abstract
electronic noses (cyanose 320), artificial sensor systems generally consisting of chemical sensor arrays for the detection of volatile compound profiles, have potential applications in respiratory medicine. we assessed within-day and between-day repeatability of an e-nose made from 32 sensors in patients with stable chronic obstructive pulmonary disease (copd). we also compared between-day repeatability of an e-nose, fraction of exhaled nitric oxide (feno) and pulmonary function testing. within-day and between-day repeatability for the e-nose was assessed in two breath samples collected 30 min and seven days apart, respectively. repeatability was expressed as an intraclass correlation coefficient (icc). all sensors had icc above 0.5, a value that is considered acceptable for repeatability. regarding within-day repeatability, icc ranged from 0.75 to 0.84 (mean = 0.80 ± 0.004). sensors 6 and 19 were the most reproducible sensors (both, icc = 0.84). regarding between-day repeatability, icc ranged from 0.57 to 0.76 (mean = 0.68 ± 0.01). sensor 19 was the most reproducible sensor (icc = 0.76). within-day e-nose repeatability was greater than between-day repeatability (p < 0.0001). between-day repeatability of feno (icc = 0.91) and spirometry (icc range = 0.94–0.98) was greater than that of e-nose (mean icc = 0.68). in patients with stable copd, the e-nose used in this study has acceptable within-day and between-day repeatability which varies between different sensors.
电子鼻(cyranose 320)是一种人工传感器系统，通常由化学传感器阵列组成，用于检测挥发性化合物分布，在呼吸医学中有潜在的应用。我们在一天内和两天之间评估了由32个传感器制成的电子鼻在慢性阻塞性肺病(copd)稳定患者中的重复性。我们还比较了电子鼻的白天重复性、呼出的一氧化氮(feno)分数和肺功能测试。在一天之内和两天之间，分别在30分钟和7天间隔采集的两个呼吸样本中评估电子鼻的可重复性。重复性用组内相关系数(icc)表示。所有传感器的icc都高于0.5，这一数值被认为是可接受的重复性。关于日间重复性，icc范围为0.75至0.84(平均值=0.80±0.004)。传感器6和19是可重复性的传感器(两者，icc=0.84)。关于日间重复性，icc范围为0.57至0.76(平均值=0.68±0.01)。传感器19是可重复性的传感器(icc=0.76)。在一天内，电子鼻的重复性大于两天之间的重复性(p<0.0001)。feno(icc=0.91)和肺活量测定(icc范围=0.94-0.98)的日间重复性高于e鼻(平均icc=0.68)。对于稳定型慢性阻塞性肺病患者，本研究中使用的电子鼻在一天内和两天之间具有可接受的重复性，不同传感器之间的重复性不同。
