Accuracy of Dexcom G6® and FreeStyle Libre® Sensors in Standardized Hypoxia Conditions: A Randomized Controlled Trial—FOX Study
Both CGM systems showed reduced accuracy under hypoxia, particularly during dynamic glycemic changes. Awareness of these limitations and selective confirmation with capillary testing can assist safe use when clinically relevant decisions are required. The implications for automated insulin delivery systems warrant further dedicated evaluation.
