Evaluation of a dual-PPG system for pulse transit time monitoring
Résumé
This work presents a new dual-photoplethysmographic (PPG) system for pulse transit time (PTT) monitoring. An experiment has been set up in order to compare the PTT measurement between carotid and radial arteries from two systems: our physiological multimodal platform (PMP) and the Complior® tonometer. This work explores the comparison between such optical and mechanical modalities. The results show that the PPG device tends to overestimate the PTT (RMSE = 16 ms). Furthermore, both mechanical and optical signals have been superposed and demonstrated that pulse morphologies are quite similar.
Clinical Relevance— A new device is presented, helping to find an alternative way for pulse wave velocity and blood pressure measurements than current techniques used.
