Материалы и методы. В исследовании приняли участие 44 пациента с нативной радиоцефальной фистулой, сформированной в дистальной трети предплечья. Всем пациентам проводили запись шума артериовенозной фистулы с использованием электронного стетоскопа. Сформированная база из 653 спектрограмм подверглась анализу по методу оценки величин энтропии и сложности. Для выявления закономерностей был применен алгоритм кластеризации Уишарта. Результаты. Разработанный алгоритм анализа аудиограмм, основанный на определении «хаотичности» и «сложности» звука, позволяет разделить шумыартериовенозной фистулы на три кластера, каждому из которых соответствует своя вероятность дисфункции. Данный алгоритм может использоваться при разработке индивидуальных мобильных устройств для постоянного мониторирования состояния артериовенозной фистулы.</p></abstract><trans-abstract xml:lang="en"><p>The study aims to develop an algorithm for assessing spectrographic features of arteriovenous fistula dysfunction for hemodialysis. Materials and methods. Forty-four patients with native radiocephalic fistula formed in the distal third of the forearm participated in the research. Using electronic stethoscope, the noise of arteriovenous fistula was recorded in all patients. 653 spectrograms were analyzed with the method of evaluating entropy and complexity value. The algorithm of Wishart clustering was applied to detect consistency. Results. The algorithm developed for audiograms analysis and based on evaluation of “chaotic” and “complex” sound makes it possible to divide arteriovenous fistula noise into three clusters. Each cluster complies with its possibility of dysfunction. The algorithm may be applied in developing individual mobile devices to monitor constantly the condition of arteriovenous fistula.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кластеризация шумов</kwd><kwd>почечная недостаточность</kwd><kwd>сосудистый доступ</kwd><kwd>гемодиализ</kwd><kwd>стеноз</kwd><kwd>тромбоз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>noise clustering</kwd><kwd>kidney failure</kwd><kwd>vascular access</kwd><kwd>hemodialysis</kwd><kwd>stenosis</kwd><kwd>thrombosis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Okpechi I.
