RE: AHI help
That screams of being positional.
Does this happen frequently or is this a one off? Could you please provide a 2 minute views so we can see what's happening. What do you think happened?

RE: AHI help
Positional apnea! Read this wiki article and look at the similarity of your results with the example chart. Also note how easily this can be cleared up with a soft cervical collar or other device that prevents chin tucking. http://www.apneaboard.com/wiki/index.php...onal_Apnea

RE: AHI help
Stevemjc, you are using a Resmed Airsense 10 Autoset in fixed pressure mode with EPR 3. While I think a significant part of your solution is positional, I also think you should consider taking advantage of the automatic pressure adjustment capability of your machine, and to reduce EPR from 3 to 2 in order to clean up the CA events. If you're open to trying some optimization with auto pressure, the changes are:
Mode: Autoset Standard Minimum CPAP pressure: 8.0 Maximum CPAP pressure 14.0 EPR: Full-time at setting 2. These settings will allow your machine to increase pressure when it senses a reduction in flow leading to obstructive apnea, and it will also reduce pressure when centrals occur. The reduction in EPR is specifically to reduce the CA events. We normally expect those to diminish as you adapt to the machine, but the pressure difference between inhale and exhale (pressure support), can also lead to increases in CA due to a reduction in CO2 in your bloodstream from the increased ventilation.

RE: AHI help
Looking forward to seeing results. If clusters of OA continue, then a positional therapy will work.
