Abstract： This paper investigates the electromagnetic compatibility testing methods cardiopulmonary resuscitation machines with multiple power modules from the perspective of inspection testing， based on national EMC testing stards medical electrical equipment. By analyzing the differences in immunity emission tests under various power modules （mains internal power）， it proposes an optimized strategy with the combination of independent module testing typical power mode testing. Experimental results indicate that the radiation emission levels are highest in the 30-200MHz frequency range when both the host respiratory modules are powered by mains， while electromagnetic interference is significantly reduced in dual internal power mode. This research improves the testing efficiency cost-effectiveness by refining the testing process， providing a theoretical foundation electromagnetic compatibility risk assessment stardized testing of similar medical devices.
