ABSTRACT:
A skin-mounted physiological recording electrode assembly has a foam pad having a front surface having a central recess and mounted to the skin, and a rear surface. A pad passage extends from the central recess to the rear surface. An electrode in the pad passage has a sensing end in the central recess and a connector end to which a clip attaches. The clip attaches to a lead wire connecting to a monitoring device. At least one deformation gauge is coupled to the rear surface of the foam pad, and may be a strain gauge, a bending sensor, or a combination of both. The electrode assembly may be used in a patient monitoring system having an electrode signal processor, sensor signal processors, a multiplexer, an A-to-D convertor, and a microprocessor programmed with an adaptive noise canceling algorithm. A method is taught of monitoring signals from at least two electrodes, generating and monitoring deformation signals which are correlated to the deformation of the foam pads, and making an adaptive noise canceling analysis of the electrode signals and the deformation signals to reduce or eliminate the noise component of the electrode signals.
