Summary

Gas exchange measurement systems are complex and require specialized facilities and expertise. As a result, access to these measurements remains limited, particularly in the field of sports performance. The aim of this validation study was to compare measurements obtained with a reference device and a new portable system.

DEVICE

ZoneX

The ZoneX device was developed by PAIRFS. It is a system designed to measure changes in expired volume and fluctuations in the fractional concentration of carbon dioxide in exhaled air (FeCO₂) in healthy volunteers. These data are transmitted in real time via Bluetooth Low Energy (BLE) to dedicated PC software for acquisition and analysis. The device is CE-marked, demonstrating compliance with applicable European regulatory requirements (certificate of conformity provided in the appendix).
