New VAUTO, strange settings pulmonologist

[Sleeprider]

As you can see, when inspiratory time rises, respiration rate falls and minute vent stays steady. The bottom line is that for you, TiMax is a comfort issue and has no impact on your net total respiration at these settings.

Thanks for these insights, I am learning a lot from this!

I think we are getting close to ideal settings. AHI is wonderful, and with the Ti-Max setting of 2.7, I no longer feel like I'm fighting the machine.

But I still sleep very restless though.
I do wonder if there is anything more we can do to get a more even depth of breathing. I have very long periods of irregular (periodic?) breathing.

There are some subtle central artifacts such as that periodic or "wavering" breath flow. The only thing I can think to try for that is to lower PS to 3.6. Consider it an experiment and note how your feel. I don't like just responding to the graphs because pretty charts is not what we're after, but yours look awfully good.

Lowering the PS unfortunately does not make any difference, it does not reduce the wavy breathing. I think the optimal settings for this device have been reached with this, don't you?

Sleeprider, once again I would like to thank you very much for the help you have given me. If I had had to figure all this out by myself it would have been a mess.

I'm glad we obtained a good results with comfortable, effective treatment. We don't always get things "picture perfect", but I suspect in time that oscillation will go away on its own as you adapt to the better ventilation. Thanks for working with this and all your feedback.

Let's hope so! However I am not so optimistic about this, because this problem also existed with the Autoset10. With all EPR modes this occurred to the same extent. Nor did it matter whether I was working with fixed or variable pressure.
