First, thanks to sawinglogz for getting my son's machine fully supported on Oscar!
Second, I think I should give some additional info besides the Oscar screenshot.
My son was diagnosed in 2014 with UARS (Upper Airway Resistance Syndrome) via a thorough PSG that did NOT show any central apneas. I point that out because it seems he's having a lot of centrals now, and we believe they are caused by the ASV. His respiratory tech says to turn on the "Backup Rate" to get rid of these. However, he tells me that this causes him a lot of problems. The pressure "goes crazy" ... the pressure goes very high and his abdomen fills with air. (I think he referred to it as "pressure cycling"?) It also wakes him. I understand that the Backup Rate detects and attempts to cut off central apneas; I assume a more proactive and effective approach is to prevent those centrals from happening in the first place, if possible. Therefore I am considering looking into EERS. (thanks again for that link, sawinglogz)
Ultimately, if the centrals persist, my son would even consider weaning off the PAP altogether. He was doing better before starting it.
His therapist says that, other than the centrals, his "numbers are fine". But he has felt worse since starting CPAP (around 2015) and then ASV shortly after. My son and I believe that, even if we fix the Centrals, his RERAs (Respiratory Effort Related Arousals) will still be there. It is my understanding that Oscar reports Flow Limitations, which MAY correlate with RERAs, but not necessarily. A PAP machine simply can't measure the brain activity that reflects an arousal, obviously. So one of our objectives is to reduce (eliminate) the RERAs.
Anyway, I've attached a screenshot of one night (a fairly nasty one , AHI 32). I welcome any suggestions. Again, I know the centrals are prominent, and may need to be eliminated, but ultimately we believe it's the RERAs (possibly indicated by Flow Limitations, or perhaps only detectable by looking at the actual waveforms - I don't know) ... that must be fixed.
Thanks
