Pulmonary blisters do not necessarily rupture. Asymptomatic, small-sized pulmonary blisters can be temporarily observed without special treatment; pulmonary blisters with primary disease or large size may rupture and increase in size or pneumothorax during strenuous exercise or forceful coughing, and require active treatment. A pulmonary blister is a large air sac formed by the rupture of the alveolar wall and fusion with each other due to the elevated pressure in the alveoli. It is usually secondary to tuberculosis, emphysema and other diseases, patients should be treated for the original disease, such as the use of antibiotics to control infection, in order to avoid the continued expansion of the pneumoconiosis; if the cause of the pneumoconiosis is unclear, avoid strenuous exercise or forceful coughing, so as not to stimulate the rupture of the pneumoconiosis; if the pneumoconiosis is caused by long-term smoking, in a smoky environment, often with coughing, asthma and other symptoms, such patients need to Leave the polluted environment or quit smoking. If the pulmonary blister is too large and affects the lung function, and symptoms such as difficulty in breathing and chest tightness occur, it can be surgically removed. Patients with pulmonary blisters must quit smoking to avoid irritating the respiratory tract and wear a mask when going out to avoid infections such as viruses or bacteria.
