This article discusses the use of photoplethismographic method for the analysis of inflammatory processes. The aim is to show the effectiveness of using of photoplethismographic method in the analysis of the microcirculation level of peripheral vascular in inflammatory processes. As a result of researches that carried out at the Department of Maxillofacial Surgery of the Vinnitsa National Medical University, it was examined 30 patients (21 men and 9 women aged 20 to 60 years) with odontogenic abscesses and phlegmon. Treatment of patients included removal of the causative tooth, opening cellulitis or abscess, ozone therapy with silver ions. Application of this method allows dentists accurately determine: the effectiveness of the treatment; specify the duration of the rehabilitation period; identify various vascular disorders in fractures of the jaw; to evaluate the effectiveness of local anesthesia; to apply this method to plastic surgery and transplantation.

This paper presents firstly-engineered photoplethysmographic multispectral device for diagnosis the peripheral blood circulation. The calculation of the main errors as: primary converter error, methodical error of measurement, setting of optical-electronic sensor error was carried out. Moreover the assessment of reliability of diagnosis the engineered device was conducted. Streszczenie. Artykuł prezentuje pierwsze rozwiązanie wielospektralnego urządzenia fotopletyzmograficzego do diagnostyki obwodowego przepływu krwi. Przeprowadzono obliczenia głównych błędów: podstawowego błędu przetwarzania, błędu metodyki pomiaru, ustalonego błędu przetwornika optoelektronicznego. Ponadto przeprowadzono ocenę niezawodności zaprojektowanego urządzenia. (Kalibracja metrologicznych charakterystyk wielospektralnego urządzenia fotopletyzmograficznego do diagnostyki obwodowego przepływu krwi).
