Carbon monoxide (CO) in expired breath is a common strategy for verifying smoking abstinence. The purpose of this investigation was to determine the comparability of two carbon monoxide (CO) analyzers: the commonly used Ecolyzer Series 2000 analyzer versus the new, highly portable, and less expensive Ecolyzer Model 210. Fifty-eight CO readings were obtained from 29 subjects (17 smokers, 12 nonsmokers) and analyzed on both systems simultaneously. Results indicated that the analyzers yielded highly comparable values for both smokers and nonsmokers. Moreover, the correlation between the two units' readings was very high (r = .92, p less than .001). There was, however, a significant analyzer by sex interaction with the Series 2000 analyzer yielding higher values for males. Overall, it was concluded that the Series 210 analyzer is a highly accurate and cost-effective instrument.
呼出气体中的一氧化碳(CO)是验证戒烟情况的常用方法。本研究的目的是确定两种一氧化碳(CO)分析仪的可比性:常用的Ecolyzer 2000系列分析仪与新型、高度便携且价格较低的Ecolyzer 210型分析仪。从29名受试者(17名吸烟者,12名非吸烟者)中获取了58个CO读数,并同时在两个系统上进行分析。结果表明,这两种分析仪对吸烟者和非吸烟者都产生了高度可比的值。此外,两个仪器读数之间的相关性非常高(r = 0.92,p小于0.001)。然而,存在分析仪与性别的显著交互作用,2000系列分析仪对男性产生的值更高。总体而言,得出的结论是,210系列分析仪是一种高度准确且经济高效的仪器。
