Donetsk - 2006. 1. Actuality and Scientific noveltyPresently a question in research and study of organs of breathing becomes more actual. Especially researchers were interested by the external breathing. Now development of science and medical diagnostics, researches the respiratory functions of patient on the basis of pneumogram, which we got by the special device «Spirograf». The given device allows to take off the basic parameters of breathing only. However in medicine another vehicle is used for research of the external breathing – it is «Poligraf». This vehicle is multifunction and takes off not only respirator data but also on the whole allows to estimate the functional condition of patient. Other name of the given vehicle – «Lie-detector». On the whole to estimate condition of patient of master's work I will not be, but is my task to analyse breathing functions and maximally estimate the respiratory system of man. For this purpose I develop a specialized computer system(SCS). 2. Aims and tasks of master's workAims: research of the respiratory functions of patient on the basis of pneumogram, which we got by the vehicle «Poligraf», and also the development of SCS for conducting and analysis of researches, and also conclusion of results.

3. The main points of master's work1. Researching respiratory system. Basic indexes characterizing the condition of respiratory system of a patient
All indexes characterizing being of function of the external breathing can be divided into four groups. Indexes characterizing pulmonary volumes and capacities behave to the first group. To the pulmonary volumes behave: respiratory volume, reserve volume of inhalation, reserve volume of inhalation, reserve volume of exhalation and remaining volume (amount of air, remaining in lights after maximal deep exhalation). To the capacities of lights behave: general capacity (amount of air being in lights after maximal inhalation), capacity of inhalation (amount of air, proper to the respiratory volume and reserve volume of inhalation), vital capacity of lights (consisting of respiratory volume, reserve volume of inhalation and exhalation), functional remaining capacity (amount of air, remaining in lights after quiet exhalation, - remaining air and reserve volume of exhalation).
2. Review of existent researches and developments. Common spirograf researchCommon spirograficheskoe research enables to define a basic exchange on the amount of the taken oxygen in, depth and breathing frequency, minute volume of breathing, maximal ventilation of lights, factious vital capacity of lights (the Tiffno and Votchala test), coefficient of the use of oxygen, respiratory equivalent Antoni:

Medical vehicle complex «Poligraf»In master's work is developed the specialized computer system for researching respiratory system on the basis of pneumogram. For this purpose it is necessary to develop software allowing to analyse a digital signal, urgent pneumogram, which we got by the medical vehicle complex «Poligraf».«Poligraf» – multifunction device. It has the enormous number of functional features by which it is possible to explore most exactly the condition of a patient and give preliminary assessment. It was supplied in research centers only. On the functional filling this device original «lie-detector». The device has the number of advantages, namely: ATSP – 32-channel, that allows to pass simultaneously the great number of data from different pays, and also a vehicle is in a position to change the special pays intended for diagnostics of the patient. The chart of transmission from the impulses of tension of thorax to treatment of data file and presentation of them as pneumogram is represented on the picture 2.
