Summary:
The photoplethysmography is one of the widely used techniques in medical settings and sports equipment to measure biological signals produced by cardiovascular system (CVS). It is recognized that the photoplethysmogram (PPG), which can be defined as the continuous recording of the light intensity scattered from a given source by the tissues and collected by a suitable photodetector, can provide valuable information about CVS performance, however, PPG dynamics is not yet fully understood [1]. This study sought to investigate properties of local (in chosen region on reconstructed trajectory) and global (overall trajectory) short-term prediction performance of the PPG. The results demonstrated certain similarities between global prediction performance of the PPG and noise induced Duffing's forced oscillator; and that local and global predictability may differ considerably, that may explain fluctuations observed in the global prediction performance and give insight into local properties of the PPG.
