Q-NRG

The Next Generation of Metabolic Monitors for Indirect Calorimetry in Clinical Practice

OVERVIEW

The Q-NRG is the first indirect calorimeter specifically designed for measuring resting energy expenditure (REE) in spontaneously breathing subjects.

Indirect calorimetry enables an individualized measurement of metabolism, rather than estimates derived from predictive equations.

Developed in collaboration with COSMED and leading international nutrition institutes, Q-NRG’s product concept and technical specifications were defined alongside the ICALIC Trial study group to ensure clinical relevance and methodological rigor.

This collaboration resulted in a metabolic system that delivers high accuracy while remaining simple to use in clinical practice.

Q-NRG is a medical device.

KEY FEATURES

Individual assessment

The Q-NRG uses indirect calorimetry to assess metabolism through direct measurement of gas exchange. Results accurately reflect an individual’s metabolic status, supporting evaluation of fitness, response to nutrition strategies, and weight management planning.

Gold Standard

With more than 30 years of experience behind its design, Q-NRG has been validated in vitro and in vivo in international multicenter studies.

Quick to operate, clean
and maintain

Q-NRG is designed to minimize setup and measurement time. The system requires minimal warm-up and no daily user-assisted calibrations, with all functions performed through a few taps on the touchscreen.

Easy workflow

An intuitive interface and guided prompts make the Q-NRG simple to operate across all procedures, reducing setup time and user error.

Compact

The Q-NRG is a lightweight, portable system that runs on battery or can be plugged in, without sacrificing the comfort of a large LCD color touchscreen.

Affordable

Q-NRG has been designed to compete with conventional metabolic systems, at a fraction of the cost.

PRODUCT INSIGHT

Q-NRG provides flexibility across a wide range of clinical settings, enabling metabolic assessment in diverse patient populations from pediatrics (≥10 kg) to adults using either a canopy hood or optional face-mask testing.
