Thanks for the reply. I will discuss this with my specialist the next time.

Hi Sierra.. Thank you for introducing me to the term "Sleep onset Apnea". I read some posts about that and it indeed describes my issue. I am eagerly waiting to re-use the dreamstation with Oscar once the foam issue is settled. F&P Sleepstyle do flag some events as Central Apnea, it could be that they have improved their app recently. I have also felt that F&P sleepstyle is more comfortable to use than the dreamstation, perhaps due to their Senseawake feature.

I still have my 6 month old Philips Respironics auto CPAP with me, cleaned and neatly packed for the re-call.

Hi Sierra, Thank you very much for the reply. Yes, I had removed the mask because I had the choking sensation. I don't know whether that sensation is real or mental. I will increase the minimum pressure and see how that works.

Hi Sierra, Please see the screen shots for January 10.

Thank you for your reply. I had posted my Oscar report as your reply. But can't see it here. Please let me know which particular figure in the Oscar report should I concentrate on?

Yes I have the Dreamstation SD card. Even though I uploaded the screenshot here, I don't see it anymore. So uploading again.

Yes, I have the Dreamstation SD card.

I am 40 years old ( 5' 10'' with 96 KG weight ) . It began when I started waking up from sleep with choking sensation every night in the first 30 minutes of my sleep. After the apnea like event happens once, I am able to sleep the entire night without further awakening. But the choking sensation itself was scary and my doctor suggested sleep study. I was diagnosed with moderate obstructive sleep apnea in 2019 ( 14 AHI ). Initially they suggested the oral appliance and I gave it a try. It did not solve my problem. I still choked and the first thing that I do on waking up with the sensation was to throw the appliance away. After 5 t o 6 months of unsuccessful trial and 2000 dollars later, I went for another sleep study. This time I had 15 AHI and opted for CPAP therapy. I intended to buy Dreamstation Auto CPAP as I found it quite cheap in Amazon. During the 1 month machine trial( December 2020), I didn't had any issues for the first 10 days, but after that I started having the choking sensation ( in the fist 30 minutes of sleep ). My sleep specialist told that it will go away after some time. I decided not to go with the sleep clinic's 2500 dollar Dreamstation and bought my own dreamstation for 45 dollars( Canadian). With the Dreamstation my AHI had come down to 2 by June 2021, but I still had the choking sensation 30 minutes into sleep. I tried pressure settings of 4 to 7 minimum to 11 to 20 max . I have also seen that my AHI shot up when I increased the minimum pressure to 6 or 7. After Dreamstation got recalled, I bought Fisher and Paykel sleepstyle Auto and it is currently showing my AHI as 0.7 ( 9 hours of sleep with a pressure range of 4 to 15 cm H2O). But I still have the one time choking sensation 30 minutes into sleep. Did anyone else had such an experience? I am starting to think that I may have some other medical condition causing it.
