Refining healthcare monitoring system using wireless sensor networks based on key design parameters

Abstract

Wireless Sensor Network (WSN) can be effectively used for continuous monitoring of patient in hospitals and in homes for elderly and baby care. Proposed system is a smart healthcare monitoring system using WSN which can monitor patients admitted in the hospital continuously without any interference of wires around patient bed. We are accentuating the advantage of wireless sensor network over wired system by attaching various advanced sensors to this network to collect various body parameters of a patient such as blood pressure, temperature, heart rate, pulse rate and blood oxygen level (SPO2) wirelessly. A kind of WSN called as WBAN is used for this purpose. Many designing requirements like flexibility, miniaturization, portability, non-intrusiveness, and low cost are studied and considered to the make system more efficient. Different available wireless standards are compared for the intermediate communication based on various parameters. Proposed system is a Healthcare Monitoring System with ESP8266 NodeMcu WiFi wireless communication using Arduino Nano boards. This system can detect the abnormal health conditions of patients, issue an alarm in emergency conditions and send SMS/E-mail to the physician, caregiver and relatives of patient.
