RE: David Clark - Therapy Thread
You're welcome. 
Here we have incredible people with good will to help others.
In my case, they imported my OSCAR data on different profiles on their own OSCAR so they took their time to analyze it. For me it is incredible to see how knowledgeable those guys are, I have been talking to all sleep study specialists in all my polysomnography tests and it is impressive to see they have no clue of many of the topics covered at the apnea board. 
I glad to be part of that nice community, newbie ,but well intentioned.
Regards

I think I'm understanding now that is what they had to have done. I thought I had made an error in the way I uploaded the files but no I'm thinking they would have to download the files and plug it into OSCAR to view. At first I was thinking I could upload it and they could just click and view.

David,

A) To share files the easiest way is to copy all of the contents (not just datalog) from your SD card and post them on a hosting site. Using datalog only will provide graphs but some settings and statistics will be wrong/missing making it tougher to interpret. 
B) You can't reference the drive. You need to download the files, put them in a folder, open OSCAR, click CPAP importer and then point it to the folder (won't automatically find it like it does an SD card). It should then load the information as if you were using an SD card. 

You commented in pearlpearls thread about having someone review your data. That is an option someone may take you up on but honestly your data looks pretty good so I doubt it would add any insight. When you get to this point the data loses its value and decisions need to be based on how you feel instead of what the data shows unless there is something obviously wrong with the data (high AHI, high flow limitation, really strange breathing etc). 

As a couple pointers it appears that min EPAP of 7 cm seems to keep most of your obstructive apnea at bay and the machine increases pressure if necessary. Changes in pressure settings at this point are unlikely to have a noticeable effect. If you feel high pressure is bothering you (wake up to high pressure or aerophagia) then you could try limiting max pressure. From the Feb 23rd data 6 PS appeared too high. 4 PS appears adequate and I wouldn't go over 5.

You appear to be in the play/fine tune state now. Changes you can consider are +/- 2 cm pressure, limiting max pressure, +/- 1 PS, adjusting trigger or cycle sensitivity. I would make only one change at a time, run the new setting for multiple days then base a conclusion on how you feel and then decide whether you keep the change or not.

Thank you Geer. I am pretty much just fine tuning at this point. Thank you for the pointers. My settings for the last..I don't know..3 or 4 days have been EPAP 9, IPAP 15 and PS 3 and everything is looking pretty good. There some cluster junk when I fist go to bed before I go to sleep and cluster junk if I get up for a bathroom break during the night but other than that it looks pretty smooth. I'll post a few graphs when I get home and can get to OSCAR in case you see anything you think I should tweak. 
Thanks again 
Dave

Here are screenshots of the last few nights. To me they look good but my eye is not that well trained. I feel fine. I'm not bounding with energy or anything but I'm not going to fall out just watching tv either. 
I don't know that anything needs to be messed with at this point but I'll put these here in case any of you spot something I need to address.

I think I mentioned before that I can get a little "knob turny" with the machine so I thought I'd post this so you can see what I've fiddled with since I got it in Jan. It seems to be doing pretty good now so unless anyone notices something they think I need to adjust I think I'm going to pull the knob off so I can't mess with it anymore.

RE: David Clark - Therapy Thread
All of your last four settings cover the same range with a lower starting pressure and result in very good results. With PS 3.0 over 9-15, the pressure moves about 1-cm. You seem to get a better AHI result with PS 3 than PS 4. It makes no observable difference whether your minimum EPAP pressure is 8.0 or 9.0. Do what is most comfortable for you. The settings are now in a very close range and working well, and it's time to choose your poison, use the machine and look at the data in a couple weeks. Focus on feeling well and don't worry about the data. FWIW, my last data download was February 14. My point is, at this point, the therapy will look after itself and you can focus on other things, or helping other members. Revisit your data after a few days of not looking at it, and start looking at longer-term trends.

Did you make another change other than increasing max pressure to 15 cm on Mar 27th? A change to one of the timing control settings (trigger sensitivity, cycle sensitivity, timin, timax etc)?

Just a little odd how you had 3 days averaging 4.91 AHI followed by 4 days averaging 1.62 AHI at effectively the same pressure/PS settings (your pressure rarely increases so I am assuming max pressure was not hit any of those nights).

No, I didn't make any of those adjustments. I did make adjustments to timin, timax back when there was an issue with the breathing pattern. That was on 3/17. I had a thread about that. I haven't touched any of the trigger, cycle or ti settings since then.
