Abstract

The present invention provides a method for managing a patient having a sleep disorder, e.g. sleep apnea, snoring, sleep bruxism, upper airway resistance syndrome, etc. The method comprises monitoring physiological information from the patient, converting the physiological information to digital data, storing the digital data in a digital memory, identifying and characterizing epochs based on the digital data, and storing the identifying and characterizing information of the epochs in a digital memory. The method further comprises organizing the epochs according to an organization function that considers at least characterization information of the epochs, selecting an epoch based on the organizing of the epochs, and generating sound derived from the stored digital data associated with the selected epoch such that the patient hears the sound. In a specific embodiment, the physiological information monitored may include sound, e.g. respiratory sound emanating from the trachea, and/or tooth-grinding sounds.

Claims

1. (canceled)

2. A method for communicating information about a patient'"'"'s sleep, comprising the steps of:

capturing analog sound information spontaneously emitted by a patient during a period of time associated with a sleep period of the patient;

converting the analog sound information into a digital form;

storing the digital form of the sound information into memory;

dividing a portion of the period of time associated with the sleep period into a plurality of epochs, each of the plurality of epochs having an attribute;

determining a value of the attribute for each of the plurality of epochs;

selecting an epoch in which the value of the attribute satisfies a specified criterion;

retrieving from memory sound information associated with the selected epoch;

converting the retrieved sound information into an analog form;

outputting the analog form of the retrieved sound information to a listener.

3. The method of claim 2 wherein the attribute is pre-determined and is stored in memory.

4. The method of claim 2 wherein the listener is the patient.

5. The method of claim 2 further comprising the step of outputting information about the value of the attribute of the selected epoch synchronously with outputting the sound.

6. The method of claim 5 wherein the step of outputting information further comprises outputting information about the physiology of the patient'"'"'s respiration.

7. The method of claim 6 wherein the information about the physiology of the patient'"'"'s respiration includes a state selected from apnea, hypopnea, high respiratory effort, and snoring.

8. The method of claim 5 wherein the step of outputting information further comprises outputting a visual representation of sound intensity.

9. The method of claim 8 wherein, at a given moment, the step of outputting information further comprises outputting a visual element relating the sound being output at a given moment to the corresponding information being output at substantially the same moment.

10. The method of claim 9 wherein the sound being output and the corresponding information being output are less than 1 second apart.

11. The method of claim 2 wherein the step of dividing a plurality of epochs is based on the sound information.

12. The method of claim 4 further comprising the step of presenting information to the patient about an option to treat the condition associated with the output sound information.

13. The method of claim 2 wherein the step of selecting an epoch further comprises selecting ten or more epochs.

14. The method of claim 2 wherein sound information associated with an epoch is output based upon an input from the patient.

15. A system for communicating information about a patient'"'"'s sleep, the system comprising:

a memory for storing in digital format sound information spontaneously emitted from a patient during a period of time associated with a sleep period of the patient;

means for dividing a portion of the period of time associated with the sleep period into a plurality of epochs, each of the plurality of epochs having an attribute;

means for determining a value of the attribute for each of the plurality of epochs;

means for selecting an epoch in which the value of the attribute satisfies a specified criterion;

means for retrieving from the memory the sound information associated with the selected epoch;

means for converting the retrieved sound information into an analog form,

means for outputting the analog form of the retrieved sound information to a listener.

16. The system of claim 15 wherein the means for selecting an epoch includes a user interface.

17. The system of claim 16 wherein the user interface displays references to epochs of the period of time associated with the sleep period.

18. The system of claim 17 wherein the user interface further displays information about a value of an attribute of a plurality of epochs having references displayed.

19. The system of claim 18 wherein the display of references to epochs is organized based on the value of an attribute of the epochs.

20. A method for communicating information about a patient'"'"'s sleep, the method comprising the steps of:

capturing analog sound information spontaneously emitted by a patient during a period of time associated with a sleep period of the patient;

converting the analog sound information into a digital form;

storing the digital form of the sound information into memory;

dividing a portion of the period of time associated with the sleep period into a plurality of epochs, each of the plurality of epochs having an attribute;

determining a value of the attribute for each of the plurality of epochs;

ranking the plurality of epochs based at least in part on the values of the attribute for the plurality of epochs;

selecting an epoch based on the ranking;

retrieving from memory sound information associated with the selected epoch;

converting the retrieved sound information into an analog form;

outputting the analog form of the retrieved sound information to a listener.

21. The system of claim 20 wherein the attribute is the anticipated psychological impact upon the listener of hearing the outputting of the retrieved sound.

22. The system of claim 20 wherein the listener is the patient.

23. The system of claim 20 wherein the values of the attribute for the plurality of epochs are based on a model of the listener.

24. The system of claim 23 wherein the listener is the patient.

25. The system of claim 24 wherein the model of the listener includes comorbidities of the patient.

26. The system of claim 24 wherein the model of the listener includes an estimate of the compliance of the patient with a therapy.
