Sleepless in Seattle

RE: Sleepless in Seattle
I would roll with the current settings for at least 3 more nights, and see how it turns out.  It was quite interesting that the CA events reduced as changes usually result in slight increase for a couple days.

Can you also re-post Jul 10 and Jul 9 with these new screen settings?

I noticed that RERA is much higher with adjustment to CFlex = 3, and would be interesting to see if these subside.  These are real arousals that are due to respiration efforts.  It is no wonder that night felt like a beating.

I'll get those other dates up with the new Y axis. Just thought of one other thing! I turned the humidifier of last night in the provider screen. I left the humidifier tank attached but it was empty and dry. Could this have effected the machine functionality? I remember reading something that if you choose not to humidify that you should detach the unit and use the direct plug into the DreamStation primary unit.

Not sure if this might have an effect but it sure is interesting how high my AHI spiked and like you noticed not many CA events at all mostly other events.

RE: Sleepless in Seattle
Hello all,

Fast update. My AHI had been stable under 1 for several weeks and I was feeling good each morning. The last week or ten days it has gone up to around two and I feel less rested. No changes to any settings, gear or environment. I'm also having RERA and flow limits so the RDI is even higher. My doctor feels a fixed pressure is what I need and I'm thinking of giving this a try.

Should I stay in Auto and just set min max the same or go to CPAP mode. If I switch modes what effect will CFlex+ have? Is it similar to Aflex? I tried Cflex one night and actually like the feel better but my AHI was way higher almost 4 compaired to less than one at the time.

Any suggestions would be great. I'm getting there with some ups and downs.

Hello all,

Here is an update. As some may have read from other threads I have been adjusting my pressures in search of a better night sleep. I had been on a fixed setting of 9 with Aflex 1 but have changed to 8.5 fixed with no flex of any kind.  These screen shots are of a typical night with both of these setups. Not a bad AHI but I never really feel rested.

These are for the 9 fixed with Aflex 1.

Full night.

I had better AHI consistency with 9 fixed and Flex1 than with 8.5 fixed no flex. I have had a few nights with 8.5 no flex that were miraculous night sleeps which never occurred at the former settings. I have issues with Aerophagia which have been helped with the lower pressure and I think turning flex off. I have tried fixed no flex at 9 but blow up like a balloon. I have been playing with a sleep tracker and have found that my amount of time in REM and deep sleep have been trending upward with the lower pressure and no flex but at this point these findings are far from scientific.

Can anyone find anything interesting with my screen shots that might provide a clew as to which way I might go? Any help is always most appreciated.

Walla Walla,

Thanks for the input. I know I'm close and might actually be near my best but still appreciate a second set of eyes.

I've been experimenting with BIPAP in an attempt to help with Aerophagia. I initially set the Resmed S10 Vauto to about the same settings as I was using on the DreamStation.

9.5 fixed Aflex 1

This provided an IPAP of 9.5 and a sort of EPAP of 8.0 for me with my breathing pattern.

on the Resmed I set:

IPAP 9.6
EPAP 8.0

Trigger: High
Cycle:    Low
TiMax:   2.3
TiMin:      .3
EasyBreath: On

These were after experimenting for comfort. There is nothing scientific about my choice.

Great results numbers wise with zero AHI where the DreamStation was consistently 1.75 no difference with Aerophagia and still flat inhale tops on the flow wave chart. Last night I started to bump things around and raise IPAP to 10.0 everything else the same. Good news no increase in Aerophagia and still low AHI of Around .7 A few CA but they were also just after a series of large breaths so may have been after a momentary awakening.

Strange news, in the attached screen shot which is zoomed in I have picked up a small bump right at the zero line at the end of exhalation. I think I can actually feel this when awake but not sure if it correlates. Additionally, with the DreamStation my I:E ratio was inverted (Longer Inhale than Exhale) but with the Resmed it is now correct but seems large. I have read some other threads on here, Thanks Sleepster Walla Walla OpalRose and all the others, talking about some people doing better with the Resmed algo Vs. the DreamStation Aflex and I might be one of those.

Before I make additional changes I wanted to get some feedback on the anomaly if it is one that I have circled in the attachment. Maybe some suggestions and the other settings as well. My plan is to start decreasing EPAP when stable on my current settings to reduce the Aerophagia. Supplier #1 had an interesting article on using this technique recently to help with Aerophagia so I brought it up with my sleep doc. He's on board so I decided to give it a try. I have also felt that I've needed more IPAP but could never do this with the DreamStation.

Any thoughts would be greatly appreciated.

Don't know what the bump is I'm not an expert of the flow charts. . The good news is your respiratory numbers look great and your breathing well.

RE: Sleepless in Seattle
For my aerophagia I tried an incline pillow, or you can just pile up two pillows, or double up one pillow. Enough that your head is somewhat raised. I forget exactly what it does, but that was all I needed to eliminate the horrible cramping. For travel, I just double up on pillows. Hotels seem to love putting out enough pillows for an army anymore, so there is usually an excess of them. It might be all you need for aerophagia.
