PURPOSE: To examine the validity of the ReeVue™ (RV) and CardioCoachCO2™ (CC) metabolic systems to measure oxygen consumption by comparison to a reference criterion, the MedicalGraphics CardiO2/CP™ (MG).

RESULTS: There were no statistical differences between the two MG tests. Therefore, MG VO2 values were averaged and compared to the RV and CC. No significant differences were found between the RV (202±45 mLO2/min), CC (209±51 mLO2/min), and MG (226±57 mLO2/min) systems.

CONCLUSIONS: These findings indicate that the ReeVue™ and CardioCoachCO2™ metabolic systems are comparable devices to the selected reference criterion for measuring oxygen consumption to assess resting energy expenditure.
