The effect of tobacco smoking in a closed space on blood COHb saturation was investigated in a group of 21 smokers and 28 nonsmokers. Each of the smoking subjects smoked 6 cigarettes, starting a new one every 15 minutes. At the end of the experiments the mean CO concentration in the room was about 30 ppm, which is about normal for smoky rooms. The blood COHb saturation increased in the smoking group from 5.3 (2.1 SD) to 9.1 (2.1 SD)%. In the nonsmoking group the increase was from 1.6 (0.6 SD) to 2.2 (0.6 SD)%. The mean increase in nonsmoking group was as much as smoking one cigarette. Extrapolated to an eight hour period this suggests that a nonsmoking subject would inhale tobacco smoke equivalent to about five cigarettes.
在一组21名吸烟者和28名非吸烟者中，研究了在封闭空间内吸烟对血液中碳氧血红蛋白（COHb）饱和度的影响。每位吸烟受试者吸6支香烟，每15分钟点燃一支新烟。实验结束时，室内一氧化碳（CO）的平均浓度约为30 ppm，这在烟雾弥漫的房间中大致正常。吸烟组的血液COHb饱和度从5.3（标准差2.1）%增加到9.1（标准差2.1）%。在非吸烟组中，这一数值从1.6（标准差0.6）%增加到2.2（标准差0.6）%。非吸烟组的平均增加量相当于吸一支烟。推算到8小时的时间段，这表明一名非吸烟受试者吸入的烟草烟雾量相当于大约5支香烟。
