An original metabolic calculator is realized with common and fiable transducers: a "microgaz Roche Kontron 7640" gives the PiO2-PeO2 and PeCO2 (Clark and Stow Severinghaus electrods), a pneumotachograph Gould 17212 (or the reliable integrated flow meter of the respirator) gives the expiratory minute volume. These values are inserted in an micro computer (Sharp PC 1261). The soft is wrote so that results are not altered when high FiO2 are used. Consumption of lipids and glucids is displayed in percentage when diuresis and urea values are entered. This device is compared with a well known expenditure monitor: Deltatrac (Datex): simultaneous measures are carried out in patients with miscellaneous diseases (15 series of 10 measures). Regression curves appear to be very reliable, as well for VO2(r = 0.98), VCO2 (r = 0.94) energy expenditure (0.97) as for R.Q (r = 0.77).
一台“罗氏康特龙7640微量气体分析仪”可测量动脉血氧分压 - 呼气末氧分压和呼气末二氧化碳分压（克拉克电极和斯托 - 西弗林豪斯电极），一台古尔德17212型呼吸流速计（或呼吸机可靠的集成流量计）可测量呼气分钟量。这些数值被输入一台微型计算机（夏普PC 1261）。软件编写使得在使用高氧浓度时结果不会改变。当输入尿量和尿素值时，脂肪和糖类的消耗量以百分比形式显示。该设备与一种知名的能量消耗监测仪：德尔塔Trace（Datex）进行了比较：在患有各种疾病的患者中进行了同步测量（15组，每组10次测量）。回归曲线似乎非常可靠，对于氧耗量（r = 0.98）、二氧化碳生成量（r = 0.94）、能量消耗（r = 0.97）以及呼吸商（r = 0.77）都是如此。
