1. A method for titration of airway pressure in the treatment of hypoventilation, comprising:
- a processor examining a signal indicative of ventilation of a patient;
the processor examining a signal indicative of oxygen saturation of the patient;
based on an interaction between the ventilation and the oxygen saturation, the processor identifying a condition of hypoventilation; and
applying a pressure to the nasal passage of the patient if the condition of hypoventilation is identified.
