En este artículo se presentan cuatro ensayos de compatibilidad electromagnética (CEM) realizados en el Laboratorio Cámara Anecoica de la Universidad de los Andes (Bogotá, Colombia) sobre ventiladores mecánicos fabricados por diferentes iniciativas colombianas para atender la emergencia sanitaria del COVID-19. Los cuatro ensayos se realizan de acuerdo con la norma de producto IEC 60601-1-2. Estos ensayos son: inmunidad radiada en la banda de 80 MHz a 1000 MHz, de acuerdo con la norma genérica IEC 61000-4-3; inmunidad radiada a frecuencias puntuales de 385 MHz, 450 MHz, 710 MHz, 745 MHz, 780 MHz, 810 MHz, 870 MHz y 930 MHz, de acuerdo con la norma genérica IEC 61000-4-3; emisiones conducidas, de acuerdo con la norma CISPR 11; y emisiones radiadas, de acuerdo con la norma CISPR 11. Se describen las normas utilizadas para realizar los ensayos, la configuración experimental empleada en cada ensayo, los resultados observados y las medidas de mitigación requeridas para pasar los ensayos. Se discuten los resultados y se sugieren medidas necesarias para promover el desarrollo de la compatibilidad electromagnética en Colombia. [ABSTRACT FROM AUTHOR]

This paper presents the results of four electromagnetic compatibility (EMC) tests carried out in the anechoic chamber of Universidad de los Andes (Bogotá, Colombia) on mechanical ventilators manufactured by different Colombian initiatives responding to the COVID-19 emergency. The four tests were carried out in accordance with the IEC 60601-1-2 product standard. The tests were the following: radiated immunity in the 80 MHz to 1000 MHz frequency, according to generic standard IEC 61000-4-3; radiated immunity at specific frequencies of 385 MHz, 450 MHz, 710 MHz, 745 MHz, 780 MHz, 810 MHz, 870 MHz and 930 MHz, in accordance with generic standard IEC 61000-4-3; conducted emissions, in accordance with the CISPR 11 standard; and radiated emissions, in accordance with the CISPR 11 standard. It describes the standards used to carry out the tests, the experimental setup used in each test, the observed results and the mitigation measures required to pass the tests. The results are discussed and necessary measures are suggested to promote the development of electromagnetic compatibility in Colombia. [ABSTRACT FROM AUTHOR]
