MEDiSN: Medical Emergency Detection in Sensor Networks

Outline:

The increasing aging population size, nursing staff shortages, and decreasing hospital capacities suggest that the current level of care may decrease in the future. Furthermore, lack of resources and communication infrastructure can also prevent first responders from saving lives in disaster response scenarios. In response to these challenges, we have assembled an interdisciplinary team of researchers and practitioners to develop a Wireless Sensor Network (WSN) with the goal to automate the process of patient monitoring.

As shown in the figure, MEDiSN consists of Patient Monitors (PMs), Relay Points (RPs) and a Doctor Station. The PMs (MiTags) are custom made with a Sentilla Tmote Mini as its processing core and a Nellcore PulseOx board as the sensing unit. It is used to collect and secure the patients' vital signs and pass over the information to the wireless mesh infrastructure of RPs. RPs relay packets to the Doctor Station via a tree protocol to sent over the internet to the central server.

The system has been deployed at the operating room and post anesthesia care unit of the Shock Trauma Center of the University of Maryland Medical Center and currently deployments are being done at the emergency rooms of the Johns Hopkins Hospital and the Washington Hospital Center. Test results show that our system can easily adopt to real hospital environments with good performance.
