The analysis of rabbit's cardiovascular hemodynamic indices under experimental diphtheria intoxication had shown that the adaptation of the cardiovascular system to direct heart damage is visualized by the study of three-dimensional correlation between intraventricle BP indices of left and right ventricles, and systolic and diastolic BP indices. With the help of empiric production functions it was shown that the intraventricle BP's contribution of left and right ventricles into formation of systolic and diastolic BP in experiment were different from control group, but production functions of systolic and diastolic BP had produced the constant effect of production and therefore were Cobb-Douglas production functions.
