Yes I use Sleepyhead. What I have seen there as well as when roughly correlating sleep data from my Fitbit is that, as I may have noted as part of another earlier post, the CAs seem to arise, sometimes in clusters, at sleep transition points. This is especially true at the very front end and final back end of a nights sleep and also especially if I get up to use the bathroom during the night. There seems to be a stuttering handoff between waking breathing control and the neuro-chemical side of sleeping control. Does that make any sense and/or have you seen this?
I have been on therapy for about 10 months using a Resmed Airsense 10 Autoset.
I seem to have my setup tweaked to all but eliminate obstructive events but I am seeing a slight increase in Centrals, Hypopneas and RERAs after previously reaching a point where I was regularly getting overall AHIs at 1.x or less. I've read where this sometimes occurs after several months of therapy.
I'm not talking huge numbers here. My AHI last night was 1.9. For the week (with a couple of poorer nights) I'm sitting at an average of 2.4 consisting of 1.3 CA, 0.3 O and 0.8 H; and for the past month an average AHI of 1.5 consisting of 0.6 CA, 0.3 O and 0.6 H.
My pressure range is currently set, thru a number of trials, at 7.0 - 10.0. I quit using the evaporator months ago and found I got better results. Same with turning off EPR.
Any suggestions on how to keep the CAs and Hs in check?
Update: Practiced with the Mini some more at home and then made a 5 day trip with it. Achieved quite satisfactory results. Apparently just took some practice.
I've been running some practice nights on and off with my mini prior to a trip later this week.
Just can't seem to achieve the same results and not sure why. I understand the mini is less sophisticated and not intended for anything other than short term use but disappointed just the same.
Part of the issue may be the ResMed P10 mask v my normal F&P Brevida. The former just doesn't work as well for me as the latter. I did end up changing the P10 pillow to the L size (use M on the F&P) and that seems to have helped a bit but was wondering if there were any other suggestions out there.
I really wish there were more mask options for the Mini.
Sleepbandit, what is a "tap appliance"?
BTW Sierra, I recently took your recommendation to try turning of EPR completely. I got immediate improvement in AHI and a reduction in central events. So far so good.
Your neurologist's comment regarding entral sleep apneas and sleep transitions is interesting as that is what I believed I was seeing in my data.
I hear you on that last point. I got so fed up with BCBS and their exhausting rules, misinformation and manifest incompetence that I finally just bought my own machine direct from Lofta and freed myself from the tyrrany of a crappy insurance provider.
