Pulmonary alveoli are clinically known as pulmonary pustules, and patients should not smoke, otherwise the condition may be aggravated. Lung blisters refers to the alveolar cavity due to elevated pressure, alveolar rupture fusion, formed in the lung tissue diameter greater than 1cm air-containing cystic cavities, the cause of the disease is mostly seen in congenital bronchial developmental anomalies, chronic bronchitis, tuberculosis, etc., if a small number of small blisters generally have no obvious symptoms, if the blisters are more and the volume of the lungs may affect the lung function, appearing in the chest tightness, tightness of the air, and other symptoms. Smoking will ingest nitric oxide, tar, nicotine and many other harmful substances, causing damage to the airways and predisposing to pneumonia, chronic obstructive pulmonary disease, asthma, lung cancer and so on. Smoking in patients with pulmonary pustules will further deteriorate lung function and may also lead to rupture of pulmonary pustules and pneumothorax, which is life-threatening in severe cases. Patients with pulmonary pustules are advised to quit smoking and drinking, exercise appropriately, avoid dusty and hazy environments, and regularly assess their lung function.
