Sensor network for extended health monitoring of hospital patients

Modern hospitals are equipped with a variety of medical devices for the care of the patients. A particular group of devices are the ones that monitor the patients´ vitals such as heart rate, oxygenation or blood pressure. Monitoring these vitals allows the doctors and nurses to respond quickly in case a patient´s condition is degrading and even to save his life. The disadvantages of such a system is that it is usually bulky, and patients who are wired cannot move away from the room. This paper proposes an efficient monitoring infrastructure for hospitals using compact and wireless devices that can be worn by every patient at all time, transmitting real-time data to a central place, which can be accessed by the doctors for expert diagnosis.
