Документ Metrological support of pulse oximeters(Національний технічний університет "Харківський політехнічний інститут", 2022) Tverytnykova, Elena; Drozdova, Tatyana; Demidova, Yu. Ye.; Kuzmenko, NataliiaThe experience of the International Medical Device Regulators Forum in the use of products for oxygen therapy based on the study of guidelines, international and European regulations on medical devices is considered. Emphasis is placed on issues related to the metrological support of pulse oximeters. The global situation with the pandemic increases the relevance of selected topics. Continuous monitoring of blood oxygen saturation is one of the most important elements in the diagnosis and treatment of COVID-19. Despite the fact that the use of pulse oximeters does not require special medical knowledge, calibration and special maintenance, it is still necessary to control their reliability and accuracy of measurement. The study of pulse oximeter MD300M in accordance with the requirements of DSTU 8893:2019 "Metrology. Pulse oximeters. Calibration Method" 2020. Analysis of MD300M pulse oximeter calibration results revealed that this pulse oximeter was calibrated by the saturation and pulse measurement channel, as the maximum deviation of the measured saturation value from the pulse oximeter calibration measure does not exceed the pulse oximeter measurement documentation specified in the operating documentation. The discreteness of the MD300M pulse oximeter and the discreteness of the reference device MPPO-2, which are specified in the passports for the respective devices, have the greatest influence on the measurement uncertainty.Документ Environmental management as a component of an integrated management system for gas condensate and oil processing enterprises(Національний технічний університет "Харківський політехнічний інститут", 2020) Tverytnykova, Elena; Drozdova, Tatyana; Demidova, Yu. Ye.The results of activity and stages of implementation of various measures of environmental policy of the enterprise are considered on the example of Shebelinsky department of gas condensate and oil processing. The structural scheme of the ecological management system model as an important component of the integrated management system of the gas condensate and oil refining enterprise is proposed on the basis of scientific literature, regulatory and legal documents using structural-logical method, systematization and generalization, and methods of meaningful and comparative analysis. This work also describes the specifics of ecological standards implementation based on ISO 9000 and ISO 14000 series for integrated management system development. It has been proved in practice that development and implementation of the integrated management system in the natural gas liquids and oil processing enterprise provides certain advantages, specifically, improves the overall products competitiveness, helps to adapt faster to the market environment, shapes environmental policy and approaches for effective resource management. The integrated management system development process consists of 4 basic stages, namely, planning, implementation, verification, and adjustment. Complex process and system approach represents an integral part of the integrated management system development. While being gradually implemented, the application of the additive and simultaneous integration models made it possible to create a single management system based on the requirements of different standards and significantly reduce the documentation volume.
