Дыхание КГС проводили при концентрации газов: O2 – 30 %, He – 70 %; температура КГС на выходе из нагревателя +95 оС (при поступлении пациенту – до +65 оС). Показатели кровотока в МЦР регистрировали ультразвуковым высокочастотным допплерографом, датчиком с частотой 20 МГц на ногтевом валике большого пальца руки.</p></sec><sec><title>Результаты</title><p>Результаты. В ходе исследования: на ИВЛ показатели кровотока в МЦР у пациентов носили вариативный характер. Увеличение скорости кровотока в МЦР происходило за счет притока крови по артериолярному звену вследствие высоких значений частоты сердечных сокращений (ЧСС) (до 100 уд./мин), что составляло от 0,741 см/с до 2,428 см/с в разные дни наблюдения. Показатель периферического сопротивления кровотоку (PI) был высокий, соответствовал 1,332, в некоторые дни его значение возрастало на 13,7–26,7 %. Показатели капиллярного кровотока были на уровне низких скоростей – в среднем 0,181 см/с. При терапии КГС сразу после сеанса происходило увеличение скорости кровотока во всех звеньях МЦР: в артериолярном и капиллярном на 7 %, в венулярном почти в 3 раза относительно первичного исследования. Снижались индексы: сопротивления периферического кровотока PI – с 1,56 до 1,155 и тонуса сосудов RI – с 0,87 до 0,714. Положительный эффект терапии КГС отмечали через 30 мин, 60 мин и в последующие дни мониторинга МЦР.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>The aim</title><p>The aim. To perform a comparative analysis of microcirculatory bed (MCB) response in patients with viral pneumonia (COVID-19), severe course, aggravated by arterial hypertension on artificial lung ventilation (ALV) and thermal oxygen-helium mixture (OHM) therapy.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. 9 patients were on mask ALV and 13 received OHM therapy. The OHM therapy was performed at gas concentration: O2 – 30 %, He – 70 %; the OHM temperature at the heater output was +95 оС (patients received it with t= up to +65 оС). The blood flow parameters in the MCB were recorded by ultrasound dopplerograph, 20 MHz sensor on the nail shaft of the thumb.</p></sec><sec><title>Results</title><p>Results. The study has shown that the blood flow parameters in MCB were variable in patients on ALV. The increase in the blood flow velocity in MCB was due to blood inflow through the arteriolar link as a result of high values of HR (up to 100 beats/min), which ranged 0.741 – 2.428 cm/s on different days of observation. The PI index was high – 1.332 , some days its value increased by 13.7–26.7 %. Capillary blood flow indicators were low and averaged 0.181 cm/s. After OHM therapy, the blood flow velocity increased in all links of MCB: in the arteriolar and capillary by 7 %, in the venular almost 3 times as compared to the primary study. The PI index decreased from 1.56 to 1.155, vascular tone RI from 0.87 to 0.714. The positive effect of OHM therapy was observed after 30 min, 60 min and on subsequent days of MCB monitoring. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>кислородно-гелиевая терапия</kwd><kwd>искусственная вентиляция легких</kwd><kwd>микроциркуляторное русло</kwd><kwd>ультразвуковое исследование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>oxygen-helium mixture</kwd><kwd>helium-oxygen therapy</kwd><kwd>artificial lung ventilation</kwd><kwd>microcirculatory bed</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">Varga Z, Flammer AJ, Steiger P, Haberecker M, Andermatt R, Zinkernagel AS, Mehra MR, Schuepbach RA, Ruschitzka F, Moch H.
