Key result
The Sensormedics S2900Z metabolic cart showed minimal bias for VO2 compared to the Douglas bag reference system during submaximal exercise in children, with greater variability for FeCO2 and VCO2.
Why the study?
Does the Sensormedics S2900Z metabolic cart accurately measure gas exchange compared to a Douglas bag in healthy children during exercise?
Population
10 active, healthy children, mean age 11.6 +/- 2.3 years.

Does the Sensormedics S2900Z metabolic cart accurately measure gas exchange compared to a Douglas bag in healthy children during exercise?
The Sensormedics S2900Z metabolic cart provides adequate VO2 measurements for pediatric exercise testing, despite some variability in CO2 metrics.
Unnithan et al. (1994) conducted a cross-sectional in Healthy children (n=10). Sensormedics S2900Z metabolic cart vs. Douglas bag was evaluated on Bias and variability for VO2, FeCO2, and VCO2. The Sensormedics S2900Z metabolic cart showed minimal bias for VO2 compared to the Douglas bag reference system during submaximal exercise in children, with greater variability for FeCO2 and VCO2.
