Patients with COPD have similar change of VC and its componentsas the normal subjects after breathing heliox, but the increased rate of ERV is much higher, and this is possibly due Objective:To the chronic overexpansion of pulmonary alveolus. The decreased rate of IC is smaller in COPD patients than that in the normal subjects.
结论COPD患者呼吸He-O2后VC及其组成有健康人相类似的反应，不同的是ERV的增幅比率较健康人要大得多，这可能与COPD肺泡长期处于膨胀状态有关，但IC的减少率又比健康人要小，呼吸He-O2后IC何以会减少以及COPD组与对照组间的变化率何以存在显著差异？
