Implication

Validation study demonstrates accurate simulation of respiratory gas exchange for metabolic analyzers, indicating dependable calibration across variable ventilation rates.

Key Points

To develop an automated simulator of respiratory gas exchange for on-line calibration of metabolic measurement systems independent of minute ventilation.
Constructed a pump system that intakes ambient air and blends it with a certified calibration gas mixture containing 21% CO2 and 79% N2.
Engineered the simulator to expel gases using flow waveforms and concentration profiles that emulate normal human expiration while decoupling metabolic rate from ventilatory rate.
The simulator reproduced oxygen uptake and carbon dioxide output across a physiological performance range of 0.2 to 5.0 l·min⁻¹.
The system achieved simulation of respiratory and metabolic parameters with an accuracy of ±2%.
