The subjects were divided into four groups, three of which consisted of patients with various degrees of lung obstruction, while the fourth was the control group. The patients were divided according to the spirometric values: VC, FEV1, FEV1/VC%. The diffusing capacity was determined on the basis of the single breath method and graphical separation of the diffusion components was performed. It was found that the diffusing lung capacity was slightly lower in patients with mild to severe obstructive lung disease. The capillary blood volume was also slightly lower. Correlations between the degree of obstruction of the respiratory system and the diffusing lung capacity or the lung capillary blood volume was not statistically significant (p greater than 0.5). In studying patients with obstructive lung disease we were unable to establish which of the diffusion components significantly affected the value of the total diffusing lung capacity.
受试者被分为四组，其中三组由不同程度的肺阻塞患者组成，而第四组为对照组。患者根据肺活量测定值进行分组：肺活量（VC）、第一秒用力呼气容积（FEV1）、FEV1/VC%。基于单次呼吸法测定弥散能力，并对弥散成分进行图形分离。结果发现，轻度至重度阻塞性肺疾病患者的肺弥散能力略低。肺毛细血管血容量也略低。呼吸系统阻塞程度与肺弥散能力或肺毛细血管血容量之间的相关性无统计学意义（p大于0.5）。在研究阻塞性肺疾病患者时，我们无法确定哪些弥散成分对总肺弥散能力值有显著影响。
