Patients with pulmonary alveoli can breathe moderately deeply, but they should be careful to closely observe changes in the alveoli and avoid strenuous exercise to prevent alveolar rupture. Pulmonary alveoli are formed when the pressure inside the alveoli increases due to various reasons, the alveolar walls rupture and the alveoli fuse with each other. Moderate deep breathing has little effect on the patient, but if the patient’s alveoli are relatively large, deep breathing of a greater magnitude may easily lead to alveolar rupture and pneumothorax, which requires close observation and avoidance of strenuous exercise. If the alveoli continue to increase in size and cause chest pain, wheezing and other symptoms, it is necessary to consult a doctor in time for observation and receive standardized treatment under the guidance of the clinician after clarifying the condition, so as to avoid delaying the condition.
