A system of instrumentation for continuous measurement of gaseous metabolism and minute volume (VI) in the human newborn is described. O2 uptake and CO2 production are measured by open-circuit techniques utilizing a Servomex OA184 differential paramagnetic O2 analyzer and a BEckman LB-2 infrared CO2 analyzer. VI is measured with bias-flow pneumotachometry. Bench performance is described, methodological errors are defined, and clinical data are presented. The instrumentation is capable of safe, accurate, and continuous measurement of respiratory and metabolic variables in low-birth-weight infants.
本文描述了一种用于连续测量新生儿气体代谢和每分通气量（VI）的仪器系统。采用开路技术，利用Servomex OA184型差动顺磁氧分析仪和贝克曼LB - 2型红外二氧化碳分析仪测量氧摄取量和二氧化碳产生量。每分通气量通过偏流呼吸流速计测量。阐述了该仪器的实验台性能，界定了方法学误差，并给出了临床数据。该仪器能够安全、准确且连续地测量低体重婴儿的呼吸和代谢变量。
