Implementação de um sistema de aquisição e processamento de sinais de oximetria com comunicação bluetooth e software de monitoramento

Abstract

The present work introduces a study and implementation of a data acquisition and data processing system of oximetry signals from a pulse oximeter. This device provides information about the percentage of arterial oxygen saturation, heartbeat per minute and the plethysmograph curve. The system also includes data transmission to a mobile device using Bluetooth as the communication protocol. This work approaches oximetry concepts, the project of a hardware model using the integrated circuit AFE4490 with the Bluetooth module HC06 and also, the development of the Arduino code; the Android application and the Matlab software used for visualize data. The analysis of the results demonstrates a satisfactory system operation, since the values of the acquired data are close to the values obtained from a commercially used oximetry.
