Oscillometry devices (also termed forced oscillation technique) devices such as MasterScreen-IOS® (Jaeger, Hochberg, Germany) and MostGraph-01® (Chest, Tokyo, Japan) are useful for obtaining physiological assessments in patients with obstructive lung diseases, including asthma. However, as oscillometry measurements have not been fully compared between MasterScreen-IOS® and MostGraph-01® in patients with asthma, it is unknown whether there are differences in the measurements between the devices. This study aimed to determine whether there is any difference in oscillometry measurements obtained using the two devices in patients with asthma.
Oscillometry measurements obtained using MasterScreen-IOS® and MostGraph-01® were retrospectively evaluated in 95 patients with asthma at Juntendo University Hospital between October 2009 and November 2009.
There was a strong positive correlation in the measurements between the two devices. However, the values of R5, R20, ALX and Fres were lower when measured with MostGraph-01® than with MasterScreen-IOS®, and vice versa for the values of X5. The results were used in correction equations to convert oscillometry parameters measured using MasterScreen-IOS® to those measured using MostGraph-01®.
To our knowledge, this is the first report to compare MostGraph-01® and MasterScreen-IOS® devices using practical clinical data obtained in patients with asthma. The values obtained by both devices can be interpreted in a similar way, although there is slight variation. The conversion equations produced in this study may assist to compare the oscillometry measurements obtained by each of the two devices.
振荡测量设备（也称为强迫振荡技术），如 MasterScreen-IOS®（德国耶格公司）和 MostGraph-01®（日本光电公司），可用于获取阻塞性肺疾病患者（包括哮喘患者）的生理评估。然而，由于在哮喘患者中尚未对 MasterScreen-IOS®和 MostGraph-01®的振荡测量进行充分比较，因此尚不清楚这两种设备的测量值是否存在差异。本研究旨在确定在哮喘患者中使用这两种设备进行振荡测量时是否存在差异。
回顾性评估了 2009 年 10 月至 11 月期间在日本顺天堂大学医院就诊的 95 例哮喘患者使用 MasterScreen-IOS®和 MostGraph-01®获得的振荡测量值。
两种设备之间的测量值存在很强的正相关性。然而，与使用 MasterScreen-IOS®相比，MostGraph-01®测量的 R5、R20、ALX 和 Fres 值较低，而 X5 的值则相反。使用这些结果在校正方程中，将使用 MasterScreen-IOS®测量的振荡参数值转换为使用 MostGraph-01®测量的值。
据我们所知，这是第一篇使用从哮喘患者获得的实际临床数据比较 MostGraph-01®和 MasterScreen-IOS®设备的报告。虽然存在细微差异，但两种设备获得的值可以以相似的方式进行解释。本研究中生成的转换方程可能有助于比较两种设备获得的振荡测量值。
