Pulmonary alveoli are air-containing saccular cavities formed when the walls of the alveoli rupture and fuse with each other due to various reasons.
Lung blisters are caused by various reasons that lead to increased pressure in the alveolar cavity, the alveolar walls rupture, fuse with each other, and finally form an air-containing cystic cavity in the lung tissue. Causes of pulmonary maculopapularity include long-term recurrent pneumonia, tuberculosis, chronic obstructive pulmonary disease, and other diseases. There are also some congenital bronchial dysplasia, which can lead to congenital pulmonary herpes.
The formation of pulmonary pustules is a chronic process. Learning to swim does not usually lead to rupture of the alveolar walls and associated fusion, which does not lead to the formation of pulmonary pustules. However, patients with pulmonary pustules may experience increased alveolar pressure when swimming, especially snorkeling, leading to rupture of the pulmonary pustules and formation of a pneumothorax.
Learning to swim does not lead to the development of pulmonary pustules, but snorkeling is not recommended for patients with pulmonary pustules, and prompt medical attention is recommended for any discomfort.
