Impulse oscillometry (IOS) is a force-free, easy-to-use tool for the detection of airway resistance. Compared with spirometry, IOS is more sensitive in detecting early abnormalities in chronic obstructive pulmonary disease (COPD), and IOS parameters have potential research value in identifying the progression of COPD and monitoring the effect of treatment. This review aimed to highlight the significant research findings of IOS in chronic obstructive pulmonary disease and to address the urgent issue that need to be resolved.
脉冲振荡技术（IOS）是一项无需用力、操作简单、用于检测气道阻力的工具。IOS相比肺通气功能检查可以较为敏感地识别慢性阻塞性肺疾病（简称慢阻肺）的早期异常，其参数在识别慢阻肺进展和监测治疗效果方面具有潜在的研究价值。本文主要综述IOS在慢阻肺领域的重要研究发现，并提出亟须解决的问题。.
