THE ROAD TO SUCCESS...almost there, help fine tuning please!

THE ROAD TO SUCCESS...almost there, help fine tuning please!
Following on from my earlier post http://www.apneaboard.com/forums/Thread-...ly-stopped, I think I am now finally heading in the right direction.

So, now I am looking for help to decide where to next.

My goal is to 
a) have AHI of less than 2 or even less than 1.
b) minimise leaks: (pretty much taken care of)
c) avoid recurrence of the side effects in my previous post: (avoid EPR of 2 or less and avoid undertreatment with too low pressures.)
d) achieve restful restorative sleep: still need to get there.

My "numbers" are generally very good but I still feel there is some way to go. 

I am still waking up during the night for no reason that I can see: not related to leaks/events.

I am still concerned about my flow limitations. I suspect these are my limiting factor, certainly associated with sudden spikes in FL or when my pressures Max out.

I am not feeling as refreshed as I used to when I started PAP therapy. Perhaps I am sleeping deeper and therapy needs changing. Certainly in the last few weeks I have been nodding off during the day, or in the evening while watching DVDs.

When I choose to not use the Nonin Oximeter I tend to sleep deeper (less disruption with the Oximeter lead getting tangled).

So I have now moved back to FFM and have settled on F30i Small Wide or Dreamwear Large.

I have largely chosen the For Her setting because this responds sooner, if a little gentler, and holds the pressures for longer. It lowers the 95% FLs somewhat, but there are still high max FLs and I am keen to tackle both of these.

I have gotten used to MinPress 9.4, initially this gave me aerophagia, but am adapting to this, and anyway I would rather have that than my other symptoms.

Still need to find that perfect pillow.....

My thoughts going forward are:

1. Back to APAP/Autoset, but with different settings, or try Soft Mode.

2. Dare I even try CPAP, say 10 with EPR3. I hesitate to do this because of this limits max pressure which caused my grief in the first place, prevents machine responding to FLs, maxes out the pressure and leads to HA and RERA.

3. Increase Min Pressure even more?

4. Find a way to increase PS?

Any ideas and input would be appreciated.

Here are my charts from the last few nights, generally representative of the last month.

RE: THE ROAD TO SUCCESS...almost there, help fine tuning please!
And here is my recent overview: 

   

the vertical red line is when I was hospitalised with chest pain etc. Came out of hospital, dumped the P30i and after that changed to FFM with higher pressures and EPR 3.

I note the gradual increase in FL, RERAs and AHIs.

I am wondering if this is as good as it gets with my Airsense 10?

Can I improve the FLs with this machine? I think I know the answer but would appreciate 2nd or 3rd opinions.

Thanks!

I think it may be helpful to zoom in on the respiratory flow rate chart at a 2-3 minute zoom level. I'm curious why it looks unbalanced and "hairy" at times, and punctuated with large spikes in flow. I would typically suspect flow limitation and perhaps leg movement, especially since you have had some issues with leg pain recently. I think we should focus on those two possible issues as suspects in arousal.

RE: THE ROAD TO SUCCESS...almost there, help fine tuning please!
I'm sure someone with more expertise than I will come along but I don't see any changes to take.  Your EPR is at 3, it is as high as you can go and that is what seems to help with the flow limitations.  And the flow limitations are the most pronounced event that you have.  Have you tried other settings like regular instead of for her setting?

The only other thing is a VAUTO which gives you more PS.  It will go up to 25ps which is like EPR in the bpap.  That is a lot of money for one without a good reason to think it would work.  sorry that is all I got - like I said, I hope someone will be able to make a more and better informed answer for you.

Thanks SleepRider:

I have zoomed into 3 of the areas of concern of the 25th December for comments.

this is on For Her, 9.4 - 13.0 EPR 3 with F30i.

Do note I am using a SCC full time.

CloseUp1 at around 05:45.
   

CloseUp2 at around 05:49
   

CloseUp3 at around 23:30.
   

for interest my limb movement index for the diagnostic study and the titration were low, < 3, does that help?

Hi Stacey

Yes, since I am on the F30i I have tried both the Autoset/APAP only, Autoset For Her. 

Here are some closeups of some trouble spots from the 26th when I was on APAP, (not the For Her)

HA1
   

HA and OSA
   

RERA1
   



Next thing I will do is try the Soft Mode for a few nights and see how this goes.

(Becker44a has found this to be useful 
http://www.apneaboard.com/forums/Thread-...rapy-Modes
and I last used this with the P30i which I have now discontinued.)

thanks for the reply.

All of the events in your charts above show a rapidly increasing obstructive flow limitation leading to either OA or H events, and any of these can result in arousal as well. I had not expected to see a positional pattern, but it is certainly there, and these clusters of obstruction are most likely the result of chin-tucking from your sleep position. Another problem is that with the For-Her mode, your machine is not responding appropriately to the obstruction when pressure is at 12 or higher. I recommend you move to Autoset Standard, and increase max pressure to 15.

Take a look at the positional apnea wiki http://www.apneaboard.com/wiki/index.php...onal_Apnea You are repeatedly experiencing a chin-tuck or similar positional problem, and it clears after an arousal and repeats. We have found this pattern can be disrupted using a soft cervical collar http://www.apneaboard.com/wiki/index.php...cal_Collar Think about your sleep position, pillows and other factors that might be contributing to this pattern.

In some cases, your arousals/disturbances/blockages are concurrent with leaks.  The leaks aren't large, but who's to say you aren't sensitive to them when they DO OCCUR?  they look like they are innocuous, and that they would not bother the majority of us, certainly not well into our history of PAP usage.

If you look at your leak charts, you have few of them, but you do have the odd one.  Why do you also experience a disturbance in your sleep of some kind, whether holding your breath, taking a deep breath, or actually stopping to breathe?  If you aren't actually closing off or pinching and narrowing your airway, and causing arousals or hypopneas, maybe the way you relax fully is to deform or to deflect your mask, and that brings on a leak large enough to arouse you.

I'm must swinging in the dark here, hoping I hit something...anything that won't break me hand.  Too-funny
Contrite, and wiser.

RE: THE ROAD TO SUCCESS...almost there, help fine tuning please!
@ Sleeprider, many thanks for the reply, very helpful, indeed.

1. on the issue of neck collars, yes I have been using this for months now. Indispensable. ATM I am just using the cheap and nasty ones from the local pharmacy but may need to import some better ones from the USA.

Also, I am looking to find the best combination of pillow and SCC.
A flat pillow keeps the neck more extended, which keeps the airway open and leads to more CA,  but my Medium size collar allows some jaw escape from the FFM. When I bunch up the pillow on its side, the SCC snugs up against my chin, and the jaw escape no longer happens. But I can feel my soft palate closing off a bit.

So now I have a slight thicker pillow, still soft. Why soft? because I have a thin neck and the SCC overlaps at the back and bunches up against the base of the skull, really uncomfortable. Still want tackle that with the wife's sewing kit.

2. Yes! The For Her mode. I did read something about the 12 cm H20 limit but never registered the practical application of this! I had this on my list to ask the sleep tech, too many other questions, but I think you have hit the nail on the head there. I will go back and look what happened in the past few months with the For Her mode when the pressures go to 12 or so. I will abandon the For Her mode for now.

I am trialling the Autoset Soft Mode for now, to see what that does for my FL, and my pressures.

Will keep you posted.

@mesenteria.

I don't discount this at all. when I used the P30i the mouth leaks drove me crazy and certainly led to disrupted sleep even with a complex arrangement of partial mouth taping. So far, I cannot cope with full mouth taping.

so yes maybe the leaks are still disturbing my sleep, I am getting used the little leaks from the FFM. Leak rates of 6 - 8L/min don't worry me anymore, perhaps as I get used to them I will be aroused by them even less. 

Swinging in the dark is always fun and can lead to surprises, I do like the lateral thinking. Just look after those hands!
