I got into trouble last night where I got up to the bathroom and when I went back to bed, I started having a lot of central apneas. My Resmed Airsense 10 just loafed along at a minimum pressure of around 8 and never really ramped back up to the level I was at before I got up. This caused a feeling of suffocation and my blood oxygen level was having wild swings from the 80s to the 90s. Before I had gotten up, I was cruising along at a maximum pressure of 10.8 and my Spo2 was fine, around 95. After struggling for over an hour, I just took the mask off, which is something I rarely ever do.
So my question is why did my machine not give me more pressure when I was in such distress? How does Resmed respond to CAs and would it be a good idea to increase my minimum pressure? Thanks!
If you are uncomfortable at 8 cm, by all means bump it up. Since you like it around 10 cm, I'd try it there. You can always change it later. An AS10 does not respond to CAs, the pressure increase is based on flow limitations.

ALL APAPS/CPAPS, and BiLevels without Backup (VAuto, "S" mode) are designed to do NOTHING in response to a central event.
Keep in mind that increased pressure and increased EPR/Flex/PS are among the things that often increase centrals in those that are proven to be susceptible. In general, we try to reduce these things to avoid having central apneas at the expense of increased obstructive events.

So if increased pressure tends to trigger CAs and I seem to be ok while asleep, I wonder if adding some ramp might help. I haven’t used ramp for quite some time.
DreamerDude, you have three threads and zero charts posted. How about putting up an Oscar detailed daily chart so we can see what we're dealing with, rather than guessing?

Hey Sleeprider, I totally get it. Makes all the sense in the world to get the info out there for you guys. You help a lot of people and to do so need as much information as possible. I think this is a great forum and until now haven't really participated. But I think I need help and I'm floundering. Below is a screenshot from last night. Please note that this morning I upped my pressure from 7.8 - 10.8, to 8.6 - 12, so consider I had it set to the former.
