Hello,
This is my first post using OSCAR (1.3.0 Beta)
I have been using the ResMed AirSense 11 since July 9th. I had my sleep study in March and the Titration procedure at the end on June. I wasn't sure how to save pdf files as a screen shot so I'll attach as pdf attachment.
My original sleep study included significant central apneas as well as obstructive. The Titration procedure called them treatment emergent. Since using the CPAP machine my AHI numbers have not been good as far as central events. It seems to be working for Obstructive events.
So I'm including the sleep study summaries and an OSCAR screenshot. I feel like the machine is not helping with the central events. Would anyone be willing to look at my data and give me an opinion on what to do?1

Ok I since figured out how to save pdf as image. Here goes...

How nice is that AS11? Don't get too used to it because I think, with a high degree of certainty, that you likely need a ASV machine.
Your Centrals composed 114 of 282 apneic events, and your AS11 results with a low (1) EPR still represent that.
Try EPR = 0 but it shouldn't make a big difference and you need to start complaining to your doctor.
Phil, being that this is an AS11 with a high number of central apneas could you check for any unexpected anomalies in the SD card data.
Please make a complete zip of the entire SD card and place it in a dropbox for further validation. Include your username and "AS11" in the filename so we can get back to you.
Can a Mod please add AS11 to the thread name.
RE: AS11 - Need interpretation and opinion
I believe it was tmiller who sent us one of our first sets of data, and I'm happy to look at another sample.
I'd like to have all the AS11 owners take a look at the settings section of OSCAR v1.3.0-beta.2 and compare with the machine's display, and take a look at the times to see if they match the times of their sleeping. Please report any errors or oddities either here or in the Beta forum, if possible.

You can zip your OSCAR_Data directory and upload it to
my Dropbox folder. Please include your forum name in the zip file name.
I'll pass the file on to Pholynyk.

Your titration study did not reproduce the important information of the actual titration, but I suspect centrals were a problem. Your diagnostic study shows a significant central apnea component, and we can usually figure that with that much CA the hypopnea was also mixed or central. I agree with Gideon, you will ultimately end up with ASV. It is common practice to diagnose all sleep disordered breathing as obstructive, even when a significant component of central is present. This allows for CPAP to be trialed, and you advance to bilevel or bilevel with backup only after failing CPAP due to insurance requirements. This wiki describes the process
http://www.apneaboard.com/wiki/index.php...P_Machines Let's just say you are likely to fail CPAP and required advanced therapy, and the sooner you bring the issue of the central apnea with therapy to your doctor's attention, the sooner you can be scheduled for a titration of bilevel and bilevel with ASV which will fix everything and bring your AHI to less than 2/hour. You are a healthy individual based on the profile and not a typical obstructive sleep apnea patient. Let us know what your doctor says.
RE: AS11 - Need interpretation and opinion
Thank you all for your inputs. I agree with your analysis. I lost several days of data probably because I forgot to unlock the sod card when I put it back in the machine. I’ll upload my sad card data after I’m sure the machine is adding data to the card.
RE: AS11 - Need interpretation and opinion
I made sure the AS11's SD card was unlocked and I used the machine for almost 8 hours last night. Nothing was on the SD card after 8/22. There is a folder for 8/23 but it is empty. Anyone have any ideas? The myAir app is still updating but that's through wifi.
RE: AS11 - Need interpretation and opinion
What size is your SD card? These cards can(and do) go bad in a heartbeat, have you tried using another card? Since you have the newer AS11, is there any documentation that lists the size limit of the SD card that it can use? The S9s & A10s had a 32 GB maximum size.
RE: AS11 - Need interpretation and opinion
The card is in my reader at home so I did a remote access and the SD card capacity is 3.69 GB, used is 152 MB and 3.54 GB free so the card is not full. I wonder if the old unplug/plug in trick might work. I'll try it tonight. If that doesn't work I'll message the company that supplied the machine.
