描述了一种测量人在休息、中等工作期间或重工作期间的耗氧量的系统。从合适的呼吸器测量和采样的呼出空气被收集在金属化的聚乙烯袋中。二氧化碳在几个小时内不会从这些地方显著扩散。为了进行分析，气体依次通过干燥柱、顺磁氧分计和热导CO2计进行提取。可直接分析肺泡空气。给出了适用于计算机程序的呼吸交换和代谢混合物的计算表。
A system is described for measuring the oxygen consumption of men at rest, during moderate work, or during heavy work. Expired air, measured and sampled from a suitable respirometer, is collected in metalized polyethylene bags. Carbon dioxide does not diffuse measurably from these in several hours. For analysis, gas is drawn successively through a drying column, a paramagnetic oxygen meter, and a thermal conductivity CO2 meter. Alveolar air may be analyzed directly. Calculation sheets suitable for computer programs are given for respiratory exchange and the metabolic mixture.
