ELECTRODE ASSEMBLY FOR SIGNALING A MONITOR

An electrode assembly adapted to be attached to the skin over selected facial muscle groups picks up signals to be analyzed by an anesthesia adequacy monitor that measures the level of awareness of a living animal, typically a human being. Also disclosed is a method of manufacturing the electrode assembly by printing a pattern of electrically conductive material through a silk-screen onto a flexible layer, and then coating the result with a non-conducting adhesive except at points corresponding to sensing points for the desired muscle groups. Finally, a method for using such sensing means is shown in maintaining an appropriate level of patient awareness under anesthesia.
