背景在野外行走测试期间很少测量呼吸频率，因为当前使用面罩的监测系统对于老年人来说很麻烦。为了有效的临床应用，我们的目的是在年轻人和慢性阻塞性肺病 (COPD) 患者的 6 分钟步行测试 (6MWT) 中验证使用可穿戴应变传感器的新型呼吸监测器。方法该研究包括从三家医院自愿招募的年轻人和稳定期 COPD 患者。 6MWT 期间的呼吸频率由应变传感器和鼻二氧化碳计测量。总呼吸频率由二氧化碳计测量。采用 Bland-Altman 方法估计呼吸频率的平均一致性极限。 结果 总共分析了 23 名年轻人（年龄 = 23.1 ± 3.7，平均值 ± SD）和 50 名 COPD 患者（年龄 = 75.2 ± 7.2，%FEV1 = 59.1 ± 19.7）。在整个测试期间，测量的总呼吸频率平均为 252 ± 46 次，COPD 患者的总呼吸频率高于年轻人（平均差 = -3.349，p< 0.0013）。应变传感器和二氧化碳计之间的呼吸频率平均差异为-0.28（95%CI：0.75至0.20），一致性极限范围为-4.1至3.6。一致性极限的 CI 包括等效极限（4 次/分钟）。 结论 采用可穿戴传感器的新型呼吸监测仪在 6MWT 中在年轻人和 COPD 患者中均达到了目标准确度。
BackgroundBreathing frequency is rarely measured during a field walking test since the current monitoring system using a face mask is cumbersome for older adults. For effective clinical application, we aimed to validate the new respiratory monitor using wearable strain sensors during a 6-min walk test (6MWT) in young adults and patients with chronic obstructive pulmonary disease (COPD).MethodsThe study included young adults and patients with stable COPD voluntarily recruited from three hospitals. Breathing frequency during 6MWT were measured by the strain sensor and a nasal capnometer. Total breathing frequencies were measured by the capnometer. The Bland–Altman method was used to estimate the mean limit of agreement for breathing frequency.ResultsA total of 23 young adults (age = 23.1 ± 3.7, mean ± SD) and 50 patients with COPD (age = 75.2 ± 7.2, %FEV1 = 59.1 ± 19.7) were analyzed. During the entire test period, the total breathing frequencies were measured based on an average of 252 ± 46 breaths, and the total breathing frequency was higher in patients with COPD than in young adults (mean difference = −3.349,p< 0.0013). The mean difference in breathing frequency between the strain sensors and capnometer was −0.28 (95%CI: 0.75 to 0.20), and the limit of agreement ranged from −4.1 to 3.6. The CI of the limit of agreement included the limit of equivalence (4 counts/min).ConclusionsThe novel respiratory monitor with wearable sensors achieved the target accuracy in both young adults and patients with COPD in the 6MWT.
