What are the domestic and international EMC (electromagnetic compatibility) standards for blood gas analyzers?

Blood gas analyzers are used for the rapid detection of blood pH, pCO2, pO2, etc., and must meet GB 9706.1, YY 0505 (domestic), and IEC 60601-1-2 (international) EMC standards. They employ electrochemical sensors (electrodes) with extremely weak signals (nA-pA level). The standards require that the electrode signals be stable and accurate in dynamic electromagnetic environments such as emergency rooms and operating rooms, unaffected by the switching on/off of nearby equipment (e.g., ventilators, electrosurgical units). Simultaneously, interference generated by the operation of internal fluid circuit peristaltic pumps, solenoid valves, etc., must not affect the sensor circuitry.
