I'm on a bipap and trying an EPAP of 7cm and IPAP of 10 cm. That seems to take care of the flow limitations but I have about an hour of PLMS movements (so I assume bad sleep) in the 1st half of the night and a lot of sleep/wake transition CA clusters in the 2nd half. I think I have an arousal that k...

Yes, I think sleeping in prone position helps, but it's not comfortable to me and I can't stay there. Sleeping on back produces the worse results, I wear a vest with a ball on the back to prevent it. I sleep on my side 95% of the night. I think my UARS is taken care of while on my side and using a b...

Thank you for your response! I didn't notice there was a response until just now. I really appreciate it. Yes, I understand now that the this is a normal transition from exhaling to inhaling - I just couldn't find other flow rate data that was as exaggerated as mine seems to be at times. I do get a ...

Hi - Background: * I've been on CPAP for 5 years for a diagnosis of moderate OSA. I've used it consistently but I never feel refreshed in the morning. My AHI is fairly low and almost zero for obstructive events. My AHI usually ranged from 5-10 and was dominated by CAs. A took a deeper dive about 8 m...

Update. I thought I was only a side sleeper, but I video'd my sleep and I sleep on my back 50% of the time. I correlated this to my oscar data and the CSR stuff was only flagged when I was on my back. I slept with a backpack on last night to force side sleeping. While me sleep was horrible, CSR wasn...

My last sleep study had an AHI of 8.7 (composed of hypopneas 5.8 and central 2.9). My RDI was 21 (due to RERAs of 12.3). So not that bad - this was characterized as moderate sleep apnea. I've assumed my sleep quality has been so bad due to the # of arousals (31.7/hour) that were brought upon by apne...

Thanks for the explanations of waxing and waning and EPR. I tried a static pressure of 5.4cm last night and didn't have success. Still a lot CAs and CSR. Even much of the flow that's not tagged CSR has the same waxing and waning form. I was hoping a lower pressure would remove the CAs and waxing and...

BTW - I've turned off EPR because that has been a common suggestion I see in the threads. Now as I'm researching treatment-emergent central sleep apnea (the current best theory) and the ASV machine to treat it I'm confused why EPR shoudl be turned off. I think the ASV machine relieves pressure on th...

Sure! Here you go.

here's the CSR one. and total leak:

Thank you very much for replying. I do really appreciate it. I turned off EPR for last night and will keep it off tonight. I hear you about the doctor. I'm now armed with more info. He's on vacation until next week but I'm assuming he will schedule a sleep study where I'm using my CPAP if that's wha...

Thanks for replying! I live only 30' above sea level in the Bay Area in CA. I did try turning off my EPR last night based on some of the earlier threads on this topic. It didn't bother me that it was off (it wasn't noticeable to me), but I think I was so anxious about my new findings using oscar tha...

Hello - I'd very much appreciate some help with my Oscar data that's causing me a lot of anxiety - it's the very high amount of data flagged as CSR (periodic breathing). I've read many of the other questions and responses on this but most of ones I viewed don't seem like my situation - at least they...
