In particular, approaches to determination of fluid responsiveness using Doppler-estimated blood flow in peripheral arteries are discussed. The reliability and accuracy of these parameters are substantiated by their comparison with the parameters obtained by prepulmonary and transpulmonary thermodilution methods. The technicalities of ultrasound examination of the abovementioned parameters are considered.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>волемический статус</kwd><kwd>чувствительность к инфузионной нагрузке</kwd><kwd>гиперволемия</kwd><kwd>венозный застой</kwd><kwd>ультразвук</kwd></kwd-group><kwd-group xml:lang="en"><kwd>intravascular volume status</kwd><kwd>fluid responsiveness</kwd><kwd>hypervolemia</kwd><kwd>venous congestion</kwd><kwd>ultrasound</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">авторы заявляют о финансировании проведенного исследования из собственных средств.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Кузьков В.В., Фот Е.В., Сметкин А.А., Лебединский К.М., Киров М.Ю.
