1. A system for delivering a flow of breathing gas to an airway of a patient comprising:

  • a pressurizing flow module that generates a pressurized flow of breathing gas;

    a patient circuit coupled to the pressurizing flow module configured to communicate the flow of breathing gas to an airway of a patient;

    a sensor adapted to monitor a characteristic of a breathing pattern of the patient; and

    a controller that communicates with the sensor and configured to increase a fraction of inspired carbon dioxide if the characteristic exceeds an upper threshold value and to provide servo-ventilation if the characteristic is less than a lower threshold value, wherein the upper threshold value and the lower threshold value are changed based on the monitored characteristic of the breathing pattern of the patient.
