Abstract: A system including a position-sensing medical tube and sensor electronics is provided in accordance with an embodiment of the present invention. The position-sensing medical tube comprises a medical tube and position-sensor apparatus coupled to the medical tube in a predetermined location. The position-sensor apparatus is adapted to communicate with the sensor electronics so as to provide information dependent on the relative position of the medical tube. Movement of the medical tube, and thus the coupled position-sensor apparatus is sensed by the sensor electronics. The sensor electronics interprets state-data as that the medical tube has moved and responds in a predetermined way, such as, but not limited to, triggering an alarm and turning off a process.
