Abstract
Described are a positive airway pressure system and method for treatment of a sleeping disorder in a patient. The system includes a generator, a sensor and a processing arrangement. The generator supplies airflow and applies a pressure at to an airway of a patient. The sensor measures data corresponding to patient'"'"'s breathing patterns. The processing arrangement analyzes the breathing patterns to determine whether the breathing patterns are indicative of at least one of the following patient'"'"'s states: (i) a regular breathing state, (ii) a sleep disorder breathing state, (iii) a REM sleep state and (iv) a troubled wakefulness state. The processing arrangement adjusts the applied pressure as a function of the patient'"'"'s state.

29. A positive airway pressure system for treatment of a sleeping disorder in a patient, comprising:
-
a generator supplying airflow and applying a pressure to an airway of a patient;
a sensor measuring data corresponding to patient'"'"'s breathing patterns; and
a processing arrangement analyzing the breathing patterns to determine whether the breathing patterns are indicative of one of the following patient'"'"'s states;
(i) a regular breathing state, (ii) a sleep disorder breathing state, (iii) a REM sleep state and (iv) a troubled wakefulness state, the processing arrangement adjusting the applied pressure as a function of the patient'"'"'s state,wherein, when the breathing patterns indicate state (iv), the processing arrangement sets a target pressure value and controls the generator to adjust the pressure to approach the target pressure value. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36)

37. A method for treatment of sleeping disorder in a patient using a positive airway pressure, comprising the steps of:
-
supplying an airflow to an airway of a patient using a flow generator;
measuring data corresponding to the patient'"'"'s breathing patterns;
analyzing with the processing arrangement the data corresponding to the breathing patterns to determine whether the breathing patterns are indicative of at least one of the following patient states;
(i) a regular breathing state, (ii) a sleep disorder breathing state, (iii) a REM sleep state, and (iv) a troubled wakefulness state;
using the processing arrangement, controlling the generator to adjust the supplied pressure as a function of the patient'"'"'s state; and
when the breathing patterns indicate state (iv), controlling the generator to adjust the supplied pressure to approach a target pressure value. - View Dependent Claims (38, 39, 40, 41, 42, 43, 45)
