R3HMS, An IoT Based Approach for Patient Health Monitoring

Present tradition of Internet of Things (IoT) employed in healthcare services are not suitable in developing countries like Bangladesh due to the complexity, technical difficulty in maintenance and astronomical price tag. In order to fill this gap, this paper presents R

HMS(Remote Reliable and Real-time Health Monitoring System), an approach a to low cost, easy to maintain and easy to install IoT-based health monitoring system for 24 hours continuous screening of patients which can be employed in both large hospitals in urban area as well as in resource limited hospitals in rural areas. The system measures patients physiological signals like ECG, respiratory airflow and SpO2 and sends these extracted data to a remote server. ESP8266 Wi-Fi chip is chosen for wireless communication and an 8-bit MCU ATmega328p is used to accumulate and process data to reduce load on the ESP8266. With the help of Amazon Web Services(AWS)data is securely transferred between devices using MQTT messaging protocol. These data can be viewed and analyzed by specialists, doctors and other paramedical staffs in real-time to monitor patient's state.
