Energy expenditure appears highly variable among critically ill patients and in individual patients during various phases of illness. As a consequence, critically ill patients are at considerable risk of under- or overfeeding during ICU and post-ICU hospital stay, when rough and static estimates are used. The most recent international guidelines recommend regular indirect calorimetry to measure energy expenditure as a proxy for caloric requirement in ICU patients.

This review article summarizes current evidence supporting the role of higher protein intakes, especially during the early phases of nutrition therapy in acute illness, methods for assessing protein requirements, as well as, the currently available high-protein enteral and parenteral nutrition solutions. 

The study showed that VO2max is clearly elicited in all distances from the sprint to the marathon. A fast start and the time to reach VO2max is important in increasing VO2 kinetics and to improve exercise tolerance. The K5 portable breath-by-breath sampling system was used to measure VO2 and carry out the scientific study.

A new validation study on Cosmed Q-box system including both in-vitro and in-vivo testing was published on ERS (European Respiratory Society) Journal.

A new study was published on ERS (European Respiratory Society) Journal to provide LCI (Lung Clearance Index) reference values in pulmonary healthy adults.
