Abstract

U ovom radu, postojećoj razvojnoj pločici dodana je funkcionalnost detekcije i mjerenja signala disanja metodom mjerenja impedancije prsišta i omogućen je prijenos, pohrana i prikaz tog signala zajedno sa signalom EKG-a na računalu. Napravljena je programska podrška za mikrokontroler i njegovu komunikaciju s analogno-digitalnim pretvornikom i računalom. Mjerni lanac je testiran kroz promjenu triju parametara u registrima analogno-digitalnog pretvornika. Osmišljen je i testiran algoritam za detekciju frekvencije disanja i izračun trajanja udisaja i izdisaja zasnovan na detekciji vršnih vrijednosti na mjerenjima provedenim na ispitaniku. Na kraju su prikazani i opisani artefakti uzrokovani pokretima ili refleksima poput govora, gutanja i hodanja.

Abstract (english)

In this paper, the functionality of the detection and measurement of the breathing signal by the chest impedance measurement function is added to the existing development board and the possibility to transfer, store and display is added to breathing signal along with the ECG signal on the computer. Programming support for microcontroller and its communication with an analog-to-digital converter and computer was made. The measuring chain is tested by changing three parameters in the registers of an analog-to-digital converter. An algorithm for breathing frequency detection and duration of inhale and exhale calculation based on detection of peak values were designed and tested on measurements conducted on the subject. Finally, artifacts caused by movements or reflexes such as speech, swallowing, and walking are showed and described.
