Indirect calorimetry: The 6 main issues

Background and aims Optimal nutritional therapy, including the individually adapted provision of energy, is associated with better clinical outcomes. Indirect calorimetry best tool to measure monitor energy expenditure hence optimize prescription. Similarly other medical techniques, indications contra-indications must be acknowledged optimise use indirect in routine. Measurements should repeated enable adaptation evolution, as may change substantially. This review at providing clinicians knowledge routinely interpret results. Method We performed a bibliographic research publications referenced PubMed using following terms: “indirect calorimetry”, “energy expenditure”, “resting “VCO2”, “VO2“, “nutritional therapy”. included mainly studies published last ten years, related principles, innovations, patient's benefits, practice medico-economic aspects. Results have gathered required for routine interpretation A few cases illustrate decision-making process around its application prescription, individual optimisation therapy. also describe latest technical innovations results tailoring nutrition therapy according measured benefits. Conclusion The encouraged strategy care.
