Remote Monitoring of Vital Signs in Chronic Heart Failure Patients

M.Arunkumar

The chronic heart failure (CHF) affects an ever-growing segment of population and it is among the major causes of hospitalization for elderly citizens. The actual out-of-hospital treatment model, based on periodic visits, has a low capability to detect signs of destabilization and leads to a high re-hospitalization rate. In this paper, a complete and integrated Information and Communication system is described to daily collect vital signs of the patients at home and automatically send them to the hospital database through GPS. This is achieved by using microcontroller along with a set of sensors which monitors the different vital signs of the patients. All signals are processed upon acquisition in order to assert if both punctual values and extracted trend lay in a safety zone established by thresholds. In case of emergency, the GPS module present in the kit will give a message or make a call to the physician and the caretaker of the patient to take necessary action. The vital signs are going to be monitored are electrocardiogram, blood pressure, temperature and spo2.
