Quark RMR (Resting metabolic rate)
The Quark RMR is a state-of-the-art metabolic cart designed for accurate measurement of Resting Energy Expenditure (REE) and respiratory ratio (R), in a non-invasive way, through the measurement of oxygen consumption (VO2) and carbon dioxide production (VCO2) together with other ventilatory parameters. Energy requirements are monitored accurately and instantaneously either on spontaneously breathing subjects with a flow-dilution canopy hood or (optionally) to mechanically-assisted patients by inserting directly at the patient’s circuit a disposable flowmeter (Flow-REE). The number of available configurations make the Quark RMR the most versatile metabolic cart for applied research in human physiology. Quark RMR’s accuracy and reliability have been validated against Gold Standard methods either with spontaneously breathing subjects (at rest and during exercise) and mechanically assisted patients.
