The lungs need to be partially removed for various reasons, which will affect the normal lung function, which is significantly reduced compared to the lung function before the removal. This may be manifested by symptoms of varying degrees, such as wheezing, shortness of breath, chest tightness, shortness of breath, and other manifestations of dyspnea. Some patients may also have compensated atelectasis and emphysema due to the dramatic decline in lung function, which may result in a markedly progressive worsening of expiratory dyspnea. Ventilation and ventilation of the lungs will be restricted, which may cause carbon dioxide retention and hypoxia, leading to hypoxemia and hypercapnia, causing respiratory distress and respiratory failure.
