The symptoms of patients with pulmonary blisters are related to the size and number of blisters and the underlying disease. Patients with small pulmonary blisters and no underlying disease may have no symptoms and may be detected only incidentally during a physical examination with a chest X-ray or CT of the lungs. There are no positive signs on physical examination. Pulmonary blisters in this case do not require special treatment. If the pulmonary blisters are large and numerous, the patient may experience shortness of breath and chest tightness. In particular, in patients with emphysema, the shortness of breath and chest tightness will be more obvious if the area of pulmonary blisters exceeds 1/2 of one side of the chest cavity, sometimes accompanied by chest pain. In case of combined lung diseases, the symptoms will also be more severe than those of simple pulmonary blisters. Rupture of the pulmonary blister to form a pneumothorax can cause fatal respiratory distress, which may be life-threatening if left untreated. On examination there is the presence of bulging sounds and no normal breath sounds can be heard on auscultation. The above can be found that simple pulmonary alveoloplasmosis is not very serious, the key is to control it so that it stops not to continue to develop, pulmonary alveoloplasmosis is irreversible and will only progressively aggravate. Once the alveolar pneumonia is found to increase in size and the symptoms of shortness of breath, it is recommended that surgery be performed as soon as possible to avoid further aggravation, which can lead to pneumothorax.
