Abstract:
1. An apparatus for monitoring EMG signals of a patient's laryngeal muscles, comprising: an endotracheal tube having an exterior surface; conductive ink electrodes formed on the exterior surface of the endotracheal tube, the conductive ink electrodes configured to receive the EMG signals from the laryngeal muscles when the endotracheal tube is placed in a trachea of the patient; at least one conductor coupled to the conductive ink electrodes and configured to carry the EMG signals received by the conductive ink electrodes to a processing apparatus; and at least one automatic periodic stimulation (APS) electrode formed on the endotracheal tube, wherein the processing apparatus is configured to determine a position of the endotracheal tube based on signals generated by the at least one APS electrode.
