BACKGROUND & AIMS
Indirect calorimetry (IC) is the only way to measure in real time energy expenditure (EE) and to optimize nutrition support in acutely and chronically ill patients. Unfortunately, most of the commercially available indirect calorimeters are rather complex to use, expensive and poorly accurate and precise. Therefore, an innovative device (Q-NRG®, COSMED, Rome, Italy) that matches clinicians' needs has been developed as part of the multicenter ICALIC study supported by the two academic societies ESPEN and ESICM. The aim of this study was to evaluate the accuracy and intra- and inter-unit precision of this new device in canopy dilution mode in vitro and in spontaneously breathing adults.
METHODS
Accuracy and precision of oxygen consumption (VO
RESULTS
In vitro evaluation of the Q-NRG® accuracy showed measurement errors <1% for VO
CONCLUSION
Both in vitro and in vivo measurements of VO
