Code
Oxymax Economy

Oxymax Economy VO2, VCO2, RER, Heat

The Columbus Instruments Oxymax Eco System is an indirect open circuit calorimeter designed to measure the metabolic performance of a single subject. The system monitors oxygen and carbon dioxide concentrations by volume at the inlet and outlet ports of a chamber, canopy, tent, or mask through which a known flow of air is being forcibly ventilated. The difference in gas concentrations along with flow information is employed to calculate oxygen consumption, carbon dioxide production, respiratory exchange ratio and heat. All data provided by the Oxymax Eco is corrected to an STP of 0 and 760 mmHg. The system presents data in normalized forms that are user-defined.

The Oxymax Eco can be configured for positive or negative ventilation of a single subject. Flows between 100 mL/Min and 15,000 LPM are supported. The instrument supports all of the facilities of the Oxymax Equal Flow System with the limitation of working with only a single subject. The Oxymax Eco can be upgraded to support multiple subjects and provides a low cost entry into calorimetric measurements while providing the possibility of adding features to meet increasing demand.
