This is the OSCAR data from last night, I attempted PS 1.0 over 12.0-13.0 (cmH2O) and AHI was good, but still a bit of fragmented sleep. Posting an update and always looking for suggestions. Thx.

that's a lot of change in one night but it doesn't look bad in comparaison to other night.
Why did you reduce the PS to 1? how did you feel with it? still a bit of fragmented sleep? maybe you can provide a zoomed view of your flow rate where you have arousal to check if it seems to be respiratory related or not?

[MrIvanDrago]

It was still fragmented, and a bit less comfortable, but still got thru the night. Not really sure what to do at this point. The 16.0/8.0 ps 4.0 seems to be the most comfortable, so maybe I should just stick with that, not sure really. 

I dropped down to PS 1.0 to see if it made a big difference, but it did not in terms of comfort or staying asleep.

Usually it is better to do only one change by night.
This night you changed epap and ps instead of doing epap 10 and the ps of 4.
I trust that you said that a epap of 8 prevent you of the "palatal prolapse and or mouth breathing" so yes EPAP of 8 should gave less arousal than above.

Hi CPAPfriend,


In regards to the 5% and 30% figures you mentioned for flow limits, I wanted to understand how this correlates to the Med, 95 and 99.5% figures in Oscar.

What is an acceptable or preferable Flow limit figure in Oscar, I dont understand how the percentages correlate to the one figure. When I look in Oscar there are always flow limits shown, but the Med is always 0.0 and the 99.5% is somewhere between 0.10 and 0.20 on a PS of 6.6 to 8 and goes upto about 0.45 on PS of 5. Are these these good figures or bad?

Thanks in advance.

Question about the ResMed AirCurve 10 Vauto trigger setting. 

Are there any potential downsides to using 'High' or 'Very High' trigger setting? I have been using the 'Very High' setting the last month and things are going well, but wanted to hear if there are any potential issues with using this setting vs. the default? 

Do the trigger settings impact respiratory rate in any way?

Thank you.

No problems - High and Very high can and does help eliminate central apnea in many people, myself included.

Quick question in regards to my therapy.

What would the difference be if I went from PS 4.0 to PS 5.0? Curious to the effect it may have on any arousals I have if at all?

PS is the pressure you get over EPAP to help you inspire, it reduce the effort you have to do to inspire. So more PS you put, less effort you have to do to inspire. So it helps to fix, flow limitaton, respiration effort, respiration effort arosal, snoring if it occurs when you inspire.
If PS is too high, you will be overventilate and get CA. 
So you have to look at your flow rate in detail to see if you have flow limitation, respiration effort etc so see if it makes sense to increase it to improve your therapy. You can also try it to see if you feel more confortable with a higher ps ans get better night. If you get CA at the beginning,  switch the trigger to high or very high.

Ok. My trigger is on very high and I haven't had any CA events in months since changing it. Currently my pressure is 16.0/10.0 PS 4.0. My flow limits are very low, ~0.7 99.5%. 

Wonder if it will make any difference with a PS of 5.0?
