В 1 группу вошли 19 пациентов ХОБЛ, перенесших COVID-19, во 2 группу – 20 пациентов ХОБЛ. Исследование проведено через 3 месяца после перенесенного COVID-19. Результаты исследования показали наибольшее снижение высоты стояния купола диафрагмы в 1-ой группе (р=0,001). Экскурсия диафрагмы при спокойном дыхании была увеличена в обеих группах, во 2-ой группе показатель был на 12% больше, чем в 1 группе. Скорость экскурсии диафрагмы на вдохе и выдохе при спокойном и форсированном дыхании в обеих группах была достоверно увеличена по сравнению с контрольной группой. При этом в 1-ой группе скорость экскурсии диафрагмы на выдохе была выше на 49%. В обеих группах, по сравнению с контрольной группой, толщина мышечной части диафрагмы на вдохе и выдохе при спокойном дыхании была достоверно выше, но различий между группами не наблюдалось. Расчет фракции утолщения мышечной части диафрагмы позволяет точнее оценить сократительную способность диафрагмальной мышцы. При спокойном дыхании этот показатель был снижен в среднем на 23,9% (р=0,01) в обеих группах, при форсированном дыхании   на 35,8% (р=0,001) по сравнению с контрольной группой, что свидетельствует о начальном развитии слабости дыхательных мышц диафрагмы у пациентов, перенесших COVID-19. Таким образом, изучение функциональной активности диафрагмы дает возможность раннего выявления усталости и слабости мышц диафрагмы, что позволит открыть новые возможности профилактики и диагностики развития дыхательной недостаточности, своевременной коррекции установленных нарушений.</p></abstract><trans-abstract xml:lang="en"><p>For the purpose of ultrasound assessment of the functional state of the diaphragm inpatients with COPD who had suffered from COVID-19, 39 patients with COPD complicated by compensated CHL were examined. Group 1 included 19 patients with COPD who had suffered from COVID-19, group 2 included 20 patients with COPD. The study was conducted 3 months after contracting COVID-19. The results of the study showed the greatest decrease in the height of the diaphragm dome in group 1 (p = 0.001). The excursion of the diaphragm during quiet breathing was increased in both groups; in group 2 the indicator was 12% higher than in group 1. The rate of excursion of the diaphragm during inhalation and exhalation during quiet and forced breathing in both groups was significantly increased compared to the control group. Moreover, in group 1, the rate of exhalation of the diaphragm during exhalation was 49% higher. In both groups, compared with the control group, the thickness of the muscular part of the diaphragm during inhalation and exhalation during quiet breathing was significantly higher, but no differences were observed between the groups. Calculation of the fraction of thickening of the muscular part of the diaphragm allows a more accurate assessment of the contractility of the diaphragm muscle. With quiet breathing, this indicator   was reduced by an average of 23.9% (p = 0.01) in both groups, with forced breathing by 35.8% (p = 0.001) compared to the control group, which indicates the initial development weakness of the respiratory muscles of the diaphragm in patients who have had COVID-19. Thus, studying the functional activity of the diaphragm makes it possible to early detect fatigue and weakness of the diaphragm muscles, which will open up new opportunities for the prevention and diagnosis of the development of respiratory failure, and timely correction of established disorders.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хроническая обструктивная болезнь легких</kwd><kwd>COVID-19</kwd><kwd>дисфункция диафрагмы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic obstructive pulmonary disease</kwd><kwd>COVID-19</kwd><kwd>diaphragm dysfunction</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">Будневский А.В., Авдеев С.Н., Овсянников Е.С., Савушкина И.А., Шкатова Я.С., Шишкина В.В.
