本文对５２３例６０岁以上老年人进行了肺功能测定，其中健康组１０９例，健康吸烟组１０９例，慢性支气管炎组６７例，肺气肿组１９６例，肺心病组４１例。结果显示，健康老年人的肺功能随年龄增加而减低，长期吸烟不仅损害肺通气功能，亦损害小气道功能。而慢支和肺气肿患者随肺气肿程度的加重肺功能损害愈明显。故对ＣＯＰＤ患者应定期测定肺功能，了解肺功能损害程度，采取措施，积极预防。 In this article, 523 patients over the age of 60 were tested for lung function, including 109 in the healthy group, 109 in the healthy smoking group, 67 in the chronic bronchitis group, 196 in the emphysema group, and 41 in the pulmonary heart disease group. The results showed that the lung function of healthy elderly people decreased with age. Long-term smoking not only impaired lung ventilation function, but also impaired small airway function. In patients with chronic bronchitis and emphysema, the severity of emphysema increases lung function damage. Therefore, patients with COPD should be tested regularly for lung function, to understand the degree of lung damage, and to take measures to prevent it.
