A comparative study has been carried out to investigate the performance of the hot-wire spirometer and the Rollingseal spirometer; the reproducibility of the data generated by an individual examiner; and the validity of data obtained by an "inexperienced examiner" using the hot-wire spirometer. The following results were obtained: 1. The experimental data given by the hot-wire spirometer were about 5-6% higher for FVC and FEV1, and about 10-12% higher for PFR, V50, and V25, respectively, when compared to the data generated by the Rollingseal spirometer. 2. The reproducibility of the data produced by the hot-wire spirometer operated by an "experienced examiner" was good, as the percent difference was about +/- 3%. 3. Reliable data were obtained with the spirometer even by an "inexperienced examiner" if he/she has gone through an on-site training concerning instrumentation and measurement methods for spirography.
已开展一项对比研究,以调查热线式肺活量计和滚动密封式肺活量计的性能;单个检查者生成数据的可重复性;以及“经验不足的检查者”使用热线式肺活量计获得数据的有效性。获得了以下结果:1. 与滚动密封式肺活量计生成的数据相比,热线式肺活量计给出的实验数据中,用力肺活量(FVC)和第一秒用力呼气量(FEV1)分别高出约5 - 6%,峰值呼气流速(PFR)、50%肺活量时的瞬间呼气流量(V50)和25%肺活量时的瞬间呼气流量(V25)分别高出约10 - 12%。2. 由“经验丰富的检查者”操作的热线式肺活量计所产生数据的可重复性良好,因为百分比差异约为±3%。3. 如果“经验不足的检查者”接受过有关肺量计仪器和测量方法的现场培训,使用该肺活量计也能获得可靠的数据。
