Степень одышки оценивали в соответствии с модифицированной шкалой Медицинского исследовательского совета (Medical Research Council — MRC). Степень ОП оценивали по 5-балльной шкале в зависимости от ОП, выраженного в % от контрольного дыхательного объема, и от положения тела.При применении NEP-метода ОП было выявлено у 6 больных в положении сидя и лежа и у 3 больных — только в положении лежа. При применении сравнительного метода ОП было выявлено у 20 больных. При проведении множественного регрессионного анализа ОП лучше всего прогнозировал степень одышки.Таким образом, большинство больных муковисцидозом не имеют ОП при спокойном дыхании; выявление ОП может быть полезно в оценке степени одышки, а применение сравнительного метода для оценки ОП может приводить к ошибочным результатам.</p></abstract><trans-abstract xml:lang="en"><p>The negative expiratory pressure (NEP) technique is a simple, rapid, noninvasive method for detecting expiratory flow limitation (FL) during spontaneous breathing.The purpose of this study was to assess the prevalence of FL during resting breathing in adult cystic fibro­sis (CF) patients in both the seated and supine positions; and whether FL is associated with dyspnea.We studied 34 CF patients with the NEP technique and conventional method, based on comparison of tidal and maximal expiratory flow-volume curves. Dyspnea was assessed according to the modified Medical Research Council (MRC) scale. The degree of FL was assessed in terms of a 5-point score according to % control tidal volume encompassed by FL and body position.With NEP, 6 patients were FL in the seated/supine positions and 3 were FL only in the supine position. By contrast, 20 patients were classified as FL with the conventional method. In a multiple regression analysis FL was the best predictor in assessing the severity of dyspnea.In conclusion, most stable CF patients do not exhibit tidal FL during resting breathing; detection FL may be useful in the evaluation of dyspnea; and the conventional method for assessing FL may lead to erroneous con­clusions.</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">Авдеев С.Н., Чучалин А.Г.
