Patients with single and smaller alveoli may be asymptomatic. Voluminous or multiple pulmonary alveoli may have symptoms such as chest tightness, shortness of breath, and dyspnea.
Pulmonary alveoli are the result of elevated intra-alveolar pressure, rupture of the alveolar walls to fuse with each other, and finally the formation of huge vesicular changes. The cause of the disease is long-term inflammation of the small bronchial tubes, mucosal edema, lumen narrowing, secretion retention or the production of living valve effect, so that the inhalation of gas in the alveoli is not easy to exhale, the alveolar pressure rises, alveolar septal destruction fused with each other, and ultimately the formation of large pulmonary alveoli.
Clinically, patients with single and small pulmonary alveoli may be asymptomatic. Large or multiple alveoli may have symptoms such as chest tightness, shortness of breath and dyspnea.
When sudden onset of shortness of breath, cough, dyspnea, cyanosis, displacement of the trachea and mediastinum to the opposite side, tympanic sounds on percussion of the affected side, and disappearance of respiratory sounds on auscultation, spontaneous pneumothorax should be suspected to occur, and there may be chest pain similar to angina pectoris.
Pulmonary alveolus can sometimes be secondary infection, patients often have cough, cough sputum, chills and fever.
If the above symptoms occur, it is recommended to go to the hospital in time for early and regular treatment.
