1. 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; anda 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, wherein the processing arrangement determines the patient has transitioned between an awake state and an asleep state when a combination of obstructions are detected. 2. The system of claim 1, wherein the combination of obstructions are a regular period of obstructions. 3. The system of claim 1, wherein the combination of obstructions are three or more obstructions. 4. The system of claim 3, wherein the obstructions are apneas. 5. The system of claim 1, wherein the obstructions are hypopneas. 6. The system of claim 1, wherein the obstructions are apneas. 7. The system of claim 2, wherein the regular period of obstructions comprises at least three apneas. 8. The system of claim 1, wherein when the processing arrangement determines during an asleep state that the patient is experiencing an elevated upper airway resistance, the processing arrangement increases the pressure applied to the airway of the patient. 9. The system of claim 1, wherein when the processing arrangement determines during an asleep state that the patient is experiencing a hypopnea event, the processing arrangement increases the pressure applied to the airway of the patient. 10. The system of claim 1, wherein when the processing arrangement determines during an asleep state that the patient is experiencing an apnea event, the processing arrangement increases the pressure applied to the airway of the patient. 11. The system of claim 1, wherein when the processing arrangement determines that the patient has transitioned to an awake state from an asleep state, the processing arrangement lowers the pressure applied to the airway of the patient. 12. The system of claim 11, wherein the awake state is a troubled wakefulness state. 13. The system of claim 1, wherein the pressure is increased using a ramp system. 14. 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; anda 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, wherein the processing arrangement determines the patient has transitioned between an awake state and an asleep state when three or more obstructions are detected. 15. The system of claim 14, wherein the obstructions are hypopneas. 16. The system of claim 14, wherein the obstructions are apneas. 17. The system of claim 14, wherein the three or more obstructions are a regular period of three or more obstructions. 18. The system of claim 14, wherein when the processing arrangement determines during an asleep state that the patient is experiencing an elevated upper airway resistance, the processing arrangement increases the pressure applied to the airway of the patient. 19. The system of claim 14, wherein when the processing arrangement determines during an asleep state that the patient is experiencing a hypopnea event, the processing arrangement increases the pressure applied to the airway of the patient. 20. The system of claim 14, wherein when the processing arrangement determines during an asleep state that the patient is experiencing an apnea event, the processing arrangement increases the pressure applied to the airway of the patient. 21. The system of claim 14, wherein when the processing arrangement determines that the patient has transitioned to an awake state from an asleep state, the processing arrangement lowers the pressure applied to the airway of the patient. 22. The system of claim 14, wherein the awake state is a troubled wakefulness state. 23. The system of claim 14, wherein the pressure is increased using a ramp system. 24. 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; andincreasing 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, wherein the indication of the patient's breathing patterns is a pattern of at least three obstructions. 25. The method of claim 24, wherein the obstructions include at least one apnea. 26. The method of claim 24, wherein the obstructions include at least one hypopnea. 27. The method of claim 24, wherein pattern of at least three obstructions are a regular period of three or more obstructions. 28.
