Pulmonary herpes is clinically known as pulmonary blisters and is mainly seen in chronic obstructive pulmonary emphysema and pulmonary heart disease. The emphysema ruptures following the development of emphysema in the lung and fuses into a new large air-containing cavity. There is no clinically significant pneumothorax without affecting normal respiratory function and no special treatment is required. If the pneumothorax is relatively large and numerous and seriously affects the respiratory function, with varying degrees of impaired expiration and ventilation, wheezing, shortness of breath, chest tightness, shortness of breath or even respiratory failure, symptomatic and etiologic treatment is required, such as oxygenation and symptomatic treatment to stop coughing and calm asthma. If necessary, surgery to remove and repair the lung tissue is required to relieve the symptoms.
