This forum is great but I am finding it difficult to search for cohesive threads. I like DIY stuff - am a Type 1 Diabetic and am doing the DIY loop insulin/CGM delivery program. Thus I was intrigued to read on this forum that we can download SW that will allow us to read our machine sim cards and produce detailed reports. I want to do this but am not sure how to get started. It appears the sleepyhead project is shut down. I would appreciate a point to a thread where this is discussed or info on what I need to do to get started. My only problem thus far after 7 days is that I am getting tremendous amounts of belly air which makes my mornings rough. It sounds like it could be a pressure issue based on what I have read but would like to produce detail reports which I have seen posted. Thanks!

The SleepyHead download site has been suspended. However, OSCAR is essentially the same, and can be downloaded. See link below:

OSCAR - Open Source CPAP Analysis Reporter

You need a PC or Mac with a SD carder. The SD card needs to be removed and locked, then you can transfer the data from the SD card to your computer to view it in OSCAR.

The condition you are describing is most likely Aerophagia. See this link for more information.

AEROPHAGIA CAUSES AND RESOLUTIONS

My suggestion would be to look at your Daily Report in Oscar and try to determine if there are any opportunities to reduce pressure. This should be not done arbitrarily, but after discussion with your machine provider. The link below may be helpful in understanding your AirCurve 10 machine.

AirCurve 10 Technical Manual

I am also a diabetic. If you have any specific questions, just ask.

Thank you very much for this information Sierra! I am sure I will have a few questions about OSCAR once I get started.

I did try a nasal pillow last night and sleeping on my side. Thus, I had little Aerophagia and remained less than 5 events (3.2). Had a total score of 84. The decrease was caused by a higher leak (seal) score - ~38 (L/min). However, this did not bother me in terms of sleeping and since I had no increase in events (this is the most important score - right?), I assume this is OK? I do have a message out to my provider about all of this. I have a slew of different mask types to try so hope to figure this out. Again, thank you.

Make sure you change the mask type in the machine configuration to match the type you are using. That will make the leak rate score more accurate. Ideally you want to keep leaks under 24 L/min. OSCAR has a good graph that shows how much you are leaking and when.

An AHI of 3.2 is OK. The treatment standard is less than 5. However many get under 1.0 when there is no central apnea involved. I do suffer from central events, and am pleased when I get under 3.

On masks I use a nasal mask with mouth taping to keep me from losing air out of my mouth during the night. A full face mask may make it easier to swallow air at higher pressures.
