Pulmonary blisters are relatively common and are seen clinically in patients with chronic obstructive pulmonary disease, which can be treated with bronchodilator inhalation medication if there is clearly chronic obstructive pulmonary disease. If multiple pulmonary blisters are present at the tips of both lungs, do not be overly concerned. If the pulmonary blisters are small in size and there are no obvious clinical symptoms, no special treatment is usually needed, as long as the lung CT is reviewed regularly. If the pulmonary blister is large and the patient has obvious clinical symptoms, such as chest tightness, shortness of breath, shortness of breath, dyspnea, etc., and the patient’s lung function has been significantly damaged, surgical removal is recommended. Patients with pulmonary blisters should try not to do sudden strenuous exercise to avoid secondary pneumothorax caused by rupture of the blisters.
