Previous publications on the effects of low levels of carbon monoxide (CO) on human vigilance performance have found conflicting results. While several studies have found statistically reliable effects, none have gone unchallenged. This article presents a critical review of the literature and the results of a study employing 52 human male subjects performing a numeric monitoring task. CO levels were 0, 100, and 200 ppm which produced mean carboxyhemoglobin levels 0.01, 4.61 and 12.62 percent respectively. No CO-exposure levels produced any effect on vigilance performance. The power of the statistical test for CO effects was shown to be quite high, even for fairly trivial possible decrements of performance.
先前关于低水平一氧化碳（CO）对人体警觉性能影响的出版物得出了相互矛盾的结果。虽然有几项研究发现了具有统计学意义的可靠影响，但没有一项研究没有受到质疑。本文对相关文献进行了批判性综述，并展示了一项针对52名男性受试者进行数字监测任务的研究结果。一氧化碳水平分别为0、100和200 ppm，相应的平均碳氧血红蛋白水平分别为0.01%、4.61%和12.62%。没有任何一氧化碳暴露水平对警觉性能产生影响。结果表明，即使对于相当轻微的可能的性能下降，针对一氧化碳影响的统计检验效力也相当高。
