A Preliminary Study for Unconstrained Pulse Arrival Time (PAT) Measurement on a Chair.
A method of measuring the pulse arrival time (PAT) non-consciously on a chair is proposed. In this method, the electrically non-contact ECG measurement system and the air cushion with balancing tubes are used. In this paper, the correlation between the typical PAT and the unconstrained PATs (A-PATs) are compared. The typical PAT is measured as the difference of R-peak of ECG and the steepest descent point of the PPG in toe. The three different A-PATs were measured from the pressure pulse of the air cushion (APP). The correlation between the typical PAT and the A-PAT from the steepest descent point of the APP was the highest (R=0.9663).
