Paper Abstract

The subject of this paper relates to the measurable effects of light behavior in biological materials. The modulations of biooptical signals, induced in tissues by arterial pulsations, are the basis of photoplethysmography (PPG), which by definition is an optoelectronic method for measuring and recording changes in volume of a body part. The PPG signal may be considered as the response of a given dynamic system to an input cyclical signal that is quasi-periodical. In the literature, the PPG attributes have been presented many times; however, the descriptions are mostly non-parametrical. On the contrary, a way of parametrical description using the methods that are utilized to identify dynamic systems is considered in this paper. A flow model and its mathematical description have been presented.
