Multiple propane gas burns rate method to determine accuracy and linearity of indirect calorimetry systems: An experimental assessment of a method

This technical report aimed to assess the accuracy and linearity of three indirect calorimetry systems using our in-house built validation procedure. A series of trials at different propane burn rates (PBR) (i.e., 200, 300, 400, 500, and 600 mL/min) were run on three different indirect calorimetry systems. The experimental values for V̇O2 and V̇CO2 measured on the three IC systems were compared to theoretical stoichiometry values.
