ABSTRACT:
A system and device for mitigating interference in patient physiological monitoring is provided, particularly in surgical environments. One or more sets of electrodes are placed on a patient's body and connected to corresponding terminals of an input extender. The terminals of the input extender are connected to a set of signal wires encased by a ferrous shielded cable. The ferrous shielded cable connects to a signal processing unit, which includes a differential amplifier and an active drive topology to drive the shield with a common mode signal. The signal processing unit connects to physiological monitoring equipment.
