Value

I have been dealing with aerobic power testing of athletes since the mid 1970’s, and have used a variety of equipment and protocols. In 2010 my work place decided to acquire a new metabolic analyzer. I looked through the available models and found in particular one interesting analyzer, the Moxus from AEI technologies. From projects I had done, I had experience with the S-3A oxygen and CD-3A CO2 analyzers, and knew they were extremely sturdy and long lasting, in addition to being very accurate. Their integration into a metabolic system made it possible to combine “on-line” measurements and Douglas bag measurements, making the system very suitable for both education and research. It was thus an easy decision to suggest Moxus as the new metabolic system.
Since then I have had ample opportunity to use the Moxus system in both research and more routine tasks. My experience is very good. The system is very stable, and has not needed any factory service. It performs well each time and requires little maintenance. In a study by Medbø, Mamen and Beltramo, Moxus was found to be a very accurate analyser (Medbø, Mamen, Beltramo, Appl. Physiol. Nutr. Metab. 37: 860–871 (2012). This has also been confirmed by Rosendahl et al., Eur J Appl Physiol 113: 1355-1367 (2013)..
In all, I have experienced the Moxus system to be highly valid and reliable, with little need for external service.
Frequently Asked Questions
1. Why is measurement accuracy important in metabolic cart testing?
Accurate VO2, VCO2, and RER measurements are essential for producing reliable research data, evaluating athletic performance, and making informed clinical decisions. High-precision metabolic carts help ensure consistent, repeatable results across multiple tests and subjects, reducing measurement variability.
2. What are the advantages of breath-by-breath gas analysis?
Breath-by-breath gas analysis provides real-time measurements of oxygen consumption, carbon dioxide production, and ventilation during exercise or metabolic testing. This allows researchers and clinicians to detect rapid physiological changes and obtain highly detailed respiratory data for accurate performance and clinical assessments.
3. Why do researchers choose AEI Technologies gas analyzers?
Researchers choose AEI Technologies because our S-3A Oxygen Analyzer and CD-3A Carbon Dioxide Analyzer deliver exceptional accuracy, fast response times, long-term stability, and repeatable results. These analyzers have been trusted in scientific research and clinical laboratories for more than five decades.
4. How do modular metabolic cart systems benefit laboratories?
Modular metabolic cart systems provide flexibility by allowing laboratories to customize their equipment based on specific research or clinical applications. As testing needs evolve, additional components and analyzers can often be integrated without replacing the entire system.
