Endotracheal tube apparatus
An apparatus for monitoring EMG signals of a patient's laryngeal muscles includes an endotracheal tube having an exterior surface and a first location configured to be positioned at the patient's vocal folds. A first electrode is formed on the exterior surface of the endotracheal tube substantially below the first location to receive EMG signals primarily from below the vocal folds. A second electrode is formed on the exterior surface of the endotracheal tube substantially above the first location to receive EMG signals primarily from above the vocal folds. The first and second electrodes are configured to receive the EMG signals from the laryngeal muscles when the endotracheal tube is placed in a trachea of the patient.
