Abstract:
Standard strategies of evaluation of functional cardiovascular system condition (СSС) take an intercoupling of into account systolic and diastolicheskoe arterial pressures and do not take a dynamic feature into account, what is a warmhearted reduction frequency. Offered universal method of evaluation of physiological condition ССС to the account of entering a dynamic feature, allows defining average dynamic pressure, accounting for one reduction warmhearted muscles. Herewith exceedingly it is important to value a quality of getting results. This reasonable execute modern metrological analysis with attraction of. At present metrological analysis of medical measurements practically not designed. Possibility of realization of metrological analysis appears only after determinations of structure of object: physiological system, medical technology and so on. As an initial structure is offered physiological system category, connected with changing an arterial pressure, containing under category physiological transformations and under category instrumental transformations. This has brought about shaping an measurement category (MC). Details MC enable a physiological system structure on the grounds of structures Dyhin-Sudakov. Then appears an unrolled category of process of valuing a functional condition on the strategy of test laden organism. This category is used for the determination of the sources of inaccuracy, syntheses of governing a packed procedure of finding of value of average dynamic pressure and getting an expression of packed inaccuracy. This equation study enable to fix a technology of testing with provision for appearing inaccuracy of status measurements by correcting a technology. Together with that appearing inaccuracy of results of measurements brings about forming the areas нечувствительности on borders of intervals of treatment influences that particularly it is important at the purpose of much crossbar technologies of treatment influences
