RESUMO

Electromagnetic interference (EMI) is a degradation on the performance of an equipment, due to an electromagnetic disturbance, as consequence of the coupling of electromagnetic energy between an equipment "source" and an equipment "victim". This coupling occurs by radiation or conduction. This work aims to test main monitoring and life-supporting medical equipment currently used at operating rooms and ICTUs (Intensive Care Units) of some hospitals, based on the effective standards of electromagnetic compatibility, and to present qualitative and quantitative results, revealing the effect of the conducted electromagnetic interferences in these equipment. The results confirmed the occurrence of EMI events that may represent an additional risk condition to the patient, and demonstrated that imported and new equipment (<2 years), stimulated by the requirements of certification and standardization, have better performance in hostile electromagnetic environments.
