It's like there are no apneas at all some nights. (Just like the two sleep studies said. ) Don't I wish! I've seen a similar pattern a lot since switching to the Swift pillows interface. The night-to-night pattern can be seen in the next chart. I switched to the Swift on February 28 (I think). A week ago, there were even four days in a row with no real pressure increases from the APAP all night.
When I first saw this pattern I thought maybe it was related to reflux being under better control, but if that were true then you'd think there would be a gradual tapering off over the past two months as the Protonix took effect. But, that pattern is just not there. Also, peak pressures stay about the same over this entire period as can be seen in the following chart from a few nights ago. The APAP was working about as hard that night to control apneas as any night since I started xPAP.
The only variable which seems to correlate with this new pattern of few apneas is the fact that I changed to the Swift interface and in doing that my sleeping position changed slightly to accommodate the Swift. I normally sleep on my side, but with the Swift I don't have my head fully on the pillow, otherwise the pillow ends up causing interference to the Swift which then leaks. Instead, only the back of my head is on the pillow which leaves my lower face and jaw unsupported. (I've posted here before on how my apnea is correlated with jaw position.)
I'm not quite sure what to do about any of this yet, which is part of the reason I'm posting this now. (The other reason being that writing all this down helps me think more clearly.) What I'm thinking now is that my current pillows need to change. (Maybe a big block of wood would be good. )
Suggestions?
