New theory enables cuffless blood pressure estimation via smartphone camera

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new mathematical framework called Attractor-Vascular Coupling Theory (AVCT) to estimate blood pressure using smartphone photoplethysmography (PPG). This theory posits that cardiac attractor geometry contains sufficient information for accurate blood pressure readings. A model trained on AVCT-derived features achieved very low mean absolute errors for systolic and diastolic blood pressure, meeting stringent AAMI standards and demonstrating the potential for clinical-grade BP tracking with just a smartphone camera.

IMPACT Enables non-invasive, clinical-grade blood pressure monitoring using readily available smartphone technology.

    Attractor-Vascular Coupling Theory: Formal Grounding and Empirical Validation for AAMI-Standard Cuffless Blood Pressure Estimation from Smartphone Photoplethysmography

    This work proposes Attractor-Vascular Coupling Theory (AVCT), a mathematical framework showing that cardiac attractor geometry encodes blood pressure (BP) information sufficient for AAMI-standard estimation, and validates the theory through a calibrated cuffless BP model using ph…
