Time-efficient EMI Risk Evaluation Method in a Hospital Environment

Abstract

Hospitals are one of the most critical and sensitive environments where possible EMI issue may have life-threatening effects. Although the electronic equipment placed within satisfies various EMC standards, a risk of EMI still exists. Due to the high complexity and dynamics of this system, the electromagnetic environment substantially differs from the one of an EMC laboratory. A full risk-based EMC analysis can significantly help mitigate this problem but requires plenty of effort, time, and careful management. In this paper, we present a simplified but robust, time efficient method of evaluating the electromagnetic risks, as an intermediate step before implementing a full risk-analysis campaign. Such an analysis allows to get the first impression about the environment and its influence on the medical device within.
