Quark RMR

The gold standard for metabolic measurement in applied human physiology research

  • The Quark RMR is a state-of-the-art metabolic system 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.

    Quark RMR is a medical device.

    Quark RMR
  • Key Features
    Unsurpassed reliability. Fast-response stable and durable paramagnetic technology for O2 sensor, and rapid infrared for the CO2. Both analyzers can ensure reliable data for a long time without requiring their replacement.

    Breath by Breath & Mixing Chamber. Quark RMR is provided with Breath by Breath analyzers however the system is also available with an optional Mixing Chamber.

    Modular architecture allows to configure Quark RMR according to the different metabolic testing requirements. This cost-effective solution gives the opportunity to scale at any time to a more complex configuration.

    Low running costs and easy maintenance. Quark RMR design has been conceived to reduce ordinary maintenance and to easily and rapidly solve any possible technical problem through parts replacement.

    Powered by OMNIA software innovative user interface, touch screen ready, easy-to-use and self-explanatory.

    Calibrations and Verifications procedures are available to ensure that main measurement components perform according to their specifications.

    Independently validated technology. Quark RMR is the only metabolic cart in the market that has been validated both on different gas exchange methods (Breath by Breath and Mixing Chamber), and on the whole human physiological range (from resting to a wide range of exercise intensities).
