Does a novel computation of pulse transit time from multi-channel PPG signals correlate with reference blood pressure for non-invasive monitoring?
A novel system using ECG and dual-mode PPG sensors to compute pulse transit time shows strong correlation with reference blood pressure, suggesting feasibility for non-invasive blood pressure monitoring.
Being able to accurately monitor blood pressure in a reliable, truly non-invasive manner is a highly sought after goal within the biomedical community. In this paper we propose and assess a system, methodology and algorithm for unobtrusively obtaining true pulse transit time data from readily accessible peripheral locations, such as the hand, using a highly synchronous body-sensor-network encompassing an electrocardiogram- and dual mode photoplethysmogram sensor node. The results suggest the feasibility of acquiring such data, which strongly correlates with the recorded reference blood pressure, and can therefore be further employed to track changes thereof.
