From: Routine use of indirect calorimetry in critically ill patients: pros and cons
Indirect calorimetry: pros, (relative) cons and when adjustments are needed. Overview of benefits of indirect calorimetry technology, technical and clinical limitations, and situations when the measured resting energy expenditure should not be the target for total energy administration and adjustments are necessary. REE: resting energy expenditure, IC: indirect calorimetry, ECMO: extracorporeal membrane oxygenation, FiO2: fraction of inspired oxygen, PEEP: positive end-expiratory pressure, NIV: non-invasive ventilation, HFNO: high-flow nasal oxygen.
