We have read with interest the official European Respiratory Society technical standards for Global Lung Function Initiative (GLI) reference lung volumes [1], and we welcome the user-friendly online computation module that facilitates translation of spirometry, transfer factor and lung volume variables into % predicted and z-scores [2]. The latter allows lung function researchers to stay up-to-date with the latest normative values of variables that are being measured in the routine lung function lab, while awaiting upgrades of their laboratory equipment to the latest reference values for carbon monoxide transfer factor (25 September 2020 update) or to the newly published lung volumes.

我们饶有兴趣地阅读了欧洲呼吸学会关于全球肺功能倡议 (GLI) 参考肺容积的官方技术标准 [1]，我们欢迎用户友好的在线计算模块，该模块有助于将肺活量、转移因子和肺容积变量转换为% 预测和 z 分数 [2]。后者使肺功能研究人员能够了解在常规肺功能实验室中测量的变量的最新规范值，同时等待他们的实验室设备升级到一氧化碳转移因子的最新参考值 (25 2020 年 9 月更新）或新发布的肺卷。
