Pulmonary blister rupture is roughly divided into two cases: 1. Pulmonary blister rupture under the pleura can lead to spontaneous pneumothorax, patients mostly have symptoms such as coughing, wheezing, shortness of breath, dyspnea, inability to lie down, etc., which can be clearly detected on imaging, and different measures are taken according to their pneumothorax volume. For patients with small pneumothorax volume and no other underlying diseases, patients are advised to rest more and avoid activities that increase chest pressure to avoid aggravation of pneumothorax, which can be gradually absorbed. For patients with large pneumothorax or serious underlying lung diseases, thoracentesis is required to extract the pneumothorax or set closed drainage tube to drain the pneumothorax, which can be gradually absorbed with the remission of the disease. 2. Its impact on lung function is small and is not subject to special treatment.
