What are the domestic and international EMC (electromagnetic compatibility) standards for anesthesia machines?

The anesthesia machine integrates gas delivery, concentration monitoring, respiratory circuit, and patient monitoring functions. Its EMC standards comply with GB 9706.1, YY 0505 (domestic), and IEC 60601-1-2 (international). In the operating room environment, it needs to coexist with various devices such as high-frequency electrosurgical units and surgical navigation systems without interference. The standard pays special attention to ensuring that the electromagnetic emissions of the anesthesia machine itself do not affect other equipment, while its key functions such as gas flow control, anesthetic vaporizer control, and oxygen concentration monitoring remain accurate and stable under strong radio frequency interference. The reliability of solenoid valves, proportional valves, and various sensors is a key design focus.
