A system and method are configured to adjust the tidal volume of the breathing of a subject. The subject is self-ventilating (breathes under her own power). The adjustment of tidal volume accomplished through use of the system and/or method may reduce hypertension (e.g., lower blood pressure), reduce stress and/or anxiety (and related maladies), improve relaxation, decrease sleep latency, improve sleep quality, address other sleep disorders, and/or provide other health benefits. The system and method are effective in adjusting tidal volume while the subject is awake and/or asleep.

1. A system configured to adjust a tidal volume of the breathing of a self-ventilating subject, the system comprising: one or more sensors that generate output signals conveying information related to one or more gas parameters of gas breathed by the self-ventilating subject;a positive pressure support device configured to provide a pressurized flow of breathable gas to an airway of the self-ventilating subject; anda processor configured to execute one or more modules, the one or more modules comprising: a parameter determination module configured to determine a breathing parameter from the output signals generated by the one or more sensors, wherein the breathing parameter reflects a tidal volume of the gas breathed by the self-ventilating subject;a control module configured to control the positive pressure support device to provide breathing cues to the self-ventilating subject that prompt the self-ventilating subject to breathe voluntarily in a way such that the tidal volume of the gas breathed by the self-ventilating subject is greater than or equal to a current target tidal volume, wherein the breathing cues include changes in a pressure of the provided pressurized flow of breathable gas; anda target module configured to adjust the current target tidal volume over time up and down between an initial target tidal volume and a final target tidal volume, such adjustment being based on the breathing parameter determined by parameter determination module. 2. The system of claim 1, wherein the one or more modules further comprise: a comparison module configured to compare the breathing parameter to a threshold that corresponds to the target tidal volume,wherein the control module is configured to adjust the breathing cues provided to the self-ventilating subject based on the comparison between the breathing parameter and the threshold by the comparison module. 3. The system of claim 2, wherein the one or more modules further comprise a timing module configured to determine from the one or more output signals generated by the one or more sensors an amount of time for which the self-ventilating subject has maintained the breathing parameter above the threshold. 4. The system of claim 1, wherein the target module is configured such that adjustment of the current target tidal volume over time up and down between an initial target tidal volume and a final target tidal volume includes determining compliance of the self-ventilating subject with the current target tidal volume for a predetermined period of time, and responsive to such determination, incrementing or decreasing the current target tidal volume. 5. The system of claim 1, wherein the self-ventilating subject breathes under his own power, wherein the breathing cues do not provide the tidal volume of the breathing, and wherein the breathing cues do not substantially supplement respiratory effort of the subject. 6. A method for adjusting a tidal volume of the breathing of a self-ventilating subject, the method comprising: providing a pressurized flow of breathable gas to an airway of the self-ventilating subject;generating output signals conveying information related to one or more gas parameters of gas breathed by the self-ventilating subject;determining a breathing parameter from the output signals, wherein the breathing parameter reflects a tidal volume of the gas breathed by the self-ventilating subject; andproviding breathing cues to the self-ventilating subject that prompt the self-ventilating subject to breathe voluntarily in a way such that the tidal volume of the gas breathed by the self-ventilating subject is greater than or equal to a current target tidal volume, wherein the breathing cues include changes in a pressure of the provided pressurized flow of breathable gas;adjusting the current target tidal volume over time up and down between an initial target tidal volume and a final target tidal volume, such adjustment being based on the breathing parameter. 7. The method of claim 6, further comprising: comparing the breathing parameter to a threshold that corresponds to the target tidal volume,wherein providing breathing cues includes adjusting the breathing cues provided to the self-ventilating subject based on the comparison between the breathing parameter and the threshold. 8. The method of claim 7, further comprising determining an amount of time for which the self-ventilating subject has maintained the breathing parameter above the threshold. 9. The method of claim 6, further comprising determining compliance of the self-ventilating subject with the current target tidal volume for a predetermined period of time, and responsive to such determination, incrementing or decreasing the current target tidal volume. 10. The method of claim 6, wherein the self-ventilating subject breathes under his own power, wherein the breathing cues do not provide the tidal volume of the breathing, and wherein the breathing cues do not substantially supplement respiratory effort of the subject. 11. A system configured to adjust a tidal volume of the breathing of a self-ventilating subject, the system comprising: means for providing a pressurized flow of breathable gas to an airway of the self-ventilating subject;means for generating output signals conveying information related to one or more gas parameters of gas breathed by the self-ventilating subject;means for determining a breathing parameter from the output signals, wherein the breathing parameter reflects a tidal volume of the gas breathed by the self-ventilating subject; andmeans for providing breathing cues to the self-ventilating subject that prompt the self-ventilating subject to breathe voluntarily in a way such that the tidal volume of the gas breathed by the self-ventilating subject is greater than or equal to a current target tidal volume, wherein the breathing cues include changes in a pressure of the provided pressurized flow of breathable gas;means for adjusting the current target tidal volume over time up and down between an initial target tidal volume and a final target tidal volume, such adjustment being based on the breathing parameter determined by the means for determining breathing parameter. 12. The system of claim 11, further comprising: means for comparing the breathing parameter to a threshold that corresponds to the target tidal volume,wherein the means for providing breathing cues includes a means for adjusting the breathing cues provided to the self-ventilating subject based on the comparison between the breathing parameter and the threshold. 13. The system of claim 12, further comprising means for determining an amount of time for which the self-ventilating subject has maintained the breathing parameter above the threshold. 14. The system of claim 11, further comprising means for determining compliance of the self-ventilating subject with the current target tidal volume for a predetermined period of time, wherein the means for determining compliance include means for incrementing or decreasing the current target tidal volume. 15. The system of claim 11, wherein the self-ventilating subject breathes under his own power, wherein the breathing cues do not provide the tidal volume of the breathing, and wherein the breathing cues do not substantially supplement respiratory effort of the subject.
