The forced oscillation technique (FOT) is a noninvasive method with which to measure respiratory system resistance and reactance during tidal breathing. Recently, its clinical application has spread worldwide with the expansion of commercially available broadband frequency FOT devices, including MostGraph and Impulse Oscillometry. An increasing number of reports have supported the usefulness of the FOT in the management of asthma and chronic obstructive pulmonary disease (COPD). However, the FOT is not a surrogate test for spirometry, but should be used complementarily. Furthermore, reference values are not necessarily available and the interpretation of some measured data is controversial. There is a need to update the international statement for not only technical aspects but also the clinical use of the FOT. In this review, we summarize the previously published studies and discuss how to use the FOT in a clinical setting.
强迫振荡技术（FOT）是一种在潮气呼吸期间测量呼吸系统阻力和电抗的非侵入性方法。近来，随着包括MostGraph和脉冲振荡法在内的商用宽带频率FOT设备的推广，其临床应用已在全球范围内得到普及。越来越多的报告支持FOT在哮喘和慢性阻塞性肺疾病（COPD）管理中的实用性。然而，FOT并非肺量计的替代测试，而应作为补充使用。此外，不一定有参考值，并且一些测量数据的解释存在争议。不仅需要更新关于FOT技术方面的国际声明，还需要更新其临床应用的声明。在本综述中，我们总结了先前发表的研究，并讨论了如何在临床环境中使用FOT。
