Models and tools for designing of Medical Informational-Analytical System (MIAS)
of Object Shelter Rehabilitation Center

Abstract

Efficient operation of complex automated diagnostic equipment of Object Shelter (SO) Rehabilitation Center requires establishment of Medical Informational-Analytical System (MIAS), which will allow (based on monitoring data processing) solution of issues related to informational support of professional personnel selection in view of OS work execution, control of personnel health, support of professional suitability, etc.
Up-to-date practical method of forming the ensemble of models for MIAS system designing is to be suggested. The method is based on the concept of high-level architectural design of automated (informational) systems. The ensemble of models is established on the basis of main set, which corresponds to procedure-oriented, object-oriented, and information-oriented methods of system designing. Each method supplements and supports the others; therefore the ensemble ensures the most complete representation of hyperspace, repertoire, and procedures of designing.
To create the model of any applied graphic notation, software of Computer Associates International Inc. company will be used, which ensures equation of all design procedures and integration of knowledge about future system all over the technological chain of designing.
Use of the method during development, support, and progress of OS Rehabilitation Center MIAS is assumed during international SIP program realization at Chernobyl NPP.

Key words: ensemble of models, method of MIAS designing.

The decision rule for the estimation of the vegetative paroxysm by skin somatic response data

Abstract

Skin somatic evoked potential were examined in 33 patients with vegetative paroxysm and in 32 health subjects. For spreading practical usage of skin somatic response method in vegetative disturbance diagnosis were developed the decision rules on the base which one it’s possible to determine the group persons who has the risk of vegetative paroxysm. The usage of this decision rule to examine group was demonstrated that correct refer to health subject or to patients with vegetative paroxysm was 88%. Our data allowed to recommend the investigation of vegetative EP in patients with vegetative disorders.

Key words: vegetative paroxysm, risk appearance, SSEP, decision rule.

Clinical analysis of heart rate variability and its apparatus-program equipment

Abstract

Purpose of studies during 20 years in Chelyabinsk medical academy were researches and development of rhythmocardiography (RCG) method for heart rate variability (HRV) clinical analysis, adapted to condition of the practical cardiology, hardware apparatus-program complex (APK) for it and approbation both in non-nosological cardiodiagnosis. RCG was working out on the background of da database in 42300 disease cases and 14s-year’s experience of the RCG using in practical medicine. Also APK CAP-RC-01-«Micor» was created and produced, as well as HRV analysis with evaluation wave structure of the temporary interval between heart systoles in patients with different forms of cardiovascular pathology. The main requirements were substantiated to hardware-program complex for HRV analysis. It was proved the broad possibilities of high-resolution HRV analysis for evaluation of the peripheral regulation of the pacemaker sinus node activity, which has different variants, depended on the disease pathogenesis.

Monitoring of heart rate variability as reference method of an estimation of a functional state of an organism during hyperbaric oxygenation

Abstract

The exploratory retrospective basic clinical research of the current practice which is based on the analysis of 607 clinical supervision during carrying out of 3892 sessions of hyperbaric oxygenation (HBO) at exogenous intoxications and diseases with obligate infringements of vegetative regulation. Comparison of dynamics
of thirty known parameters of heart rate variability (HRV) during HBO and reference clinical attributes of current of diseases is executed.
Dynamics of parameters HRV during HBO at various diseases depend on a sex (p <0,001), age (p <0,001), gravity of the general state (p <0,001) and diseases
(p <0,001). A lot of informative and statistically significant mathematical models and the data which show is submitted, that dynamic lines of parameters HRV are adequate criteria of functional state of an organism (FSO), allow to predict an outcome of diseases and efficiency
of treatment.
As a result of research the standardized protocol of monitoring FSO is developed during sessions of HBO according to parameters HRV and principles
of selection of optimum dozes of HBO are determined.

Key words: heart rate variability, a hyperbaric oxygenation, a functional state of an organism.

Adaptive and pathological changes of the fetal-placental complex during intrauterine hypoxia after pregnancy complicated by obstetric and somatic deseases

Abstract

Intrauterine hypoxia leads to violation of fetal development and pathological adaptation after birth. The purpose
of present study was to evaluate status of newborns cardiovascular system and peculiarities in their postnatal adaptation after acute and chronic fetal hypoxia. We observed on 140 children (age 1 day-3 month) from mothers with normal and complicated pregnancy. Investigation included clinical, laboratories, electrocardiografic methods and also computer analysis of cardiac rhythm (CARS) and morphologic study of placenta. We determined that light acute hypoxia caused mainly functional changes in placenta and fetal organism. This newborns had high level of simpatico-adrenal activity, which normalized during several weeks. Chronic hypoxia on early studies caused structural changes in terminal villi of placenta – rise capillaries amount and area, rise amount and extent of syncitio-endothelial membranes which provided satisfactory fetal development. Severe chronic hypoxia leads to serious structural violations in placenta – dystrophy and destruction of syncitial epithelium, breach of microcirculation in terminal villi, and main fetal systems. Newborns after severe chronic intrauterine hypoxia had exhaustion of simpatico-adrenal system. This pathological reaction can be considered as a foundation for different desiases wich taked place occur in this group of children.

Keywords: placenta, fetus, newborn, adaptation, hypoxia, growth retardation, computer analysis of cardiac rhythm, electrocardiography.

Abstract

The system of computer simulation of the vital processes of organs and systems of human body was elaborated. In the process of its designing the modern systematic approach was used, based on mathematic simulation of the processes of human physiological activity, taking into account all intercommunications between different organs, biochemical and enzymatic transmutations in organs and tissues, influence of environment. User can model any state of human body by setting different meanings to the appropriate indicators in any subsystem will lead to automatic revise of all parameters of the system, which were connected with modeling condition. By its functional capabilities the system doesn’t have analogs in medical simulators and can be widely used in tuition process at higher medical institutions, scientific medico-biological investigations, clinical practice.
