Let me tell you about my first experience with ASV, which was very positive . Before I do that, I need to tell you the context of yesterday night. I had insomnia yesterday. I was very anxious last night because I had important things to do in the very early morning (way more than usual). When I know I have to do things in the morning and see people, I just can’t sleep. I even took zolpidem pills (I no longer consume benzodiazepines) and still could not sleep until 5:30 AM, when I finally got to sleep something.

In the meantime, I tried several masks with my ASV. I was having insomnia anyway, so I decided to try all my masks. I tried full-face, nasal, and pillow masks. From all of them, the pillow mask (with mouthtape) was the most comfortable. When I was using APAP, pillow masks were horrible; there was too much direct pressure inside my nose, and I could not exhale easily. I felt claustrophobic, but now that I can exhale easily with ASV, I love them. I feel like I can finally exhale. ASV is so comfortable with the pillow mask that it practically does the breathing for me, and leaks with the pillow mask are very manageable. I will never go back to APAP again. Never again. Nightly, anxious UARS persons should stay away from APAP.

So here’s my OSCAR data screenshot from 5:30 AM to 8.50 AM, It seems I had a deep sleep from 6:00 AM to 8:00 AM, Those high flow limit spikes were because of some leaks when I was probably scratching my nose and air leaked. So not all the flow limit spikes are because I had breathing problems:



Here’s a close-up of the waveforms when I was in deep sleep, I'm aiming to perfect them and make them even rounder:

If you have any tweak settings recommendations, please don't hesitate to suggest them to me. I know just 3 hours of data is very little, but if you have UARS and you are using ASV, please share your setting, or if you have ANY experience with ASV, any suggestions are well welcomed.

My results are similar to yours every night. My AHI is often 0 and it's uncommon that it would ever be over .3. And I feel a thousand times better than I ever did on the APAP. I think you made the right decision!

You're comfortable, so I'll let you experiment with it, but you are comfortable, and nothing is out of control.  I think you can reduce PS max to 8.0 and rarely hit it.  That will satisfy the minimum difference between PS min (3.0) and max (8.0) that Resmed requires for the ASV.
