The paper deals with the objectivisation of quantitative criteria for defining the functional classes of the oxygen transport system. For this, the spiroergometric findings of patients with valvular and congenital heart diseases before and after their surgical correction were processed by using currently available mathematical methods of cluster analysis. Five classes of the functional status were identified. These included 0, I, II, III, and IV. The criteria proposed can be useful in cardiac surgical care.
本文探讨了用于定义氧运输系统功能类别的定量标准的客观化问题。为此，运用现有的聚类分析数学方法，对瓣膜性和先天性心脏病患者手术矫正前后的运动心肺功能测试结果进行了处理。确定了五类功能状态，分别为0、I、II、III和IV。所提出的标准在心脏外科护理中可能会有用。
