There are no contraindications when the alveoli are small, but when they are large, it is necessary to avoid strenuous exercise and over-expressive treatment, which may cause the alveoli to rupture and form a pneumothorax. Pulmonary alveoli are a relatively common clinical condition, and are usually visualized as air-containing cystic cavities. When the cystic cavity is small, no human intervention is needed, but when the cystic cavity progresses to a large size, rupture must be prevented, especially before ventilator or hyperbaric oxygen chamber treatment must be carefully selected. In the aspect of life, attention should also be paid to ensure a light diet to keep the bowel clear to prevent rupture of the vesicle due to deep breathing and straining during defecation, and try to help the patient to correct the bad habits of life, quit smoking, abstaining from alcohol, and pay attention to rest.
