and in severe cases, can seriously affect lung function or cause pneumothorax. After the destruction of lung tissue, there is no regeneration function, so the formation process of pulmonary blisters is irreversible, once formed after the normal structure can not be restored, not to mention the possibility of self-healing, can only be prevented through some measures to prevent its further increase, such as smoking cessation, avoiding infections, and actively treating the primary disease of chronic obstructive pulmonary disease, and so on. Surgery can be considered for larger lung blisters that are combined with infection or bleeding and cause pneumothorax, and thoracoscopic resection of part of the lung tissue is often used. Lobectomy can also be performed if the lung lobe is severely damaged. When pulmonary blisters occur, it is necessary to actively consult the doctor and follow the doctor’s instructions for reasonable treatment.
