What are the domestic and international EMC (electromagnetic compatibility) standards for hemodynamic monitors?

Hemodynamic monitoring devices (e.g., pulse contour analysis, transpulmonary thermodilution devices) must comply with GB 9706.1, YY 0505 (domestic), and IEC 60601-1-2 (international) EMC standards. They acquire weak physiological signals through arterial pressure sensors, temperature sensors, etc., and calculate parameters such as cardiac output using complex algorithms. The standards require these precision measurements to remain accurate even in highly disruptive environments such as operating rooms (especially during electrosurgical procedures), with no distortion of arterial pressure waveforms and no drift in temperature measurements. The connection interface between the device and external sensors (e.g., Swan-Ganz catheters) is a key area for protection.
