CHF PATIENT MONITORING USING MSP430 CONTROLLER AND WIRELESS SENSORS

Abstract

Chronic heart failure (CHF) is a major cause of hospitalization in elderly people. Millions of people in industrialized countries like Europe and U.S are affected by this chronic disease. Wireless Sensor Network enables to monitor alterations in patient’s physical parameters for detection of chronic disease in early stage. Set of wireless sensors with microcontroller send health status data to home server via low power ZigBee communication protocol. Home server is responsible for the sensor data acquisition and signal processing. For different parameters like temperature, ECG, pulse oxymetry, blood pressure threshold levels are set and compared with monitored parametric values. Processed data is transferred to remote healthcare system using General Packet Radio Service (GPRS). Critical situations can be identified and alert message can be forwarded to medical staff/caretaker & accordingly necessary action can be taken. Wireless communication helps to speed up the process of detecting destabilization signs. Proposed system provide many benefits like reduction in lengthy stays in hospital, avoid frequent visits to hospitals for regular checkup, reduction in medical staff’s workload. Home based healthcare system is introduced which is convenient for patient as well as the physician.
