AHI moderate - sleep too short - feel tired

RE: AHI moderate - sleep too short - feel tired
I found the valve here. But I don't know if it fits to my 15 mm hose. Corr-A-Flex hose is only available for 22 mm. Do I still need an adapter?

Today I had finally again AHI of 2. I hope that it was because of the beer.

Even though you use a 15 mm tube, the ends have 22 mm standard adapters.

Okay, thanks Sleeprider.

I didn't understand which silicone to use to close the openings?

If you want to make a temporary seal, use tape. For a permanent seal, use any silicone sealant. Any silicoe sealant should work fine, and the vinegar smell will go away when cured. If you want, you could try a "food grade silicone" or one from an aquarium supply.

RE: AHI moderate - sleep too short - feel tired
Sleeprider, I know you know a LOT more about the practical application of sleep apnea treatment than I do but I have two comments.

1) Thanks so much for the link to the EERS. I had not seen the previous posts about this idea. It makes so much sense. I spent a couple of years trying to optimize my pressure settings and the best I’ve been able to do is get my AHI down to about five with one of the five as obstructive and four as centrals. (I’m an R&D engineer so while frustrating this process was kind of fun too.) With an AHI of five I don’t believe I need to mess around with EERS but it’s fabulous to know about it in case things change.

2) Having spent so much time optimizing my pressure settings I am convinced that certainly daily, and really even weekly results, are not worth using for settings changes. There are things that affect AHI that are so variable, AHI results bounce around a lot, at least for me the centrals do. Over the course of a month my obstructives remain fairly stable but the centrals can go from one to ten. As I was reading through this post and saw perler242 was concerned about an AHI of eight for one night I was going to comment to leave it alone. One night is meaningless. I see he soon posted an AHI of two which would be consistent with my experience as well. So net, learning about EERS is fantastic but I believe perler242 is over-reacting to short-term changes and should wait at least a couple of weeks, and probably a month, before making any adjustments to see if there really is a trend beginning to form.

RE: AHI moderate - sleep too short - feel tired
Steve, I'm not very concerned about AHI and particularly CAI generally less than 2-3 unless there is a complaint about comfort or sleep quality. Most of the people experimenting with EERS are using it with AHI greater than 5, and as a means of avoiding ASV. It seems to work best for treatment emergent central apnea, rather than a complex or central apnea present prior to using positive pressure therapy. One of the unexpected benefits of the therapy is that it appears to produce a real benefit in tidal volume and minute vent.

This thread started with Perler using a Philips Auto CPAP with AHI generally above 5 and as high as 19 with a lot of hypopnea, flow limitation, and a fairly low tidal volume in the 380 range. Higher pressure resulted in greater sleep fragmentation and poorer quality of sleep. About Post #42 Perler switched to a Resmed Airsense 10 Autoset, and saw a reduction in hypopnea, and large swings in pressure in response to flow limitation. As we increased EPR, the flow limits dropped, but CA became more prevalent and tidal volume remained unimpressive http://www.apneaboard.com/forums/attachm...?aid=16324 . The first discussion of EERS was not until post #69 when this chart was posted with a CAI of 8 http://www.apneaboard.com/forums/attachm...?aid=17112 . That was just the day before yesterday, and we are in the early stages of experimenting to see if this might be a solution, however, the most conservative approach is to ignore the bad session and mark it up to the cold, continuing on course with what appears to be working.

So, I agree with you Steve, that aside for the night when Perler complained of a cold, his efficacy and comfort were both improving. I think EERS may help to stabilize the transient CA events, and for the most part the AHI is not a driving consideration, but if he wants to give it a try, I'm always curious to see if it produces a benefit. So I think that is where we are. This is a completely optional modification, and one that can be reversed easily, especially if the exhaust vent is taped for a temporary trial. I don't want to push EERS in this case, but I don't mind facilitating it.
