摘要目的分析慢性支气管炎、阻塞性肺气肿患者其它肺功能因素对弥散功能的影响。方法回顾性分析120例慢支、肺气肿患者弥散功能正常组与异常组一氧化碳弥散(DLco)与第一秒用力呼气量(FEV1)、RV/TLC、PaO2的相关性。结果慢支、肺气肿患者DLco减低与FEV1呈高度直线正相关,与RV/TLC呈高度直线负相关,DLco异常组较DLco正常组PaO2减低。结论慢支、肺气肿患者弥散功能减低与肺气肿毛细血管床丧失有关,亦与肺泡体积增大,通气功能减低所致通气/血流异常有关。 Objective To investigate the effect of other lung function parameters on diffusing capacity in patients with chronic bronchitis and emphysema . Methods 120 patients with chronic bronchitis and emphysema were retrospectively studied. They were divided into two groups: normal DLco group and abnormal DLco group. The correlation of DLco with FEV1, RV/TLC and PaO2 was analyzed. Results In patients with chronic bronchitis and emphysema, DLco was reduced and positively correlated with FEV1, while it was negatively, correlated with RV/TLC, PaO2 was lower in abnormal DLco group than in normal DLco group. Conclusions The reduced diffusing capacity in patients with chronic bronchitis and emphysema is related to the loss of lung capillary bed, abnormal ventilation/blood flow due to enlarged alveolar space and reduced ventiation.
