Abstract
The present invention relates to a method and system in which a small stimulator unit which is designed to be mounted near the patient. A single cable connects the stimulator unit to the patient monitor. This cable both provides power to the stimulator unit, as well as 2-way data communication between the stimulator unit and the patient monitor. The patient monitor provides the user interface for the present invention, as well as other parameters such as heart rate and blood pressure.
