Whether or not a ruptured alveolus repairs itself depends mainly on the size of the ruptured alveolus and the condition of the lungs themselves. If the ruptured alveoli are small and few in number, the patient’s lungs are functioning well and will be able to absorb the ruptured alveoli and repair them normally. However, if the alveolar rupture is extensive and the alveolar rupture is large, it is easy to cause complications, such as chronic obstructive pulmonary emphysema, pulmonary atelectasis, and the emergence of new alveoli, or even combined with more serious infections to cause lung abscesses. At this time, the lung function is low and it is difficult to repair itself, so it is necessary to carry out the necessary medical interventions, such as anti-infective treatment, and give the necessary oxygen intake. It is also necessary to do some breathing exercises, such as balloon blowing training, to prevent the decline of lung function and promote the repair of alveoli.
