IMPLEMENTATION OF PULSE OXIMETER FOR MEASUREMENTS IN UNCONTROLLED CONDITIONS

V diplomskem delu predstavimo izvedbo pulznega oksimetra, ki je bil zasnovan za meritve v nenadzorovanih razmerah, kar običajnim oksimetrom predstavlja veliko težavo. Glavna sprememba je bila v uporabi linijskega senzorja s poljem 102 fotodiod. V delu smo uspešno načrtovali in izdelali elektronsko vezje, prav tako smo izdelali programsko opremo za uporabljen mikrokrmilnik. Rezultate meritev, ki jih pošiljamo na osebni računalnik preko vodila USB, primerjamo z referenčno napravo EKG.In this thesis we introduce implementation of pulse oximeter designed for measurements in uncontrolled situations which greatly affect the performance of classic oximeters. Major improvement was applied by using the line sensor - array of 102 photodiodes. In the presented work we have successfully designed and produced electronic circuit and implemented software for the used microcontroller. The results of measurements are sent to a personal computer through USB bus and are compared to a reference ECG signal
