Electromagnetic interference to infusion pumps. Update2008 from GSM mobile phones

Abstract

Electromagnetic interference (EMI) to critical care medical devices has been reported by various groups. Previuos study demonstrated that infusion pumps are susceptible of false alarm buzzing and block of infusion, when exposed to various EMI sources. Aim of this paper is to investigate the changes in the risk of EMI from the estimates of our previous 2005 survey and to extend the EMI risk assessment to newer telecommunication products: DECT phones and WiFi terminals. With regards to GSM phones, compare to the results obtained in 2005, we observed a decrease in the rate of failure (from 58% to 30%). From our findings, the use of WiFi and DECT does not pose a real risk to infusion systems.

“…With the extensive use of mobile communication equipment, the electromagnetic interference (EMI) has become a serious threat to the function of electronic devices . Especially in hospital, the EMI on electronic devices threatens the life of patients . To protect sensitive devices from EMI, the traditional method is utilizing a full solid metal enclosure to shield sensitive devices .…”
