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.

Main findings

Compared with results from a 2005 survey, the observed rate of infusion pump failure with GSM phone exposure decreased from 58% to 30%. The authors report that WiFi and DECT use did not pose a real risk to infusion systems.

Outcomes measured

• Electromagnetic interference (EMI) to infusion pumps
• False alarm buzzing
• Block of infusion
• Rate of failure compared with 2005 survey

Limitations

• No sample size reported in abstract
• No exposure metrics (frequency, distance, power/SAR, duration) reported in abstract
• Methods and testing conditions not described in abstract
• Outcome definitions and statistical analysis not described in abstract

Suggested hubs

• school-wi-fi (0.2)
  Includes WiFi terminals as an exposure source, though in a medical device EMI context rather than schools.
• who-icnirp (0.1)
  General RF exposure/EMI topic; no explicit WHO/ICNIRP mention in abstract.
