Text
Masked Breaths in last 120s
New in R8. Breaths in last 120s of REE measurement masked during QC process. Includes mistriggers; and breaths which are physiologically implausible; non-representative or unstable.
Integer
AtmosphericPressure
New in R8. Mean atmospheric pressure during REE measurement as assessed by Jaeger device. Millibars.
Millibars
Integer
AmbientTemperature
New in R8. Mean ambient temperature during REE measurement as assessed by Jaeger device. Degrees Celcius.
Celcius
Integer
OK Breaths in last 120s
New in R8. Breaths in last 120s of REE measurement remaining after QC process. Includes valid; stable breaths representative of underlying metabolism. These breaths are used to calculate mean VO2; VCO2; REE and RER
Integer
Proportion OK Breaths in last 120s
New in R8. Proportion of total breaths in last 120s of REE measurement remaining after QC process. = ree_ok_breaths_last120s / (ree_ok_breaths_last120s + ree_masked_breaths_last120s)
Percent
Real
Resting Energy Expenditure
New in R8. Resting energy expenditure derived using mean VO2 and VCO2 over last 120s. Calculated using Abbreviated Weir Formula; REE = 1.44(3.9VO2 + 1.1VCO2). Kcal/day
kcal/day
Real
Respiratory Exchange Ratio
New in R8. Respiratory Exchange Ratio derived using mean VO2 and VCO2 over last 120s. RER = VCO2 / VO2. Ratio

Integer
Mean VCO2 over last 120s
New in R8. Mean VCO2 (CO2 production) over last 120s of REE measurement based on breaths passing QC process. Derived by breath by Jaeger device and averaged over OK breaths in last 120s. mL/kg/min
