Nutritional support is an important aspect of care in hospitalized patients, especially those receiving mechanical ventilation. While nutritional assessments can help guide the clinician in determining appropriate caloric intake requirements and refeeding schedules, few tools exist to evaluate the consequences of over- or underfeeding. Metabolic assessment using indirect calorimetry is a new method of nutritional assessment for use at the bedside of the weaning patient. The data obtained from a metabolic assessment can be used to adjust formulas and total caloric intake as well as differentiate between dead space and elevated carbon dioxide production as reasons for persistent hypercarbia.
营养支持是住院患者护理的一个重要方面，尤其是那些接受机械通气的患者。虽然营养评估有助于指导临床医生确定适当的热量摄入需求和重新喂养计划，但用于评估喂养过多或过少后果的工具却很少。使用间接测热法进行代谢评估是一种用于撤机患者床边的新营养评估方法。从代谢评估中获得的数据可用于调整配方和总热量摄入，以及区分无效腔和二氧化碳生成增加作为持续高碳酸血症的原因。
