Key result
The Beckman Horizon MMC exercise-testing system demonstrated high precision for measuring VO2 (r=0.991) and VCO2 (r=0.993) during steady-state exercise.
Why the study?
Does the Beckman Horizon MMC microprocessor-controlled exercise testing system accurately measure ventilation and gas exchange compared to standard methods?
Observational (n=115)

N. L. Jones (1984) conducted an observational in Healthy subjects and patients with cardiorespiratory disorders (n=115). Beckman Horizon MMC exercise-testing system vs. Breath-by-breath analysis system was evaluated on Precision and agreement of measurements of ventilation (VE), VO2, and VCO2. The Beckman Horizon MMC exercise-testing system demonstrated high precision for measuring VO2 (r=0.991) and VCO2 (r=0.993) during steady-state exercise.
