Exploring the utility of indirect calorimetry to optimise nutrition in paediatric intensive care (ICONIC-1): a prospective observational cohort study protocol

However, the feasibility of newer devices, such as the QNRG+ and the impact of IC-guided nutrition delivery on patient outcomes remains unclear.
