From: VO2 and VCO2 variabilities through indirect calorimetry instrumentation
The VO2 and VCO2 variabilities definition. The variabilities are defined in terms of the MC and BbB techniques. The SDVO2 and SDVCO2 are for the mixing chamber (MC) and the vVO2[n], vVCO2[n] are for the breath by breath (BbB) techniques. The discrete gas exchange is defined at the mouth level as VO2[n] and VCO2[n] such that they include their own variabilities.
