Abstract

The subject of this paper relates to the measurable effects of light behavior in biological materials. Contribution is focused on problems connected with noninvasive evaluation of the arterial blood oxygenation using pulse oximetry. Its concept allows extending areas of application, exceeding over the continuous defection of changes in oxygenation of blood in arterial peripheral vessels. Some examples of such modern applications are discussed. Taking into account advantages of the transmission variant of the method, problems with its modified use in analysis of biooptical signals acquired from the living tissues are considered. The author cites two kinds of her studies, which are based on such analysis: evaluation of specific parameters of photoplethysmograms, and modeling of effects of light-tissue interaction.
