Q-NRG+ Metabolic Monitor
The indirect calorimeter designed by clinicians for clinicians. For critically ill patients who require nutritional support, Q-NRG+ offers quick and accurate resting energy expenditure (REE) measurement through indirect calorimetry (IC). International guidelines recommend use of indirect calorimetry to guide energy prescription to avoid under- and over- feeding.1,2
Energy requirements of critically ill patients are dynamic and vary by condition3
Predictive equations, while often used, are only accurate for up to 50% of critically ill patients and can lead to under- or over- feeding.4 Energy deficits are associated with increased mortality and morbidity including increased length of hospital stay, infections and prolonged mechanical ventilation.5-8 Whereas overnutrition is associated with increased hyperglycemia, hepatic steatosis, and mortality.8,9 Optimizing nutrition support may be difficult with the lack of insight into the variable energy needs of ICU patients.3
“The accuracy of predictive equations is very low.
And this could lead to overfeeding or underfeeding
the patient leading to increased mortality or morbidity.”Dr. Pierre Singer

Use of the gold standard, indirect calorimetry (IC), to measure caloric needs may improve outcomes1,10-12
Accurate assessment of nutritional requirements for critically ill patients is at the core of nutritional support. In a 2021 metaanalysis, Duan et al. showed that IC-guided nutrition therapy significantly reduced short-term mortality.11 Reaching energy targets guided by IC and provision of supplemental parenteral nutrition (SPN) demonstrated a reduction in hospital infection rates greater than 25%.5 Additionally, randomized control trials using SPN to cover energy needs measured by IC showed improvement in immunity or less systemic inflammation.13

IMPORTANT SAFETY INFORMATION
Q-NRG+ Indications for Use: This device is intended for the measurement of REE for spontaneously breathing and ventilated patients, with some limitations in accordance with labeling, within the following population: spontaneously breathing subjects >15 Kg (33 lb), when tested with the Canopy dilution technique, ventilated subjects >age 10 and >10 Kg (22 lb), and spontaneously breathing subjects > age 6 and >10 Kg (22 lb), when tested with Face Mask. This device is not suitable for operating in presence of flammable anesthetic gases or gases other than O2, CO2, N2 and water vapor. The device is to be used by physicians or by trained personnel under the responsibility of a physician. The device is not intended as a continuous monitoring device for surveillance of vital physiological processes.
Warnings: This device measures clinical parameters used to aid diagnosis and it is intended only as an adjunct device in patient assessment. In case of disturbing conditions, the shutdown is allowed because the safety of the device towards patients and operatorsis not affected, since the final evaluation is performed on the outcome data measured during a complete test. No modification of thisdevice is allowed.
For the safe and proper use of the devices mentioned herein refer to the User Manual.
