The purpose of this methodology paper is to provide practical guidance to health professionals to perform this measurement safely, using various metabolic monitors. Indirect calorimetry is the best tool to assess resting energy expenditure in critically ill patients and ESPEN as well as ASPEN societies recommend its use. Nevertheless, the use of indirect calorimetry in the COVID-19 infection time...

A new paper on Clinical Nutrition focused on the decision-making process around IC application for prescription, and individual optimisation of nutritional therapy. Optimal nutritional therapy requires an individually adapted provision of energy as close as possible to patient's real energy expenditure (EE). Indirect calorimetry (IC) is the gold standard to measure EE and monitoring the variations...

The present guideline is an update and extension of the previous ESPEN guidelines on enteral nutrition (EN) and parenteral nutrition (PN) in adult critically ill patients published in 2006 and 2009, respectively. Since then, the ESPEN methodology has been upgraded resulting in rigorous evidence-based and consensus-based recommendations. The best and most updated knowledge from the literature, analysed...

A new key paper on Clinical Nutrition focused on the decisive role of Indirect calorimetry (IC) in clinical settings. IC has been long recognized as the gold standard for assessing basal or resting energy expenditure (REE) and determining energy requirement is a fundamental of nutrition support, particularly in the situation where adjustment of energy provision is critical. REE measurement does...
