Twenty three male subjects 21 to 53 aged were undergone to lung diffusion test using breath holding method. Each subject was tested three times in different days. The results were evaluated by Bartlett's Chi-square test and by Kendall's coefficient of concordance. Correlation between the CO distribution and diffusion index (R&DCO), the Helium distribution index (RHe), the time of breath holding and the volume of "single breath" was found. It seems it will be possible to improve the inter-personal estimation to 1.25% about.
23名年龄在21至53岁之间的男性受试者采用屏气法进行了肺扩散试验。每位受试者在不同日期进行了三次测试。结果通过Bartlett卡方检验和Kendall协调系数进行评估。发现一氧化碳分布与扩散指数（R&DCO）、氦气分布指数（RHe）、屏气时间和“单次呼吸”量之间存在相关性。似乎有可能将人际估计提高约1.25%。
