Abstract

A subject is prompted to consciously alter one or more breathing parameters of respiration. To prompt the subject to alter one or more breathing parameters, a pressurized flow of breathable gas is provided to the airway of the subject. One or more gas parameters of the gas in the pressurized flow of breathable gas are adjusted to provide breathing cues to the subject that encourage the subject to consciously adjust respiration such that the one or more breathing parameters are altered. Information is also conveyed to the subject through a user interface that dynamically provides information to the subject about the breathing cues.

First claim

What is claimed is:

1. A system figured to prompt a subject to consciously alter one or more breathing parameters, the system comprising:
a positive pressure support device configured to generate a pressurized flow of breathable gas for delivery to the airway of a subject, wherein the pressurized flow of breathable gas comprises one or more gas parameters, wherein the positive pressure support device is further configured to provide breathing cues and adjusted breathing cues to the subject by adjustments of the one or more gas parameters of the pressurized flow of breathable gas, and wherein the breathing cues and the adjusted breathing cues prompt the subject to consciously make an adjustment to one or more breathing parameters of respiration of the subject; and
a processor configured to:
(i) control the positive pressure support device to generate the pressurized flow of breathable gas according to a predetermined pressure therapy regime;
(ii) determine one or more targets for the one or more breathing parameters according to the predetermined pressure therapy regime;
(iii) control the positive pressure support device such that the positive pressure support device provides the breathing cues and the adjusted breathing cues;
(iv) determine whether the one or more breathing parameters satisfy the one or more targets;
(v) responsive to the one or more breathing parameters not satisfying the one or more targets, adjust the breathing cues such that the conscious adjustment by the subject causes the one or more breathing parameters to satisfy an adjusted target, wherein each of the one or more targets and the adjusted target includes a different target curve shape; and
(vii) responsive to the breathing cues being adjusted and the one or more breathing parameters satisfying the adjusted target, readjust the breathing cues such that the conscious adjustment by the subject causes the one or more breathing parameters to satisfy the one or more targets.

2. The system of claim 1 , further comprising:
a user interface configured to communicate information to the subject related to the operation of the device and/or the pressurized flow of breathable gas,
wherein the user interface includes a display screen configured to provide text conveying the information,
wherein the processor is further configured to control the user interface such that the user interface provides text through the display screen,
wherein the text communicates information to the subject related to the meaning of the breathing cues provided to the subject, and
wherein the information related to the meaning of the breathing cues communicated by the user interface to the subject comprises an indication of whether a current breathing cue is prompting the subject to inhale or exhale.

3. The system of claim 2 , wherein the text provided through the display screen communicates information related to the meaning of the breathing cues that will be provided to the subject such that the text provided through the display screen corresponds to an upcoming breathing cue that has yet to be provided to the subject, wherein the information communicated by the display screen includes a countdown to the upcoming breathing cue.

4. The system of claim 2 , wherein the one or more gas parameters of the pressurized flow of breathable gas that are adjusted to provide the breathing cues to the subject comprise one or both of pressure and/or flow rate, wherein the user interface further includes one or more elements capable of generating sounds that are audible to the subject, and wherein the processor is further configured to control the user interface such that the one or more elements capable of generating sounds play word messages that indicate the meaning of the breathing cues provided to the subject.

5. The system of claim 2 , wherein the processor is further configured to facilitate selective disabling by the subject of the provision of information related to the breathing cues.

6. The system of claim 2 , wherein a user manually switches from a learning mode to a normal mode to selectively disable the provision of the meaningful text to the user through the user interface.

7. The system of claim 1 , wherein the one or more breathing parameters that the breathing cues prompt the subject to consciously make the adjustment comprise one or more of an inhalation flow rate, an inhalation period, an exhalation flow rate, an exhalation period, a tidal volume, a breathing rate, a breath period, a peak flow, a flow curve shape, or a pressure curve shape.

8. The system of claim 1 , wherein the predetermined pressure therapy regime is a period of increased tidal volume and/or reduced breath rate, a yoga breathing regime, a meditation breathing regime, a breathing regime for use during aerobic and/or anaerobic exercise, a Lamaze breathing regime, or a breathing regime for use during a pressure support therapy.

9. The system of claim 1 , wherein determining the one or more targets comprises incrementally increasing levels of the one or more breathing parameters, wherein incrementally increasing levels of the one or more breathing parameters start at one or more initial targets and incrementally increase to one or more final targets.

10. The system of claim 1 , wherein one or more of the target curve shapes are refined by a user via the user interface.

11. The system of claim 10 , wherein each of the one or more target curve shapes is refined by at least adjusting values of the curve's extrema.

12. The system of claim 1 , wherein the processor is further configured to: (vii) responsive to the one or more breathing parameters not satisfying the adjusted target, readjust the breathing cues such that the conscious adjustment by the subject causes the one or more breathing parameters to satisfy a further adjusted version of the one or more targets, wherein the further adjusted version of the one or more targets includes a different target curve shape.

13. The system of claim 1 , wherein the not satisfying of the one or more targets comprises exceeding the one or more targets too far.

14. A method of prompting a subject to consciously alter one or more breathing parameters, the method comprising:
generating, via a positive pressure support device, a pressurized flow of breathable gas for delivery to the airway of a subject, wherein the pressurized flow of breathable gas comprises one or more gas parameters;
controlling the pressurized flow of breathable gas according to a predetermined pressure therapy regime;
providing, via the pressurized flow of breathable gas of the positive pressure support device, breathing cues and adjusted breathing cues to the subject, wherein the breathing cues and the adjusted breathing cues prompt the subject to consciously make an adjustment to one or more breathing parameters of respiration of the subject;
determining one or more targets for the one or more breathing parameters according to the predetermined pressure therapy regime;
determining whether the one or more breathing parameters satisfy the one or more targets;
responsive to the one or more breathing parameters not satisfying the one or more targets, adjusting the breathing cues such that the conscious adjustment by the subject causes the one or more breathing parameters to satisfy an adjusted target, wherein each of the one or more targets and the adjusted target includes a different target curve shape; and
responsive to the breathing cues being adjusted and the one or more breathing parameters satisfying the adjusted target, readjusting the breathing cues such that the conscious adjustment by the subject causes th
