肺弥散功能测定在支气管哮喘和慢性阻塞性肺疾病中的临床应用

Clinical Application of Pulmonary Diffusion Function in Bronchial Asthma And Chronic Obstructive Pulmonary Disease

目的探讨肺弥散功能测定在支气管哮喘和慢性阻塞性肺疾病鉴别诊断中的应用效果。方法选取BA以及COPD患者各70例,对其行肺通气功能及弥散功能检查,并进行比较。结果 BA组的VC、FVC、FEV1以及FEV1/FVC等均高于COPD组,差异均具有统计学意义(P<0.05)。BA组TLco/VA及TLco均高于COPD组,差异有统计学意义(P<0.05)。结论肺弥散功能测定在鉴别诊断BA及COPD中具有重要的临床价值。

Objective To investigate the effect of pulmonary diffusion function in the differential diagnosis of bronchial asthma and chronic obstructive pulmonary disease. Methods The pulmonary ventilation function and diffusion function were examined in 70 patients with BA and COPD,and the comparison was made between them. Results BA group of VC,FVC,FEV1 and FEV1/FVC were significantly higher than the COPD group,the difference was statistically significant（P〈0.05）. BA group of TLco/VA and TLco were significantly higher than the COPD group,the difference was statistically significant（P〈0.05）. Conclusion Pulmonary diffusion function has important clinical value in the differential diagnosis of BA and COPD.
