Photoplethysmographic characterization of vascular tone mediated changes in arterial pressure: an observational study

To determine whether a classification based on the contour of the photoplethysmography signal (PPGc) can detect changes in systolic arterial blood pressure (SAP) and vascular tone. Episodes of normotension (SAP 90–140 mmHg), hypertension (SAP > 140 mmHg) and hypotension (SAP  50% in a small PPG,...
