Fractional CO uptake was measured in 50 healthy men and women aged 18 to 65 years in the sitting and supine positions and during the steady state of treadmill exercise at four different workloads. The unwanted influence of respiratory frequency and ventilation on fractional uptake and the indirect effect of workload (via changes in total diffusing capacity) were taken into account, according to previous theoretical analysis, in formulating prediction equations. Correlations for the best equations were between 0.816 and 0.971. The extra precision they afford makes the fractional CO uptake a potentially useful clinical measurement, less prone to spurious results than conventional measurements of diffusing capacity.
对50名年龄在18至65岁之间的健康男性和女性进行了分数一氧化碳摄取量的测量，测量在坐姿、仰卧位以及在四种不同工作量的跑步机稳定运动状态下进行。根据先前的理论分析，在制定预测方程时考虑了呼吸频率和通气对分数摄取量的不良影响以及工作量的间接影响（通过总弥散能力的变化）。最佳方程的相关性在0.816至0.971之间。它们所提供的额外精度使得分数一氧化碳摄取量成为一种潜在有用的临床测量方法，与传统的弥散能力测量相比，更不易产生虚假结果。
