Abstract

Common pulse transit time (PTT)/pulse wave velocity (PWV) methods such as 2-site Photoplethysmography (PPG) can only provide a single type of waveform that lacks information diversity. In this study, we developed a dule-modal signal measurement system consisting of Impedance Plethysmography (IPG) and Multiwavelength Photo- plethysmography (MWPPG). The proposed IPG-MWPPG system was implemented and tested on wrist positions of normal human subjects. The preliminary results of this study showed that PTTs obtained between the peaks of IPG and corresponding MWPPG yielded PWV values within their physiological ranges reported previously. Thus, the IPG-MWPPG modality system could potentially be used for the unobtrusive monitoring of multiple physiological parameters including PWV, SpO2 and cuffless blood pressure in the future.
