Микроэмболия возникает из-за попадания микропузырьков (МП) кислорода или воздуха в артериальную систему пациентов. Существующие системы АИК имеют встроенные системы регистрации МП, но не включают системы удаления МП в контуре. Аппараты ЭКМО имеют артериальные фильтры, но не могут обеспечить надежную фильтрацию МП размером меньше 40 мкм в широком диапазоне расхода. Нами предложен альтернативный метод, который предполагает применение эффективного устройства динамической фильтрации (УДФ) как больших, так и малых пузырьков. Проектирование включает разработку двух вариантов УДФ для условий гемодинамики как взрослого, так и педиатрического пациентов. Устройство устанавливается в выходной магистрали АИК и ЭКМО и обеспечивает достаточную сепарацию пузырьков из магистралей в диапазоне кровотока 3,0–5,0 л/мин для взрослого пациента и 0,5–2,0 л/мин для педиатрического пациента. Разработанные компьютерные модели показали возможность сепарации МП размером менее 10 мкм. Применение данного устройства позволит уменьшить вероятность воздушной эмболии в несколько раз и позволит пересмотреть концепцию применения дорогостоящих артериальных фильтров.</p></abstract><trans-abstract xml:lang="en"><p>The use of extracorporeal circulation systems (cardiopulmonary bypass pumps, ECMO) can lead to brain and coronary artery microembolism, which significantly reduces postoperative rehabilitation and often leads to severe complications. Microembolism occurs when oxygen or air microbubbles (MBs) enter the arterial system of patients. Existing CPB pumps come with built-in bubble trap systems but cannot remove bubbles in the circuit. ECMO devices have arterial filters but cannot reliably filter out &lt;40 μm bubbles in a wide flow range. We have proposed an alternative method that involves the use of an efficient dynamic bubble trap (DBT) for both large and small bubbles. The design includes development of two DBT variants for hemodynamic conditions of adult and pediatric patients. The device is installed in the CPB pump and ECMO outlet lines. It provides sufficient bubble separation from the lines in a blood flow of 3.0–5.0 L/min for adults and 0.5–2.0 L/min for children. The developed computer models have shown that MBs smaller than 10 μm can be filtered. The use of this device will greatly reduce the likelihood of air embolism and provide the opportunity to reconsider the concept of expensive arterial filters.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сердечно-легочный обход</kwd><kwd>микропузырьки</kwd><kwd>ЭКМО</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cardiopulmonary bypass</kwd><kwd>microbubbles</kwd><kwd>ECMO</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">Cavayas YA, del Sorbo L, Fan E.
