Q-NRG is the first Indirect Calorimeter specifically intended for Resting Energy Expenditure (REE) measurement on spontaneously breathing subjects.
Indirect calorimetry provides an individual and dynamic metabolic assessment based on the actual physical status of the subject rather than estimating it on anthropometric data.
Q-NRG is the result of COSMED’s collaboration with world-class institutes in the field of nutrition. Product concept and specifications have been designed together with the ICALIC Trial study group.
This collaboration made possible the development of an accurate metabolic system simple to use.
