1. A method of operating a continuous positive air pressure system (CPAP), the method comprising:
- providing continuous positive airway pressure from a flow generator that includes an impeller, the provided continuous positive airway pressure provided to a patient interface that communicates the continuous positive airway pressure to at least one upper airway of a patient where the continuous positive airway pressure provided to the at least one upper airway acts to splint open the at least one upper airway, the patient interface being a full-face interface or nasal interface configured to engage with the face of the patient, the provided continuous positive airway pressure controllably set, by the flow generator, for at least a first treatment pressure of between 4 and 20 cmH2O;
detecting, via a sensor, sounds output by the patient while the continuous positive airway pressure is provided to the patient from the flow generator at the first treatment pressure;
generating a signal in response to the detected sounds output from the patient;
distinguishing, via at least one processor, indications of sounds of speech that are from the patient attempting to speak from among other sounds that are represented in the generated signal; and
reducing the continuous positive airway pressure by controllably setting, by the flow generator, to a second treatment pressure from the first treatment pressure in response to the distinguished indications from the patient to thereby facilitate speech by the patient while the flow generator is in use at the reduced second treatment pressure.

Abstract
A method of operating a device for treating sleep disordered breathing (SDB), wherein the device provides continuous positive airway pressure during sleep, includes applying a treatment pressure to a patient, monitoring the patient for speech output, generating a signal in response to detected speech of the patient, and, in response to the signal, reducing the treatment pressure applied to the patient.

21. A method of operating a device for treating sleep disordered breathing (SDB), the method comprising:
-
supplying continuous positive airway pressure produced by a mechanical flow generator to a patient via a patient interface that communicates with at least one upper airway of a patient, the continuous positive airway pressure that is communicated to the at least one upper airway of the patient configured to splint open the at least one upper airway of the patient, the patient interface configured to engage with the face of the patient, the continuous positive airway pressure provided at a treatment pressure of between 4 and 20 cmH2O at a first level; and while the continuous positive airway pressure is supplied from a flow generator to the patient via the patient interface at the first level; monitoring the patient for an attempt at speech output; generating a signal in response to the attempt at speech output from the patient; and in response to said generated signal, decreasing the provided treatment pressure by controllably setting, by the flow generator, to a second level from the first level to thereby facilitate speech by the patient without the pressure being supplied at the first level. - View Dependent Claims (22, 23, 24)

25. A device for treating sleep disordered breathing (SDB), the device comprising:
-
a flow generator that includes an impeller, the flow generator configured to provide, by using the impeller, continuous positive airway pressure at a set treatment pressure that is at a first level; a patient interface structured to interface with at least one upper airway of a patient to deliver the continuously provided pressurized air to the at least one upper airway the patient interface configured to engage with the face of the patient, the patient interface being a full-face interface or nasal interface, the delivered continuously provided pressurized air to splint open the at least one upper airway; a sensor configured to detect sounds by the patient when the patient interface is engaged to the face of the patient and the continuous positive airway pressure is being provided; and a controller, coupled to the sensor, configured to; determine, during application of the continuous positive airway pressure at the first level, when an attempt of speech by the patient occurs based on the detected sounds, and cause the flow generator to reduce the set treatment pressure from the first level to a second level provided by the flow generator when the attempt of speech is determined, the reduction of the treatment pressure facilitating speech by the patient while the flow generator provides the treatment pressure at a second level. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)
