Our new preprint about PulseOx-FM: a foundation model trained on ~7M overnight pulse-ox segments from >10,000 Human Phenotype Project participants
We show that a wearable sleep signal carries broader physiology than standard HR, SpO₂, or apnea features
PulseOx-FM beat engineered PPG and proprietary feature sets on age prediction, generalized to an external surgical cohort, and performed well across 64 phenotypic cardiometabolic, sleep, imaging, medication & neuropsychiatric targets
It also captured 2-year hypertension incidence from baseline, and next-day glycemic, dietary & activity state within individuals
