IC is the standard for determining energy expenditure in critically ill patients. The measured REE is an objective, patient-specific caloric reference that serves as the most accurate method of determining energy expenditure. Protocols addressing IC methodology are necessary to ensure technical accuracy and clinically useful results. The measured REE should be the caloric target without the addition of stress or activity factors for nutrition support regimens in the ICU. The RQ should be used primarily as an indicator of test validity. Optimal nutrition intervention requires continuous evaluation of all pertinent clinical data and careful monitoring of each patient's response to therapy.
间接测热法是确定危重症患者能量消耗的标准方法。所测得的静息能量消耗是一个客观的、针对患者的热量参考值，是确定能量消耗最准确的方法。规范间接测热法的操作流程对于确保技术准确性和获得临床有用的结果是必要的。在重症监护病房，所测得的静息能量消耗应作为营养支持方案的热量目标，无需增加应激或活动因素。呼吸商主要应用于检验测试的有效性。最佳营养干预需要持续评估所有相关临床数据，并仔细监测每位患者对治疗的反应。
