“…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].…”

“…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 de la comprobación de las interferencias en los equipos médicos, la preocupación existente en los trabajos siguientes se centró en identificar la influencia de fuentes externas al hospital, principalmente las relacionadas con los sistemas de comunicación como estaciones de radio, TV y telefonía celular, en la caracterización del ambiente electromagnético de un hospital (Boisvert et al, 1991;Vlach et al, 1995). Sin embargo, pocos trabajos han sido realizados para caracterizar el ambiente magnético de baja frecuencia en hospitales (Spyropoulos et al, 2001;Hanada, 2007).…”

ResumenEl ambiente hospitalario es rico tanto en número como en diversidad de equipos electrónicos, que son susceptibles de recibir señales que posiblemente produzcan perturbaciones funcionales en ellos. El aumento de fuentes de campos electromagnéticos en tales ambientes, ha llevado a los investigadores alrededor del mundo a cuantificar el riesgo potencial de interferencia electromagnética en los equipos médicos. Para reducir los riesgos en estos equipos, es importante conocer el ambiente electromagnético que puede ser encontrado en los hospitales y clínicas. En este artículo se presentan los resultados de mediciones de campo magnético de frecuencia industrial realizadas en diferentes servicios de un gran hospital. Los resultados muestran que el campo magnético en algunos cuartos fue superior a los niveles de prueba de inmunidad establecidos por estándares internacionales para equipos médicos. Palabras claveEquipo médico, interferencia electromagnética, mapeo de campo magnético, frecuencia industrial.

“…Los mayores valores encontrados correspondían a transmisores de TV y radio FM. Vlach et al (1995), midieron el ambiente electromagnético dentro y fuera de cinco hospitales en Montreal, Canadá, verificando la influencia de las señales de TV y radio FM en el ambiente hospitalario. El valor máximo medido dentro del hospital fue de 0,76 V/m.…”

Equipo médico, interferencia electromagnética, campo eléc-trico, radiofrecuencia. Revista Tecnológicas [86]Medición del campo eléctrico ambiente de alta frecuencia en un hospital AbstractEach hospital has a unique electromagnetic environment. This can be extremely variable, particularly as a result of the great growth of wireless communications. This complex system is marked by numerous sources of electromagnetic energy both inside and outside hospitals and clinics. In this paper, the results of high frequency electric field measurements carried out in different departments of a large hospital are presented. The results show that electric field environment in all rooms measured was lower than radiated immunity test levels for medical devices established by international standard. KeywordsMedical equipment, electromagnetic interference, electric field, radiofrequency.
