1. An apparatus for monitoring electromyographic (EMG) signals of a patient's laryngeal muscles, comprising:
an endotracheal tube having an exterior surface and a first location configured to be positioned at the patient's vocal folds; and
only three conductive electrodes printed on the exterior surface;
wherein the only three conductive electrodes extend longitudinally along a length of the endotracheal tube and are laterally spaced apart to substantially surround a circumference of the endotracheal tube;
wherein one conductive electrode of the only three conductive electrodes is longitudinally staggered with the other conductive electrodes of the only three conductive electrodes.
