As jlk said, it looks like you had a pretty good night except for the leaks. Four events overnights, none of them particularly long, and only two of them relatively close together seems pretty good. Here's hoping that future nights look as good. How does the 5.5 hours of sleep/time in bed correspond to a typical night's length of sleep/time in bed?
Hi Robysue,
Typical nights sleep before cpap has been around 7 hrs, due to working long hours, whilst away from home. I work 2 weeks away and a week at home.
When home my sleep is nothing short of erratic as i don't have to get up early. I try and spend time with the better half and she is a night owl, lol.
Since she is an invalid, i do everything around the house, though no real rush to get it done. End result is intermittant sleep pattern.

The sleep guy set it up for me and he knew i would not be back to see him for quite a while. No idea why the settings are the way they are.
I'm a total newb, so he could have done anything he wanted to, however i did a sleep test in hospital and they have all the results. Guess he based it on that info. Since then i have also done a home sleep test, so they have 2 lots of info to base settings on. No idea what my titrated pressure was.

But keep in mind that I'm one of those people who seems to be quite sensitive to even slightly too much pressure: My titrated pressure was 9cm and when my S9 was running as straight CPAP at 9cm I had some nasty problems with air getting forced into my stomach (aerophagia) and air getting forced into my eyes via my sinuses and tear ducts. It got bad enough where the PA in my sleep doctor's office ordered a week of auto-titration and then lowered my pressure to a range of 4--8. I think my upper limit may need to be raised (slightly) since the AHI's have crept up since then, but in my case I think it's going to be walking a very fine line between finding an upper limit that is high enough for the S9 to respond appropriately and low enough to not lead to the (for me intolerable) side effects of air in tummy and eyes.
Sounds like you had a bad time of it, with air going places it wasn't meant to. Hope it is all ok now. I doubt i will touch the settings at this stage, unless i seriously need it and then only when i'm out in the desert working, miles away from civilisation. As i could be going anytime and a fair chance i'll be without internet, i needed some info to get by with.
robysue wrote:So if you do decide to slowly increase your lower pressure limit, pay close attention to all of your body, not just the AHI. If your tummy and eyes can tolerate the additional constant pressure needed to reduce your AHI even further---great. If not, then you and your doctor will need to find a workable compromise for the pressure setting.
Good luck
To date, the S9 appears ok. It feels like there is some back pressure(?) when i breathe out. Perhaps the temp needs to be adjusted down a bit, from the 27C it is now.
He told me most people have it set on that number. See what happens when i'm away from home.
Thank you for the chat.
Regards
