Key result
A computerized metabolic system accurately measured gas exchange compared to the Douglas bag method, with extremely small differences (e.g., VO2 difference of -0.018 l/min).

Does a computerized metabolic system using inspiratory and expiratory methods accurately measure gas exchange compared to the Douglas bag method in male subjects?
A computerized metabolic system using inspiratory or expiratory configurations provides highly precise gas exchange measurements comparable to the Douglas bag technique but in less time.
Bassett et al. (2001) reported a cross-sectional. Computerized metabolic system vs. Douglas bag method was evaluated on Gas exchange variables including FE(O2), FE(CO2), and VO2. A computerized metabolic system accurately measured gas exchange compared to the Douglas bag method, with extremely small differences (e.g., VO2 difference of -0.018 l/min).
