Abstract

Non-invasive substrate utilization using expiratory gases is a cost effective and informative procedure in the nutritional management of the critically ill patient. In addition, the effect of feeding on the respiratory system depends on the substrates utilized and therefore provides information for an optimal regimen in nutritional support. However, metabolic systems to assess substrate utilization are often expensive. Hence, the program described here, in combination with the necessary instrumentation (ventilation meter, O2 and CO2 analyzer), will allow a rapid and quantitatively reliable assessment of substrate utilization.

摘要

利用呼出气体进行无创性底物利用评估，对于危重症患者的营养管理而言，是一种经济高效且信息丰富的方法。此外，喂养对呼吸系统的影响取决于所利用的底物，因此可为营养支持的优化方案提供信息。然而，评估底物利用的代谢系统通常价格昂贵。因此，本文所述的程序，结合必要的仪器设备（通气计、氧气和二氧化碳分析仪），将能够对底物利用进行快速且定量可靠的评估。
