描述了一种用于连续测量人类新生儿气体代谢和微小体积(VI)的仪器系统。利用Servomex OA184差示顺磁O2分析仪和Beckman LB-2红外二氧化碳分析仪，通过开路技术测量氧气摄取和二氧化碳产生。VI用偏流气动测速仪测量。描述了试验台的性能，定义了方法学错误，并提供了临床数据。该仪器能够安全、准确和连续地测量低出生体重儿的呼吸和代谢变量。
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.
