Abstract

Systems and methods delivering a breathing gas are provided. The methods include, for example, generating a first pressure level of breathing gas, increasing the pressure level of the breathing gas from the first pressure level to a second pressure level over a duration greater than one night'"'"'s sleep, and maintaining the second pressure level over a duration of at least one night'"'"'s sleep.

Claims

1. A method of delivering a breathing gas comprising:

generating a first pressure level of breathing gas;

increasing the pressure level of the breathing gas from the first pressure level to a second pressure level over a duration greater than one night'"'"'s sleep; and

maintaining the second pressure level over a duration of at least one night'"'"'s sleep.

2. The method of claim 1 wherein the step of increasing the pressure level from the first pressure level comprises determining whether the first pressure level has a duration equal to or greater than a first time period.

3. The method of claim 1 wherein the step of increasing the pressure level from the first pressure level comprises incrementally increasing the pressure level.

4. The method of claim 1 wherein the step of increasing the pressure level from the first pressure level comprises increasing the pressure level to an intermediate pressure level that is less than the second pressure level.

5. The method of claim 1 wherein the step of increasing the pressure level from the first pressure level comprises incrementally increasing the pressure level to an intermediate pressure level that is less than the second pressure level.

6. The method of claim 1 wherein the step of increasing the pressure level from the first pressure level comprises increasing the pressure level to at least one of a plurality of intermediate pressure levels that are less than the second pressure level.

7. The method of claim 1 wherein the step of increasing the pressure level from the first pressure level comprises incrementally increasing the pressure level to at least one of a plurality of intermediate pressure levels that are less than the second pressure level.

8. The method of claim 1 wherein the step of increasing the pressure level from the first pressure level comprises increasing the pressure level according to a ramp function.

9. The method of claim 1 wherein the step of increasing the pressure level from the first pressure level comprises linearly increasing the pressure level.

10. The method of claim 1 wherein the step of increasing the pressure level of the breathing gas from the first pressure level to a second pressure level over a duration equal to or greater than one night'"'"'s sleep comprises increasing the pressure level over a duration of a plurality of nights'"'"' sleep.

11. The method of claim 1 wherein the step of increasing the pressure level of the breathing gas from the first pressure level to a second pressure level comprises monitoring usage data.

12. The method of claim 1 wherein the step of increasing the pressure level of the breathing gas from the first pressure level to a second pressure level comprises monitoring usage data and increasing the pressure level of the breathing gas if the usage data exceeds or fails to exceed or reach a threshold value.

13. The method of claim 1 wherein the step of increasing the pressure level of the breathing gas from the first pressure level to a second pressure level comprises monitoring sensor data and increasing the pressure level of the breathing gas if the sensor data exceeds or fails to exceed or reach a threshold value.

14. The method of claim 1 wherein the step of increasing the pressure level from the first pressure level to a second pressure level comprises increasing the pressure level in non-linear pressure increments.

15. The method of claim 1 wherein the step of increasing the pressure level from the first pressure level to a second pressure level comprises increasing the pressure level in logarithmic pressure increments.

16. The method of claim 1 wherein the step of increasing the pressure level from the first pressure level to a second pressure level comprises increasing the pressure level in exponential pressure increments.

17. A system for delivering a breathing gas comprising:

a flow generator;

a controller having;

a first set of instructions that generate a first pressure level of breathing gas;

a second set of instructions that increase the pressure level of the breathing gas from the first pressure level to a second pressure level over a duration greater than one night'"'"'s sleep; and

a third set of instructions that maintain the second pressure level over a duration of at least one night'"'"'s sleep.

18. The system of claim 17 wherein the second set of instructions that increase the pressure level of the breathing gas from the first pressure level to a second pressure level over a duration greater than one night'"'"'s sleep comprises instructions that increase the pressure level over a duration of a plurality of nights'"'"' sleep.

19. A system for delivering a breathing gas comprising:

means generating a first pressure level of breathing gas;

means increasing the pressure level of the breathing gas from the first pressure level to a second pressure level over a duration greater than one night'"'"'s sleep; and

means maintaining the second pressure level over a duration of at least one night'"'"'s sleep.

20. The system of claim 19 wherein the means for increasing the pressure level of the breathing gas from the first pressure level to a second pressure level over a duration equal to or greater than one night'"'"'s sleep comprises means increasing the pressure level over a duration of a plurality of nights'"'"' sleep.

21. A method of delivering a breathing gas comprising:

generating a first pressure level of breathing gas;

monitoring usage data;

increasing the pressure level of the breathing gas from the first pressure level to a second pressure level if the usage data meets or exceeds a first threshold value; and

maintaining the second pressure level until the usage data meets or exceeds a second threshold value.

22. The method of claim 21 wherein the first and second thresholds have the same usage data value.

23. The method of claim 21 wherein the first and second thresholds have different usage data values.

24. The method of claim 21 further comprising the step of changing the second pressure level if the usage data meets or exceeds the second threshold value.

25. The method of claim 21 further comprising the step of reducing the pressure below the second pressure level if the usage data does not meet or exceed the second threshold over a time period.

26. The method of claim 21 further comprising the step of increasing the pressure above the second pressure level if the usage data meets or exceeds the second threshold value.
