Abstract

Methods and systems involve coordinating therapies used for treating disordered breathing. Disordered breathing therapies may include cardiac electrical stimulation therapy and external respiratory therapy as well as other therapies for treating disordered breathing in a patient. The therapies delivered to the patient may be coordinated to enhance effectiveness of the therapy, to reduce therapy interactions, to improve patient sleep, or to achieve other therapeutic goals.

Claims

1. An automated method for treating disordered breathing, comprising:

controlling an external respiratory therapy delivered to a patient;

controlling a cardiac therapy delivered to the patient; and

coordinating delivery of the external respiratory therapy and the cardiac therapy to treat the disordered breathing.

2. The method of claim 1, wherein coordinating delivery of the external respiratory therapy and the cardiac therapy comprises:

sensing one or more conditions affecting the patient and associated with disordered breathing; and

coordinating delivery of the external respiratory therapy and the cardiac therapy based on the sensed conditions.

3. The method of claim 1, wherein coordinating delivery of the external respiratory therapy and the cardiac therapy comprises:

detecting the disordered breathing; and

coordinating delivery of the external respiratory therapy and the cardiac therapy based on the detected disordered breathing.

4. The method of claim 1, wherein coordinating delivery of the external respiratory therapy and the cardiac therapy comprises:

predicting the disordered breathing; and

coordinating delivery of the external respiratory therapy and the cardiac therapy based on the predicted disordered breathing.

5. The method of claim 1, wherein coordinating delivery of the external respiratory therapy and the cardiac therapy comprises:

sensing one or more conditions affecting the patient and indicative of therapy interactions; and

coordinating delivery of the external respiratory therapy and the cardiac therapy to adjust therapy interactions.

6. The method of claim 1, wherein coordinating delivery of the external respiratory therapy and the cardiac therapy comprises:

sensing one or more conditions affecting the patient and associated with an impact of the disordered breathing therapies on the patient; and

coordinating delivery of the external respiratory therapy and the cardiac therapy to adjust the impact of the therapies on the patient.

7. The method of claim 1, wherein coordinating delivery of the external respiratory therapy and the cardiac therapy comprises:

sensing one or more conditions associated with sleep; and

coordinating delivery of the external respiratory therapy and the cardiac therapy to adjust sleep quality.

8. The method of claim 1, wherein coordinating delivery of the therapies comprises increasing a first therapy and decreasing a second therapy.

9. The method of claim 1, wherein coordinating delivery of the therapies comprises coordinating delivery of the therapies based on usage of one or more of the therapies.

10. The method of claim 1, wherein coordinating delivery of the therapies comprises coordinating delivery of the therapies based on effectiveness of one or more of the therapies.

11. The method of claim 1, further comprising:

controlling one or more additional types of therapy delivered to the patient; and

coordinating delivery of the external respiratory therapy, the cardiac therapy and the one or more additional types of therapy to treat the disordered breathing.

12. A medical system for controlling therapy to treat disordered breathing comprising:

a respiratory therapy controller configured to control an external respiratory therapy delivered to a patient;

a cardiac therapy controller configured to control a cardiac therapy delivered to the patient; and

a processor coupled to the respiratory therapy controller and the cardiac therapy controller, the processor coordinating delivery of the external respiratory therapy and the cardiac therapy to treat the disordered breathing.

13. The medical system of claim 12, wherein the respiratory therapy controller is configured to control a positive airway pressure therapy.

14. The medical system of claim 12, wherein the cardiac therapy controller is configured to control a cardiac electrical stimulation therapy.

15. The medical system of claim 12, wherein the cardiac therapy controller is configured to control a cardiac pacing therapy.

16. The medical system of claim 12, wherein the cardiac therapy controller is configured to control a non-excitatory cardiac stimulation therapy.

17. The medical system of claim 12, wherein the cardiac therapy controller is configured to control an overdrive pacing therapy.

18. The medical system of claim 12, further comprising a sensor system configured to sense one or more conditions associated with the disordered breathing, wherein the processor is configured to coordinate delivery of the therapies based on the sensed conditions.

19. The medical system of claim 12, further comprising:

a sensor system configured to sense one or more conditions indicative of the disordered breathing; and

a detector configured to detect or predict the disordered breathing based on the one or more sensed conditions, wherein the processor is further configured to coordinate delivery of the therapies based on the detected or predicted disordered breathing.

20. The medical system of claim 12, further comprising a sensor system configured to sense one or more conditions indicative of therapy interactions, wherein the processor is configured to coordinate delivery of the therapies to adjust therapy interactions.

21. The medical system of claim 12, further comprising a sensor system for sensing one or more conditions associated with an impact of the disordered breathing therapies on the patient, wherein the processor is configured to coordinate delivery of the therapies to adjust the impact of the therapies on the patient.

23. The medical system of claim 12, wherein the processor is configured to increase a first therapy and decrease a second therapy.

24. The medical system of claim 12, further comprising an additional controller configured to control an additional type of therapy delivered to the patient, wherein the processor is configured to coordinate delivery of the external respiratory therapy, the cardiac therapy and the additional type of therapy to treat the disordered breathing.

25. A system for treating disordered breathing, comprising:

means for controlling an external respiratory therapy delivered to a patient;

means for controlling a cardiac therapy delivered to the patient; and

means for coordinating delivery of the external respiratory therapy and the cardiac therapy to treat the disordered breathing.

26. The system of claim 25, further comprising:

means for sensing one or more conditions associated with the disordered breathing; and

means for coordinating delivery of the therapies based on the sensed conditions.

27. The system of claim 25, further comprising:

means for sensing one or more conditions indicative of therapy effectiveness; and

means for coordinating delivery of the therapies to adjust therapy effectiveness.

28. The system of claim 25, further comprising:

means for sensing one or more conditions associated with an impact of the disordered breathing therapies on the patient; and

means for coordinating delivery of the therapies to adjust the impact of the therapies on the patient.
