Целью работы явилась оценка респираторного импеданса и его составляющих; определение взаимосвязи этих параметров с параметрами, традиционно используемыми для оценки респираторной функции, у больных муковисцидозом. Спирометрия, общая бодиплетизмография и ИОС (Z, резистивный (R) и реактивный (X) его компоненты, резонансная частота (FR), площадь под кривой X (частота осцилляций) в частотном диапазоне 5 Гц — FR (AX) при спокойном дыхании) были проведены у 66 больных муковисцидозом, наблюдаемых в центре муковисцидоза взрослых на базе НИИ пульмонологии, Москва. У больных муковисцидозом были выявлены обструктивные нарушения (ОФВ1 — 57 %долж.) и гиперинфляция легких (ООЛ — 253 %долж., ФОЕ — 158 %долж., ООЛ/ОЕЛ — 52 %). При проведении ИОС было обнаружено увеличение R, которое имело частотную зависимость (R5 — 173 % долж., R20 — 140 %долж.) и снижение реактивного компонента X5 (–0,23 кПа / л–1 / с), что приводило к смещению резонансной частоты в более высокий частотный диапазон (FR — 18 Гц, AX — 1,38 кПа / л–1). Существует достоверная корреляционная зависимость между параметрами ИОС (FR, X20, R5, R20, AX) и главным показателем тяжести обструктивных нарушений (ОФВ1 — 0,74; 0,78; –0,42; –0,31 и –0,76 соответственно). Полученные данные продемонстрировали, что измерение респираторного импеданса позволяет оценить степень бронхиальной обструкции. ИОС не зависит от усилий пациента и может быть использован в клинической практике, в т. ч. у больных с тяжелыми респираторными нарушениями.</p></abstract><trans-abstract xml:lang="en"><p>Impulse oscillometry (IOS) measures the total respiratory system impedance (Z) at incremental frequencies during normal tidal breathing. Our aim was to establish the total respiratory impedance and how IOS measurements relate to conventional lung function indices in patients with cystic fibrosis (CF). Results from spirometry, static lung volumes and IOS (R, X, Z, resonant frequency (FR) and reactance area 5Hz — FR (AX)) were compared in 66 adult CF patients recruited from CF Care Centre of Moscow. Patients had airway obstruction (FEV1 = 57 % pred.), hyperinflation (RV = 253 % pred., FRC = 158 % pred., RV / TLC = 52 %). IOS demonstrated a frequency dependent increase in R (R5 = 173 % pred., R20 = 140 % pred.) and a decrease in X (X5 = –0,23 kPa/L / s) with a shift in FR to higher frequencies (FR = 18 Hz, AX = 1,4 kPa / L). There were significant correlations between FR, X20, R5, R20, AX and conventional lung function indices (FEV1 = – 0,74; 0,78; –0,42; –0,31 and –0,76 respectively). The data indicate that measurement of reactance and FR may reflect the degree of airway obstruction. IOS is an effort independent measurement that could be used in clinical routine especially in patients with severe lung diseases.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Амелина Е.Л., Черняк А.В., Черняев А.Л.
