Для эксперимента был разработан и собран гидравлический стенд, способный развить противодавление на выходе насоса до 200 мм рт. ст. Измерения проводились для осевого насоса крови «Стрим Кардио» (Россия). Проведены серии экспериментов для различных скоростей вращения в интервале от 7500 до 10 000 об/мин. При этом начальное избыточное давление составляло 85, 100 и 120 мм рт. ст.</p></sec><sec><title>Результаты</title><p>Результаты. Полученные данные в ходе проведенных испытаний на гидравлическом стенде позволяют получить суммарную расходно-напорную характеристику с учетом зоны обратного потока, которая находится в отрицательном диапазоне расхода осевого насоса. При потоке через насос, равном 0 л/мин, перепад давления на насосе составляет 85 мм рт. ст., для перепада давления в 100 мм рт. ст. расход составляет –2,5 л/мин, а для давления в 120 мм рт. ст. –5 л/мин. Полученные расходно-напорные характеристики для зоны отрицательных значений расхода являются непрерывным продолжением характеристик насоса, сохраняя угол наклона и характер, близкий к линейному.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to study the hydraulic characteristics of an axial pump under conditions where the external back pressure at the outlet exceeds the maximum pressure generated by the pump, and to determine the corresponding headcapacity curves (HCC) in this operating mode.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A hydraulic test bench was designed and assembled for the experiments, capable of generating outlet back pressure up to 200 mmHg. Measurements were performed using axial blood pump Stream Cardio (Russia). A series of tests was conducted at rotational speeds ranging from 7,500 to 10,000 rpm. Initial excess pressures of 85, 100, and 120 mmHg were applied.</p></sec><sec><title>Results</title><p>Results. The experimental data obtained on the hydraulic test bench made it possible to determine the complete HCC of the axial pump, including the reverse-flow region corresponding to negative flow rates. At a flow rate of 0 L/min, the pressure drop across the pump was 85 mmHg. At a pressure drop of 100 mmHg, the flow rate reached –2.5 L/min,</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>сердечная недостаточность</kwd><kwd>система вспомогательного кровообращения</kwd><kwd>расход насоса</kwd><kwd>напор насоса</kwd><kwd>осевой насос</kwd><kwd>обратный поток</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heart failure</kwd><kwd>mechanical circulatory support</kwd><kwd>pump flow rate</kwd><kwd>pump pressure</kwd><kwd>axial pump</kwd><kwd>reverse flow</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">Slaughter MS, Pagani FD, Rogers JG, Miller LW, Sun B, Russell SD et al.
