Analyzing gas exchange – VO₂, VCO₂, ventilation – is now the gold standard for understanding exercise physiology, determining ventilatory thresholds, and personalizing training. However, the market offers highly contrasting technological approaches: on the one hand, cumbersome, complex, expensive, but extremely precise systems; on the other, much more affordable and simpler devices, but with limited accuracy. This article discusses data quality, trade-offs, and why PAIRFS decided to invest in...

ZoneX analyzes respiration and it is important that it is used correctly to provide reliable and high-quality information. The following video explains how to do this: Steps to attach ZoneX to the mask Here are the logical steps to mount ZoneX onto the respirator mask, as illustrated in the video: Insert the internal breathing tube into the mask — this tube acts as a conduit between your mouth (or airway) and the ZoneX sensor. It ensures that inhaled/exhaled air passes into the measurement...
