New theory offers cuffless blood pressure estimation from smartphone PPG

Researchers have developed the Attractor-Vascular Coupling Theory (AVCT), a new framework for estimating blood pressure using smartphone photoplethysmography (PPG). This theory-guided approach connects vascular dynamics with PPG signal analysis to derive interpretable blood pressure predictors. Empirical validation using a LightGBM model on two datasets showed promising results, with mean absolute errors for systolic and diastolic blood pressure falling within commonly cited thresholds for AAMI/ISO and BHS criteria, though not establishing full compliance with device-validation standards. AI

IMPACT This research could lead to more accessible and convenient blood pressure monitoring using everyday smartphone technology.
