Pulmonary alveoli are generally not life-threatening. For patients with small pulmonary alveoli, there are no obvious symptoms and no special treatment, patients are advised to quit smoking, pulmonary ventilation function can be checked to assess lung function, and bronchodilators can be used if there is obstructive ventilation dysfunction. For patients with huge pulmonary alveoli, they may experience chest tightness and shortness of breath after activity, but it should be noted that such alveoli may rupture to form pneumothorax when the patient coughs hard or carries heavy objects, and then the disease becomes serious. If the pneumothorax volume gradually increases without timely treatment, it may endanger the patient’s life, especially for patients with tension pneumothorax, which is mostly accompanied by the presence of decreased blood pressure and respiratory failure. If the patient also has chronic obstructive pulmonary disease or bronchial asthma, and some chronic heart diseases, the patient’s condition becomes more critical, and the patient’s life may be at risk if not treated effectively in time. Therefore, for patients with pulmonary alveoli, especially those with giant alveoli, appropriate measures should be taken to avoid the rupture of the alveoli and the formation of pneumothorax to avoid the deterioration of the disease.
