Wristband AI Predicts COPD Flare-Ups 4 Days Early With 85% Accuracy

COPD exacerbations cause irreversible lung function decline, hospitalization, and death; early detection via this system could prevent severe episodes and reduce patient disability.

For millions living with chronic obstructive pulmonary disease, the danger has always arrived without warning — a sudden flare-up that steals lung function and, sometimes, life itself. Researchers in France have now developed a quiet, wrist-worn device called BVS3 that reads the body's subtle signals and, with 84.8 percent accuracy, foretells these crises an average of four and a half days before they unfold. The system asks almost nothing of the patient — only that they wear it — and in doing so, it proposes a quiet revolution: that medicine need not always wait for suffering to begin before
