Cuffless Blood Pressure Estimation From Wearable Photoplethysmography and Windkessel Model-Regularized Learning Approach
Adeeba Khan, Swarubini P J, Ryunosuke Kirita, Tomohiko Igasaki, Nagarajan Ganapathy (IIT Hyderabad, Kumamoto University)
Summary
Adds a bounded Windkessel loss: arterial pressure must decay exponentially with a PPG-derived diastolic time constant. 10 healthy subjects, wearable finger PPG, rest + affective stimulation + Stroop. MAE SBP 4.10 ± 1.41, DBP 2.90 ± 1.20 mmHg; authors claim AAMI compliance (n = 10 can't meet AAMI's 85-subject requirement).
