Description: Abstract. In this paper examines functional relationship between diastolic and systolic blood pressure. The use of methods of cluster analysis and regression analysis allowed to receive a family of regression models that used as nomograms. Proximity analysis of arterial pressure to regression equations, as well as their dynamics with respect to the curves with multiple measurement allowed us not only to diagnose pathologies of the circulatory system, but also to evaluate the effectiveness of treatment interventions.
Keywords: circulatory system, blood pressure, pathological condition, the diagnostic system
