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.

Determination of functional aerobic impairment, i.e.

At the submaximal level of 90 Watts the cardiorespiratory efficiency, as reflected by the values of double product (DP) and ventilatory equivalent (VE) was statistically different in the three Groups (A less than B less than C). At the maximal work the females, compared to sedentary males, achieved lower values (P less than 0.

Spiroergometric examinations under a load of 1 w/kg is a highly informative method of evaluating the physical performance capacity of children with rheumatic heart diseases. By using this method it is possible to obtain quantitative and qualitative functional characteristics of their cardiopulmonary system, to disclose latent cardiac insufficiency.

Standard and submaximal physical load tests were contrasted in studying the functional state of the cardio-respiratory system in healthy individuals and in patients with coronary atherosclerosis, post-infarction cardiosclerosis, mitral lesions and cardiac-pulmonary insufficiency. The application of physical load tests of different types is shown to be instrumental in obtaining a mutually complementary information about the function of the cardiac-respiratory system and the degree of pulmonary and cardiac decompensation. The authors attach great importance to determining the ratio of an actual oxygen uptake to its proper values and suggest using this indicator, called by them performance capacity index, in quantitative appraisal of physical capacity to perform work.
