New to CPAP, High CA OSCAR review needed - ArmedStag - 10-14-2024
Hello, I'm 24 years old male from Japan. 162cm,70kg
Recently diagnosed with sleep apnea after a watchPAT test(returned AHI of 27) and waiting for at home PSG now.
I started CPAP therapy a few days ago and currently having trouble sleeping with mask on.
Also I am getting high amount of CA event and worried of having CSR-ish breathing
I want to know if these charts show any sign of serious condition, or is it merely a sign of me not being used to CPAP therapy.

Notice how all of your CSR flagged breathing lines up almost perfectly with increased mask leaks? The leaks are the most likely reason for the CSR. They are most likely false.
Here are some tips to prevent mask leaks: Mask Primer
- Mask leak solutions Hopefully you won't have any more CSR after you fix the mask leaks.

Welcome to the forum ArmedStag
That's not quite 5 hours of a single chart but I'd like you to switch over to cpap mode, the CSRs look legitimate but you're having flow limits with the the cas and leakage issues, leaks are also caused by low pressure, not only by too high of a pressure, so please let's set your machine to cpap mode @ 12cm of constant pressure with EPR on @ 1 fulltime (this will level off the leak issues and show a cleaner waveform). Please try this tonight for 30 to 45 minutes before bed. You will have a more natural form of breathing and you should feel a bit better, CAs should also subside. If it feels too difficult to exhale let's drop pressure by 1cm to 11cm.

Thank you for your advice!
But I don't really understand where of the chart CAs line up with leakage.
Also the machine didn't really flagged CSR, I am personally concerned if the waveforms look like CSR even if it is not flagged.
Can I ask for clarification?

Thanks for your advice!
I'm going to try CPAP mode before I sleep and see if it works.
Also, does it really look like CSR? The machine did not flag it as CSR.
Should I visit a cardiologist in case? I have no prior history of heart failure. I am extremely worried.

Sure ArmedStag. By "line up" look up and down vertically at all of the charts on the right hand side (Events Flags chart, Pressure chart, Flow rate chart, Flow limitations chart, leak chart, etc.) When events like CA's occur, OSCAR gives significant clues as to why they are occurring. Just line them up vertically by the particular time. Just about every CA you had occurs when you have leaks. CSR is a form of the most severe CA's.
Hopefully, when/if you get the leaks under control, your CA's will diminish.
Edit: you are correct. The machine only flagged CA's and not CSR. You don't have any CSR. My agologies.
