Metabolic gas exchange and respired minute volume were measured on 37 occasions in 9 normal adults on exercise and at rest, using the concentration of an injected gas, argon, as a measure of flow. These measurements were compared with simultaneous Douglas bag collections in which volumes were determined with a dry gas meter. The two types of measurements agreed within +/- 5%. It was concluded that this technique, designed for the remote monitoring of unconscious patients was suitable for a wide variety of clinical and experimental situations.
在9名正常成年人休息和运动时，共进行了37次代谢气体交换和呼吸分钟量的测量，使用注入气体氩的浓度作为流量的度量。这些测量结果与同时进行的道格拉斯袋收集法进行了比较，后者使用干式气体流量计测定体积。两种测量类型的结果在±5%的范围内相符。得出的结论是，这种为远程监测昏迷患者而设计的技术适用于广泛的临床和实验情况。
