Abstract

Claims (46)

1. A flow generator for use in a continuous positive airway pressure (CPAP) system or a non-invasive positive pressure ventilation (NIPPV) system, the flow generator comprising:

a motor configured to generate a supply of breathable gas for delivery to a patient;

at least one operation sensor;

at least one processor configured to:

receive signals from the at least one operation sensor;

during operation of the flow generator while the supply of breathable gas is delivered to the patient, detect an indication of a leak based on the signals from the at least one operation sensor;

based on the indication of the leak, generate a first message;

cause the first message to be communicated;

during operation of the flow generator while the supply of breathable gas is delivered to the patient, detect a further indication of the leak based on the signals from the at least one operation sensor;

based on the further indication of the leak, generate a second message; and

cause the second message to be communicated, wherein the second message is different from the first message.

2. The flow generator of claim 1 , wherein the first message and/or the second message includes an indication that the leak has been detected.

3. The flow generator of claim 2 , wherein the first message and/or the second message includes an indication that the leak has been detected.

4. The flow generator of claim 3 , wherein the first message and/or the second message includes tips to correct the leak.

5. The flow generator of claim 4 , wherein the tips include tips related to positioning and/or wearing a patient interface.

6. The flow generator of claim 1 , wherein the at least one processor is further configured to:

determine a leak duration based on the signals from the at least one operation sensor.

7. The flow generator of claim 6 , wherein the second message is generated further based on the determined leak duration.

8. The flow generator of claim 1 , wherein the first message is output to a display device that is coupled to the flow generator.

9. The flow generator of claim 8 , further comprising the display device.

10. The flow generator of claim 1 , wherein the first message is communicated to a different destination than the second message.

11. The flow generator of claim 1 , wherein the first message is communicated to a display device that is provided in the flow generator and the second message is communicated over an electronic data network to a remote computing device.

12. The flow generator of claim 1 , wherein the at least one processor is further configured to

during operation of the flow generator while the supply of breathable gas is delivered to the patient, detect a third indication of the leak based on the signals from the at least one operation sensor;

based on the third indication of the leak, generate a third message; and

cause the second message to be communicated, wherein the third message is different from both the first and second messages.

13. The flow generator of claim 12 , wherein

the first message includes a notice of the leak, the second messages includes tips for correcting the leak, and the third message is communicated to an external destination that is associated with a service provides and/or a physician.

14. The flow generator of claim 1 , wherein the at least one processor is further configured to:

determine an identifying feature that is associated at least one component of the CPAP system or NIPPV system; and

control at least one operating parameter of the flow generator based on the determined identifying feature.

15. The flow generator of claim 1 , wherein the flow generator is configured to deliver the supply of breathable gas to the patient via an air conduit and a patient interface, wherein the air conduit and the patient interface are fluidly coupled to the flow generator.

16. The flow generator of claim 15 , wherein the leak is a leak in the patient interface.

17. The flow generator of claim 15 , wherein the first message and/or the second message includes tips to correct the leak, wherein the tips include tips related to positioning and/or wearing a patient interface.

18. A method performed on a flow generator that includes at least one processor, the method comprising:

receiving signals from at least one operation sensor;

during operation of the flow generator and while a supply of breathable gas is delivered to a patient, determining an indication of a leak based on the signals from the at least one operation sensor;

based on the indication of the leak, generating a first message;

causing the first message to be communicated;

during operation of the flow generator while the supply of breathable gas is delivered to the patient, determining a further indication of the leak based on the signals from the at least one operation sensor;

based on the further indication of the leak, generating a second message; and

causing the second message to be communicated, wherein the second message is different from the first message.

19. The method of claim 18 , wherein the first message is communicated to a different destination than the second message.

20. The method of claim 18 , further comprising:

determining a leak duration based on the signals from the at least one operation sensor,

wherein the second message is generated further based on the determined leak duration.
