Can a wearable glucose sensor be trusted in the ICU? new study aims to find out

This study is checking how accurate the Dexcom G7 continuous glucose monitor is for patients in the intensive care unit after major abdominal surgery or organ transplant. Researchers will place two sensors on each patient—one that is calibrated and used to guide insulin dosing, and one that is not calibrated and kept hidden. By comparing the readings from both sensors to standard blood glucose measurements, they hope to determine whether the device can reliably detect dangerous highs and lows in blood sugar in critically ill patients.
