Abstract
Objective To discuss signification of diffusion functiong of lung in patients with stable COPD. Methods 100 cases with stable COPD and 30 healthy volunteers were selected as study group and control group. FEV1, FEV1/FVC, DLCO, Dm, Vc were detected. Results DLCO, Dm, Vc of moderate group, severe group and very severe group decreased apparently compared with control group(P < 0.01). DLCO, Dm, Vc decreased with different stages of sever of illness. Correlation index of DLCO between Dm was 0.899, P < 0.01. Correlation index of DLCO between Vc was 0.874, P<0.01. Correlation index of Dm between Vc was 0.821, P<0.01. DLCO, Dm, Vc showed linear correlation with different stages of sever of illness(P < 0.01). Conclusion Diffusion functiong of lung in patients with stable COPD decreases apparently with different stages of severty of illness.关键词
