What is Claimed is:

1. A pressure support device (4) for providing pressure support therapy to a patient, the pressure support device comprising:

a pressure generating system (6,18) structured to generate pressure to provide pressure compensation to the patient via a patient circuit (12,14);

one or more sensors (22,27,28) structured to gather data indicative of disordered breathing events of the patient; and

a processing unit (24) structured to control the pressure generating system to provide a pressure compensation regimen to the patient; to analyze outputs of the one or more sensors while pressure support therapy is provided to the patient to determine if the pressure compensation regimen provided to the patient is effective to relieve one or more disordered breathing events, and to output an alert if it is determined that the pressure compensation regimen provided to the patient is not effective in relieving the one or more disordered breathing events.

2. The pressure support device of claim 1, wherein the processing unit is structured to determine that the pressure compensation regimen provided to the patient is not effective in relieving the one or more disordered breathing events when the one or more disordered breathing events persists for a predetermined period of time.

3. The pressure support device of claim 1, wherein the processing unit is structured to adjust one or more characteristics of the pressure compensation regimen, and wherein the processing unit is structured to determine that the pressure compensation regimen provided to the patient is not effective in relieving the one or more disordered breathing events when the one or more disordered breathing events persists through a predetermined number of adjustments to the one or more characteristics of the pressure compensation regimen.

4. The pressure support device of claim 3, wherein the adjustments to the one or more characteristics of the pressure compensation regimen include an increase in the pressure compensation provided to the patient.

5. The pressure support device of claim 1, wherein the one or more disordered breathing events include an obstructive apnea.

6. The pressure support device of claim 1 , wherein the one or more sensors are structured to sense an airflow waveform for a number of breaths of the patient, wherein the one or more disordered breathing events includes an epiglottic collapse in the patient, wherein the processing unit is structured to determine if the epligottic collapse is present in the patient based on the airflow waveform, and wherein the processing unit is structured to determine that the pressure compensation regimen provided to the patient is not effective in relieving the one or more disordered breathing events when it is determined that the epiglottic collapse is present in the patient.

7. The pressure support device of claim 1, further comprising:

one or more indicators (40);

wherein the one or more indicators are structured to provide one or more of a visual, an audible, and a tactile indication to the patient in response to the processing unit outputting the alert.

8. The pressure support device of claim 7, wherein the processing unit is structured to determine when the patient has aroused from sleep based on outputs of the one or more sensors, and wherein the processing unit is structured to wait until it has determined that the patient has aroused from sleep to output the alert.

9. The pressure support device of claim 1, further comprising:

a communication unit (34);

wherein, in response to the processing unit outputting the alert, the communication unit is structured to communicate the alert to an external device.

10. The pressure support device of claim 1 , wherein the one or more sensors include one or more sensors structured to determine a body or head position of the patient, wherein the processing unit is structured to determine if the patient is in a supine position based on outputs of one or more of the sensors, and wherein the processing unit is structured to output the alert only if the it is determined that the patient is in the supine position.

1 1. The pressure support device of claim 1 , wherein the alert includes a suggestion to use positional therapy.

12. A method of providing an alert for non-effective pressure compensation regimen, the method comprising:

providing a pressure compensation regimen to a patient;

receiving data from one or more sensors (22,27,28) structured to gather data indicative of disordered breathing events of the patient;

determining if one or more disordered breathing events of the patient are present based on the gathered data;

determining if the pressure compensation regimen provided to the patient is effective to relieve one or more disordered breathing events; and

outputting an alert if it is determined that the pressure compensation regimen provided to the patient is not effective in relieving the one or more disordered breathing events.

13. The method of claim 12, wherein determining if the pressure compensation regimen provided to the patient is effective to relieve one or more disordered breathing events includes determining that the pressure compensation regimen provided to the patient is not effective in relieving the one or more disordered breathing events when the one or more disordered breathing events persists for a predetermined period of time.

14. The method of claim 12, wherein providing the pressure compensation regimen to the patient includes adjusting one or more characteristics of the pressure compensation regimen, and wherein determining if the pressure compensation regimen provided to the patient is effective to relieve one or more disordered breathing events includes determining that the pressure compensation regimen provided to the patient is not effective in relieving the one or more disordered breathing events when the one or more disordered breathing events persists through a predetermined number of adjustments to the one or more characteristics of the pressure compensation regimen.

15. The method of claim 14, wherein the adjustments to the one or more characteristics of the pressure compensation regimen include an increase in the pressure compensation provided to the patient.

16. The method of claim 12, wherein the one or more disordered breathing events include an obstructive apnea.

17. The method of claim 12, wherein the one or more sensors are structured to sense an airflow waveform for a number of breaths of the patient, wherein the one or more disordered breathing events includes an epiglottic collapse in the patient, wherein determining if the pressure compensation regimen provided to the patient is effective to relieve one or more disordered breathing events includes determining that the pressure compensation regimen provided to the patient is not effective in relieving the one or more disordered breathing events when it is determined that the epiglottic collapse is present in the patient.

18. The method of claim 12, wherein outputting the alert includes providing one or more of a visual, an audible, and a tactile indication to the patient in response to the processing unit outputting the alert.

19. The method of claim 18, further comprising:

determining when the patient has aroused from sleep based on output of the one or more sensors, and

wherein outputting the alert includes waiting until the patient has aroused from sleep to output the alert.

20. The method of claim 12, wherein outputting the alert includes communicating the alert to an external device.

21. The method of claim 12, further comprising:

determining if the patient is in a supine position,

wherein outputting the alert includes outputting the alert only if the it is determined that the patient is in the supine position.

22. The method of claim 12, wherein the alert includes a suggestion to use positional therapy.

23. A non-transitory computer readable medium storing one or more programs, including instructions, which when executed by a computer, causes the computer to perform a method of providing an alert for non-effective pressure compensation regimen, the method comprising:

providing a pressure compensation regimen to a patient; receiving data from one or more sensors (22,27,28) structured to gather data indicative of disordered breathing events of the patient;

determining if one or more disordered breathing events of the patient are present based on the gathered data;

determining if the pressure compensation regimen provided to the patient is effective to relieve one or more disordered breathing events; and

outputting an alert if it is determined that the pressure compensation regimen provided to the patient is not effective in relieving the one or more disordered breathing events.
