The relation between self-assessed and objective measures of inhalation was studied in 75 smokers who assigned themselves to one of four inhalation categories, and also estimated inhalation using a rating scale. The analysis of presmoking carbon monoxide concentration in expired air, and of the rise in carbon monoxide concentration over smoking, provided an objective measure of inhalation. These was a weak but significant correlation between self-rated inhalation and rise in carbon monoxide, but no correlation with the longer-term exposure measured by presmoking levels of carbon monoxide. Differences in exposure to carbon monoxide according to self-assessed inhalation category were non-significant. It is concluded that neither subjective measure of inhalation contributes usefully to the estimation of smoke exposure among smokers who inhale.
对75名吸烟者进行了自我评估与吸入客观测量之间关系的研究。这些吸烟者将自己归入四种吸入类别之一，并使用评分量表估计吸入情况。通过分析呼气中吸烟前一氧化碳浓度以及吸烟过程中一氧化碳浓度的上升情况，得出了吸入的客观测量结果。自我评定的吸入量与一氧化碳浓度上升之间存在微弱但显著的相关性，但与吸烟前一氧化碳水平所测量的长期暴露量无关。根据自我评估的吸入类别，一氧化碳暴露差异不显著。得出的结论是，对于吸入的吸烟者，两种吸入的主观测量方法均无助于估计烟雾暴露情况。
