由于缺乏简单且价格亲民的肺功能仪，社区中慢性呼吸道疾病常常出现漏诊和延迟诊断的情况。PUS201P 是一款为解决这一问题而研发的便携式肺功能仪。
我们旨在验证 PUS201P 肺功能仪与传统耶格（Jaeger）肺功能仪测量结果的一致性。
在这项横断面研究中，我们随机招募了 202 名年龄大于 40 岁的受试者。对所有参与者均使用便携式肺功能仪和传统肺功能仪进行检测。我们比较了 PUS201P 设备与传统肺功能仪所测量的一秒用力呼气容积（FEV1）、用力肺活量（FVC）以及 FEV1/FVC 比值。通过计算皮尔逊相关系数和组内相关系数（ICC）来确认两种仪器测量结果的一致性。绘制布兰德-奥特曼（Bland–Altman）图来评估两种设备测量结果的一致性。
本研究共纳入 202 名参与者。便携式肺功能仪与传统肺功能仪所测量的 FEV1、FVC、FEV1/FVC 的 ICC 分别为 0.95（95%置信区间[CI]：0.94 - 0.96）、0.92（95% CI：0.90 - 0.94）、0.93（95% CI：0.91 - 0.95）。布兰德-奥特曼图显示，两种肺功能仪测量结果的平均差值始终处于 95%一致性界限内。
我们的研究结果表明，便携式肺功能仪与传统肺功能仪的测量结果具有良好的一致性和可重复性。该便携式肺功能仪是基层医疗环境中筛查和诊断慢性气道疾病的可靠工具。

The lack of simple and affordable spirometry has led to the missed and delayed diagnoses of chronic respiratory diseases in communities. The PUS201P is a portable spirometry developed to solve this problem. We aimed to verify the consistency of the PUS201P spirometer with conventional Jaeger spirometer. In this cross-sectional study, we randomly recruited 202 subjects aged > 40 years. Testing with the portable spirometry and conventional spirometry were performed on all participants. We compared forced expiratory volume in one second (FEV1), forced vital capacity (FVC), FEV1/FVC measured by the PUS201P device with the conventional spirometer. Pearson correlation coefficient and Interclass Correlation Coefficient (ICC) were assessed to confirm the consistency of the measures from two instruments. Bland–Altman graph was created to assess the agreement of the measures from two devices. 202 participants were included in this study. The ICC on FEV1, FVC, FEV1/FVC measured by the portable spirometer and the conventional spirometer were 0.95 (95% confidence interval [CI]: 0.94–0.96), 0.92 (95% CI: 0.90–0.94], 0.93 (95% CI: 0.91–0.95), respectively. The Bland–Altman plots showed that the mean difference between the measures from two spirometers are always located in the 95% limits of agreement. Our results support that the measures from the portable spirometer and the conventional spirometer have a good agreement and reproducibility. And the portable spirometer is a reliable tool to screen and diagnose chronic airway diseases in the primary care settings.
