Respiratory exchange ratio

Sunday, 20 March, 2022

The calorimetry components are operated as an open circuit measuring system for determining the parameters O2 consumption, CO2 production, respiratory exchange ratio (RER) and energy expenditure as well as difference O2 (reference air O2 - Box O2)and difference CO2 (Box CO2 - referenceair CO2). All these parameters may be calculated both offline and online by the TSE PhenoMaster software and can be displayed as required by the user.

Due to the different formula of the primary substrates used for metabolism, we can deduce from the respiration quotient the currently used metabolite and the nature of the metabolic processes.
