При наблюдении за пациентами в постковидный период показано, что у части из них сохраняется широкий спектр жалоб – одышка, усталость, утомляемость, мышечная слабость, нарушения сна, кашель, сердцебиение, что способствовало появлению нового термина «постковидная болезнь». С целью выявления причин жалоб у перенесших COVID-19 пациентов необходимо проводить функциональную диагностику системы дыхания.</p><p>Целью исследования явилась оценка динамики функциональных показателей системы дыхания через 4 мес. после госпитализации по поводу COVID-19.</p><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование были включены пациенты (n = 31: 26 (84 %) – мужчины; средний возраст – 49 лет), перенесшие COVID-19. В рамках исследования проводились традиционные легочные функциональные тесты (спирометрия, бодиплетизмография, исследование диффузионной способности легких по монооксиду углерода (DLCO) и импульсная осциллометрия (ИОС).</p></sec><sec><title>Результаты</title><p>Результаты. Во время 1-го визита в среднем по группе показатели легочных функциональных тестов и ИОС составляли нормальные значения, кроме DLCO, которая была снижена у 77 % пациентов в легкой (на границе с умеренной) степени. Во время 2-го визита (через 102 дня после 1-го) в среднем по группе нарушение DLCO сохранялось у 58 %. При сравнительном анализе изучаемых показателей во время 1-го и 2-го визитов выявлено статистически значимое увеличение спокойной и форсированной жизненной емкости легких (ФЖЕЛ) и объема форсированного выдоха за 1-ю секунду (ОФВ1), общей емкости легких (ОЕЛ), DLCO, а также снижение соотношений ОФВ1 / ФЖЕЛ и остаточного объема легких / ОЕЛ при повторном исследовании.</p></sec><sec><title>Заключение</title><p>Заключение. У пациентов, перенесших COVID-19, через 4 мес. после выписки из стационара отмечается статистически значимое улучшение вентиляционной функции и DLCO. Целесообразно проводить оценку функциональных показателей системы дыхания в постковидный период с целью выявления и своевременной коррекции нарушений.</p></sec></abstract><trans-abstract xml:lang="en"><p>The end of the acute period of COVID-19 does not mean complete recovery. Observation of patients in the post-COVID-19 period showed that a significant number of people experience shortness of breath, fatigue, muscle weakness, sleep disorders, cough, palpitations, so the term post-COVID-19 syndrome was coined. The examination to identify the causes of complaints of COVID-19 convalescents should include lung function assessment.</p><p>The aim of the study was to assess the dynamics of lung function 4 months after hospitalization for COVID-19.</p><sec><title>Methods</title><p>Methods. 31 patients (26 males, the median age was 49 years) underwent traditional pulmonary function tests (PFTs) (spirometry, body plethysmography, test of diffusing lung capacity) and impulse oscillometry (IOS). Results. During the 1st visit, the average PFTs and IOS parameters were within the normal range in the whole group, apart from the diffusing lung capacity (DLCO), which was reduced mildly (on the border with moderate) in 77% of patients. During the 2nd visit, which was conducted on average 102 days after the 1st one, 58% of patients demonstrated abnormal lung diffusion capacity. The second assessment revealed a statistically significant increase in the slow and forced vital capacity (VC and FVC), the forced exhalation volume in 1 second (FEV1), total lung capacity (TLC), DLCO, and a decrease in the ratio of FEV1/FVC and the residual lung volume to TLC ratio.</p></sec><sec><title>Conclusion</title><p>Conclusion. Post-COVID-19 patients show a statistically significant improvement of their lung function 4 months after hospital discharge. A systematic follow-up is essential for such patients to detect lung function abnormalities and correct them.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>пост-COVID-19</kwd><kwd>спирометрия</kwd><kwd>диффузионная способность легких</kwd><kwd>импульсная осциллометрия</kwd><kwd>новая коронавирусная инфекция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lung function</kwd><kwd>post-COVID-19</kwd><kwd>spirometry</kwd><kwd>diffusion capacity</kwd><kwd>impulse oscillometry</kwd><kwd>new coronavirus infection</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">Ahmed H., Patel K., Greenwood D.C. et al.
