Колебания объемного кровотока, характеризуемые фотоплетизмограммой, рассматриваются как источник температурных волн различных частот, одновременно распространяющихся в биоткани и являющихся основной причиной колебаний температуры кожи. Группу испытуемых составили 10 человек в возрасте 20-35 лет, без установленных сердечно-сосудистых отклонений. С помощью вейвлет-анализа для каждого испытуемого были исследованы отдельные спектральные составляющие сигнала фотоплетизмограммы и колебаний температуры кожи. В результате построены частотные зависимости задержки и затухания спектральных составляющих температурного сигнала относительно составляющих сигнала фотоплетизмограммы в эндотелиальном (0,005-0,02 Гц) и нейрогенном (0,02-0,05 Гц) диапазонах. Использованная аппроксимация полученных частотных зависимостей позволяет перейти от температурного сигнала к сигналу фотоплетизмограммы с помощью временного сдвига и компенсации затухания спектральных составляющих колебаний температуры. Установленная связь температурного сигнала с сигналом фотоплетизмограммы в области пальцев может служить основой для применения термометрии в качестве способа мониторинга медленных колебаний периферического кровотока.</p></abstract><trans-abstract xml:lang="en"><p>Possibilities of the restoration of photoplethysmography signal through the finger tips temperature measurements have been investigated. Blood flow oscillations, characterized by photoplethysmogram, are considered as a source of temperature waves of different frequencies, simultaneously propagates in a biotissue and are the main reason of the skin temperature oscillations. Research subjects were 10 man of 20-35 years without any case of cardiovascular diseases. By means of wavelet analysis for each subject individual spectral components of the photoplethysmogram and oscillations in skin temperature were investigated. As a result the frequency characteristic of delay and attenuation of the spectral components of the temperature signal in relation of the photoplethysmogram components in the endothelial (0.005-0.02 Hz) and neurogenic (0.02-0.05 Hz) ranges have been plotted. Use of the approximation of the frequency dependencies allows us to get photoplethysmogram by means of time shift and attenuation compensation of spectral components of the temperature oscillations. Established interrelation of the temperature signal with the photoplethysmogram in the finger tip area can serve as a basis for the application of thermometry as a method of monitoring of slow oscillations of peripheral blood flow.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>колебания температуры</kwd><kwd>колебания кровотока</kwd><kwd>термография</kwd><kwd>фотоплетизмография</kwd><kwd>свойства кожи</kwd><kwd>вейвлет-анализ</kwd><kwd>температурная волна</kwd><kwd>temperature oscillations</kwd><kwd>blood flow oscillations</kwd><kwd>thermography</kwd><kwd>photoplethysmography</kwd><kwd>skin properties</kwd><kwd>wavelet analysis</kwd><kwd>temperature wave</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Березовский В.
