Protegemed2: an extended platform based on RFID to identify EME and improve the detection of microshocks.

The use of electromedical equipment (EME) throughout the years has brought benefits in the aid of diagnosis and therapies as well as in surgical interventions. However, the equipment may fail and can cause health hazards, for example, the passing of a small but dangerous electric current through the patient (microshock). To prevent and minimize the risk of failure we propose the Protegemed2, an extension of the previous version called Protegemed, addressed in 2009. This system uses radio frequency identification to automatically identify EME and increases the performance of the system allowing a large-scale supervision of EMEs. Protegemed2 was built embedded into the gas and electric power panel of surgical rooms and uses an ARM 32-bit microcontroller.
