Introduced by COSMED, world-wide leader in the design of metabolic systems for clinical and human performance applications, Q-NRG is the first Indirect Calorimeter specifically intended for the measurement of Resting Energy Expenditure (REE) in patients who are mechanically ventilated or spontaneously breathing and for healthy subjects.
Q-NRG is a unique product, resulting from the COSMED’s collaboration with world-class institutes in the field of nutrition support in intensive care units¹. This collaboration has made possible the development of an accurate metabolic system easy to use and at the same time resolving all typical pitfalls of the indirect calorimetry technology (no warm-up time, no gas calibrations, etc.).
Q-NRG is the ultimate tool to understand how to support a patient according to his/her real energy requirements, to help improve glycemic control, reduce length of stay and, ultimately, decreasing costs of the Intensive Care Unit.

A new industry standard
Q-NRG has been developed in close collaboration with world-class institutes in the field of nutrition support in ICU. Product concept and specifications have been designed together with the ICALIC Trial study group.
Gold Standard Measurements
Q-NRG is the result of more than 30 years of experience in the design of metabolic systems. The new calorimeter has been validated in-vitro and in-vivo to achieve the greatest accuracy, with excellent agreement vs. mass spectrometer measurements (link).
Optimized user experience
Q-NRG has been designed to minimize operations and time to measurement. System does not require warm-up time nor user-assisted calibrations. The usability of the device has been designed according to best clinical practices.
ONE tool for many applications
Q-NRG provides all the flexibility in a variety of clinical settings, assessing different patient’s conditions (mechanically ventilated or spontaneously breathing) and with different techniques (Canopy Hood and/or face masks), from pediatric (age 6) to adult.
designed for icu
Cleaning procedures are simplified thanks to the product’s design with all surfaces having rounded shapes. The internal breathing circuit is made to avoid that exhaled breath contaminates internal parts. Cross-contamination prevented with single-use disposables and antibacterial filters.
latest technology in a compact design
Q-NRG is a compact, lightweight, battery operating device. The 10.1” inches LCD touchscreen simplify access to all operations. Bluetooth, USB, RS-232 and LAN interfaces to connect the system to any hub (PC, printers, etc.).
Assess Energy Requirements in mechanically ventilated patients (up to 70% of FiO2). Using disposable flowmeter and sampling lines to exclude any possible patient contamination.
Measure REE on spontaneously breathing subjects by Dilution technique by means of a Canopy Hood (available in Adult and Pediatric sizes).
The optional Face Mask Kit available for both Q-NRG models includes an external flowmeter and 2 oro-nasal face masks (Small, Medium Size) to measure REE without the need of a Canopy Hood. Masks are available in 5 sizes

Hospital Malnutrition is a negative prognostic factor in ICU. Most patients are underfed and nutritional targets are rarely reached¹. Increased energy intake is associated with improved clinical outcomes in critically ill patients².
Energy Expenditure (EE) in ICU patients is highly variable depending on the severity of the disease and treatments. Clinicians need to measure EE by indirect calorimetry (IC) to optimize nutritional support to reduce number of complications, particularly infections³. However, until now indirect calorimeters available on the market have had insufficient accuracy for clinical and research use. Difficulties of handling and interpretation of results limited IC in ICU patients. An accurate, easy-to-use calorimeter has been developed to meet these needs.

The introduction of an Optimal Energy Provision regime through indirect calorimetry is widely recognized to have a strong impact on patient's length of stay (LOS) and, consequentially, on the overall costs in ICU. Visit our on-line calculator to understand how introducing Indirect Calorimetry Technology in your ICU department may impact your cost savings.
Note: Calculations are based on published scientific evidence on reduced LOS and costs savings associated with individual nutrition support based on measured Resting Energy Expenditure.
