1. A set of electroencephalographic monitoring electrodes comprising:
- at least four electrodes, including a first electrode for the patient'"'"'s right temple, a second electrode for the patient'"'"'s left temple, a reference electrode, and a ground electrode, each electrode having a front, a back, and bottom, top, left, and right sides, each electrode back having a conductive region surrounded by an insulating region;
at least part of the back of each electrode being adhesive or sticky for application to skin;
each electrode having a label on the electrode front, each label being visually distinct from the labels of the other electrodes;
at least three of the at least four electrodes each having an upward-pointing pointed tab that is an extension of the insulating region extended in the same plane as the insulating region, the back of the tab not being adhesive or sticky, each tab having sufficient size to be grasped between a human forefinger and thumb;
the right temple electrode having on its right side a rightward-pointing jut, and the right temple electrode label having at the position of the rightward-pointing jut and pointing in the direction of the rightward-pointing jut a corresponding rightward-pointing alignment arrow;
the left temple electrode having on its left side a leftward-pointing jut, and the left temple electrode label having at the position of the leftward-pointing jut and pointing in the direction of the leftward-pointing jut a corresponding leftward-pointing alignment arrow;
the reference electrode having on its bottom side a downward-pointing jut, and the reference electrode label having at the position of the downward-pointing jut and pointing in the direction of the downward-pointing jut a corresponding downward-pointing alignment arrow;
wherein the planar distance between the conductive regions of the reference electrode and the ground electrode is enforced by a continuous insulating region between the two conductive regions, and said distance is at least the minimum effective distance for preventing electrical conduction between the two electrodes during cardiac defibrillation.

Abstract
Electrodes for use in electroencephalographic recording, including consciousness and seizure monitoring applications, have novel features that speed, facilitate or enforce proper placement of the electrodes, including aligning tabs and arrowed aligning juts, color coding, and an insulating bridge between reference and ground electrodes which ensures a safe application distance between the conductive regions of the two electrodes in the event of cardiac defibrillation. A method of using a set of four such electrodes is also disclosed.

9. A method of using a set of electroencephalographic monitoring electrodes comprising the steps of:
-
before or after either of the following two steps, peeling a right temple electrode from a backing and applying the right temple electrode to a patient having a forehead, a right temple, a left temple, an eyeline, and a right and left eye, such that an alignment arrow on a label on the right temple electrode aligns with the eye line of the patient and points to the right side of the patient'"'"'s right eye; after or before the preceding step or the following step, peeling a left temple electrode from a backing and applying the left temple electrode to the left temple of the patient such that an alignment arrow on a label on the left temple electrode aligns with the eye line of the patient and points to the left side of the patient'"'"'s left eye; after or before either of the preceding two steps, peeling a reference and a ground electrode from a backing and applying the reference electrode to the middle forehead of the patient approximately 1.5 inches above the patient'"'"'s eye line such that an alignment arrow on a label on the reference electrode aligns with a midline of the patient and points downward toward the patient'"'"'s nose, and applying the ground electrode to the left forehead of the patient at the distance from the reference electrode enforced by a continuous insulating region between two conductive regions of the reference electrode and ground electrode; applying electrode leads to the individual electrodes; and using biopotentials measured by the electrodes to monitor the electroencephalogram of the patient. - View Dependent Claims (10, 11, 12)
