Does the Beckman Horizon MMC microprocessor-controlled exercise testing system accurately measure ventilation and gas exchange compared to standard methods?
The Beckman Horizon MMC microprocessor-controlled exercise testing system provides precise and accurate measurements of ventilation and gas exchange during exercise.
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.
