During the development of this research area, the team secured approximately 40 patents for related inventions. Oxygen-producing antihypoxants include warm alkaline hydrogen peroxide solutions (WAHPSs), which, upon injection into sputum, mucus, pus, blood, or other tissues, rapidly convert them into a soft oxygen foam. This occurs because many bodily tissues contain the enzyme catalase, which, in an alkaline environment under hyperthermic conditions, accelerates the decomposition of hydrogen peroxide into water and molecular oxygen by millions of times. Catalase-mediated cleavage of the H<sub>2</sub>O<sub>2</sub> in 100 mL of a 3% hydrogen peroxide solution yields approximately 1.408 g of molecular oxygen, which, at standard atmospheric pressure, occupies a gaseous volume of about 1 L. Based on these findings, the researchers proposed intrapulmonary, endotracheal, or endobronchial administration of WAHPSs to rapidly oxygenate blood via the lungs in cases of severe acute respiratory obstruction due to asphyxia from sputum or blood. In experimental models of severe acute asphyxia induced by sputum or blood, a single intrapulmonary, endotracheal, or endobronchial injection of WAHPS transformed colloidal masses in the respiratory tract into soft white oxygen foam within 1–2 seconds, initiating blood oxygenation and fully resolving hypoxemia within 12 seconds. These theoretical and experimental results indicate that intrapulmonary, endotracheal, and endobronchial WAHPS injections could serve as an alternative to gaseous oxygen in mechanical ventilation or extracorporeal membrane oxygenation for treating patients with severe acute respiratory obstruction and hypoxemia.</p></abstract><trans-abstract xml:lang="ru"><p>В начале XXI века профессор Александр Ураков с командой коллег из России открыл кислород продуцирующие антигипоксанты и способ устранения ишемии и/или гипоксии тканей с помощью инъекции в них раствора этих лекарственных средств. При разработке указанного научного направления было получено около 40 патентов на изобретения. Показано, что группа кислород-продуцирующих антигипоксантов представляет собой тёплые щелочные растворы перекиси водорода (warm alkaline hydrogen peroxide solutions, WAHPSs), которые при инъекции в мокроту, слизь, гной, кровь и многие другие ткани быстро превращают их в мягкую кислородную пену. Дело в том, что эти и многие другие ткани нашего организма содержат фермент каталазу, которая в щелочной среде в условиях гипертермии в миллионы раз ускоряет процесс расщепления перекиси водорода на воду и молекулярный кислород. При каталазном расщеплении всей Н<sub>2</sub>О<sub>2</sub>, содержащейся в 100 мл раствора 3% перекиси водорода, образуется молекулярный кислород массой 1408 г, который при нормальном атмосферном давлении образует газ кислород, занимающий объём около 1 л. Опираясь на приведённые, данные российские исследователи предложили использовать WAHPSs путём внутрилёгочных, эндотрахеальных и эндобронхиальных инъекций для срочного насыщения крови кислородом через лёгкие при тяжёлой острой респираторной обструкции, вызванной асфиксией мокротой или кровью. В экспериментальных моделях тяжёлой острой асфиксии мокротой или кровью ими было показано, что однократная внутрилёгочная, эндотрахеальная или эндобронхиальная инъекция WAHPS через 1–2 с превращает в дыхательных путях коллоидные массы в пушистую кислородную пену белого цвета и начинает увеличивать оксигенацию крови, устраняя гипоксемию полностью не позже чем через 12 с. Приведённые результаты теоретических и экспериментальных исследований позволяют предположить, что внутрилёгочные, эндотрахеальные и эндобронхиальные инъекции WAHPs могут стать альтернативой газообразному кислороду, используемому при искусственной вентиляции лёгких и экстракорпоральной мембранной оксигенации, в борьбе за жизнь пациентов с тяжёлой острой респираторной обструкцией и гипоксемией.</p></trans-abstract><kwd-group xml:lang="en"><kwd>asphyxia</kwd><kwd>respiratory obstruction</kwd><kwd>hypoxemia</kwd><kwd>intrapulmonary injection</kwd><kwd>endobronchial injection</kwd><kwd>oxygen</kwd><kwd>antihypoxants</kwd><kwd>hydrogen peroxide</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>асфиксия</kwd><kwd>респираторная обструкция</kwd><kwd>гипоксемия</kwd><kwd>внутрилёгочная инъекция</kwd><kwd>эндобронхиальная инъекция</kwd><kwd>кислород</kwd><kwd>антигипоксанты</kwd><kwd>перекись водорода</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This research was part of State Assignment FGWG-2025-0020 "Search for molecular targets for pharmacological intervention in addictive and neuroendocrine disorders aimed at creating new pharmacologically active substances acting on central nervous system (CNS) receptors" of the Ministry of Science and Higher Education of Russia</funding-statement><funding-statement xml:lang="ru">Исследование выполнено в рамках государственного задания Минобрнауки России FGWG-2025-0020 «Поиск молекулярных мишеней для фармакологического воздействия при аддиктивных и нейроэндокринных нарушениях с целью создания новых фармакологически активных веществ, действующих на рецепторы ЦНС»</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Akoumianaki E, Vaporidi K, Bolaki M, et al.
