Pulmonary maculopathy is a chronic disease of the respiratory system that refers to the formation of air-containing cavities larger than 1 cm in diameter within the lung tissue. Whether a pulmonary blister is serious or not often needs to be determined on a case-by-case basis and cannot be generalized. Patients can choose the appropriate treatment, such as conservative treatment or surgery, based on specific symptoms and examination results and after detailed consultation with the doctor to avoid serious conditions that are difficult to handle or life-threatening. If the pulmonary blister is solitary, or if the size of the blister is small and there is no pressure on the surrounding lung tissues, the condition is usually not too serious and usually does not require special treatment and can be observed first by adjusting living habits; if the pulmonary blister occurs on the surface of the dirty pleura or is too large, it can lead to pneumothorax, pulmonary insufficiency and other problems, or the pressure on the lung tissues can cause severe hypoxia, which can affect the patient’s life. The situation is more serious and often requires surgical treatment as prescribed by the doctor. In daily life, especially in patients with severe symptoms, it is necessary to pay attention to rest and avoid breath-holding and coughing to avoid rupture of the pulmonary blisters. At the same time, you can eat some fresh vegetables and fruits, such as celery and oranges, to promote recovery.
