Abstract
Described is a system including a sensor and a processing arrangement. The sensor measures data corresponding to a patient'"'"'s breathing patterns. The processing arrangement analyzes the breathing patterns to determine whether the breathing patterns are indicative of a REM sleep state. In another embodiment, the processing arrangement analyzes the breathing patterns to determine whether the breathing patterns are indicative of one of the following states: (i) a wake state and (ii) a sleep state. In another embodiment, a neural network analyzes the data to determine whether the breathing patterns are indicative of one of the following states: (i) a REM sleep state, (ii) a wake state and (iii) a sleep state. In another embodiment, the processing arrangement analyzes the data to determine whether the breathing pattern is indicative of an arousal.

23. A positive airway pressure system for delivery of a flow of breathable gas at a positive treatment pressure with respect to ambient air pressure delivered to an entrance of a patient'"'"'s airways in order to assist in treating a sleeping disorder in a patient, the positive airway pressure system comprising:
-
a flow generator which supplies a positive treatment pressure flow of breathable gases to the entrance of a tube, the tube directing the flow of breathable gases to the airway of a patient to provide the patient with the positive treatment pressure flow of breathable gases; a flow sensor located in a flow path of the positive treatment pressure flow of breathable gases, the flow sensor measuring data corresponding to the flow of breathable gases directed to the patient and indicative of the patient'"'"'s breathing patterns; and a processing arrangement which receives the measured data corresponding to the flow of breathable gases from the flow sensor and analyzes the data to determine the patient'"'"'s breathing patterns, the processing arrangement also determines whether to alter the pressure supplied to the airway of the patient based, at least in part, on the determined breathing patterns of the patient, wherein the processing arrangement applies a greater positive treatment pressure in an asleep state and a lesser positive treatment pressure in an awake state, wherein when the processor determines that the patient has transitioned between at least an awake state and an asleep state, the processing arrangement automatically increases a positive treatment pressure supplied to the entrance of the tube using a ramp system. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)

41. A method for treatment of a sleeping disorder in a patient using a positive airway pressure delivery system that delivers a flow of breathable gases at a positive treatment pressure with respect to ambient air pressure, the flow of breathable gases being delivered to an airway of a patient, the method comprising:
-
supplying, using a flow generator which generates a flow of gases to produce a positive pressure at or above a pressure at ambient air pressure, a flow of breathable gases to an airway of a patient; measuring, using a sensor, data indicative of the patient'"'"'s breathing patterns; determining, using a processing arrangement, an indication of the patient'"'"'s breathing patterns based on the data indicative of the patient'"'"'s breathing patterns; analyzing, using the processing arrangement, the indication of the patient'"'"'s breathing patterns to determine the sleep state of a patient; increasing a pressure of the flow of breathable gases, using the flow generator, to an airway of a patient when the patient is in an asleep state and an elevated upper airway resistance is detected; applying a lower pressure, using the flow generator, when the processing arrangement determines the patient is in an awake state based on the indication of the patient'"'"'s breathing patterns; and ramping an applied pressure to an elevated pressure when the processing arrangement determines that the patient transitions from the awake state to the asleep state based on the indication of the patient'"'"'s breathing patterns. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53)

54. A positive airway pressure system for delivery of a flow of breathable gas at a positive treatment pressure with respect to ambient air pressure delivered to an entrance of a patient'"'"'s airways in order to assist in treating a sleeping disorder in a patient, the positive airway pressure system comprising:
-
a flow generator which supplies a positive treatment pressure flow of breathable gases to be supplied to a patient; a flow sensor located in a flow path of the positive treatment pressure flow of breathable gases, the flow sensor measuring data corresponding to the flow of breathable gases directed to the patient and indicative of the patient'"'"'s breathing patterns; and a processing arrangement which receives the measured data corresponding to the flow of breathable gases from the flow sensor and analyzes the data to determine the patient'"'"'s breathing patterns, the processing arrangement also determines whether to alter the pressure supplied by the flow generator to the airway of the patient based, at least in part, on the determined breathing patterns of the patient, wherein the processing arrangement automatically delays the onset of a pressure increase to the patient when the processing arrangement determines that the patient is in an awake state, wherein the delay lasts at least until the processing arrangement determines that the patient is in an asleep state. - View Dependent Claims (55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67)
