“…Since immunity levels 2 and 3 are the most commonly applied levels to equipment projected to operate under hostile electromagnetic environments, it is not difficult to find a number of papers using 3 and 10 V/m as a reference limit [1][2][3][4][5][6][7][8][9].…”

“…Suppose that a given piece of equipment, in compliance with immunity Level 2 requirements, is operating within an environment whose critical frequency presents a 5 V/m wave-peak (e.g., 3.54 V/m maximum RMS ). This environment must be evaluated according to short-term EMI noise (peak detector) in order to verify the operating condition of this equipment.…”

“…As previously mentioned, a straightforward comparison of electromagnetic environment measurements and immunity levels for electroelectronic equipment has been used in the technical literature as a usual method to provide EMC management within critical areas [1][2][3][4][5][6][7][8][9]. However, it is possible to show that this approach may lead to wrong or overly conservative results.…”

“…For instance, a number of important papers regarding this scope can be listed here for hospital environment assessments [1][2][3][4][5][6][7][8][9]. Most of them usually compare environmental measurements with the immunity levels (3 or 10 V/m) prescribed for electromedical equipment according to IEC 60601-1-2 (EMC collateral standard).…”

Abstract-The straightforward comparison between electromagnetic environment measurements and immunity levels for industrial, scientific, and medical equipment has been used in the technical literature as an ordinary method to provide electromagnetic compatibility management within critical areas, such as hospital and industrial environments. This paper addresses a theoretical discussion concerning emission and immunity test features to focus the aforementioned problem. Finally, a more reliable comparison method is proposed, the environmental compatibility level definition, using analytical analysis and measurement results.

“…A partir da comprovação dessas interferências, a preocupação existente nos trabalhos mais recentes é quanto à restrição de áreas no hospital com relação ao uso de comunicadores móveis e ao estabelecimento de uma política para gerenciamento de EMI no ambiente hospitalar. Dois exemplos desses trabalhos são os trabalhos de Boyd et al (1999) e David et al (2000). Boyd mediu os campos elétricos em diversas áreas do Massachusetts General Hospital, sem a influência de radiocomunicadores para mapear apenas o ambiente eletromagnético do hospital.…”

Interferência eletromagnética (EMI) é a ocorrência de alterações funcionais em um determinado equipamento devido a sua exposição a campos eletromagnéticos. Os efeitos das EMIs são particularmente preocupantes quando ocorrem em equipamentos eletromédicos, sobretudo se estão monitorando ou dando suporte a vida de um paciente.Considerando que o aumento no número de fontes de radiofreqüências presentes no ambiente hospitalar, aumenta a probabilidade de ocorrência de EMI nos equipamentos eletromédicos, o objetivo desse trabalho é quantificar e classificar as alterações funcionais perceptíveis em determinados equipamentos eletromédicos quando expostos aos campos elétricos produzidos pelo telefone celular, operando nas potências média e máxima.Inicialmente foi realizada a medida da intensidade do campo elétrico produzido pelo telefone celular operando nas potências média e máxima, a diversas distâncias da antena de medida. Em seguida os equipamentos eletromédicos selecionados foram expostos aos campos elétricos medidos anteriormente.Os resultados das etapas experimentais permitiram observar um número significativo de alterações funcionais nos equipamentos eletromédicos testados, com graus variáveis de severidade.
