Help with Sleepyhead Results - High CA Events After 6 Months

I have been using CPAP for about 6 months and need some help with stats and help with where to go next. Diagnosed with AHI of 13, doc gave wide open script of 4-20 without titration. Pushed minimum up to 7 to breathe and I am comfortable wearing the F&P Simplus with minimal leaks after a lot of trial and error with nasal pillows and tons of leaks. My issue is that I am still waking up 5-10 times a night and have a really high amount of Clear Airway events. I thought that the waking up frequently likely drove the CA events due to irregular breathing at that time - but the few times I do not wake up more than a few times at night - there is no decrease in CA events. My sleep study indicated no central events. Is there anyway I can improve my therapy or am I at the end of the line? So far it has helped, but I feel like I could really improve it if I got a push in the right direction.




Thank you in advance.

I should also add that I do at least 15-30 minutes a day of vigorous exercise and lay off caffeine after 3pm. I feel much better now that I use CPAP, but maybe the machine is what is now waking me up. Maybe I should narrow the script?

Welcome to the board. Please be patient for responses to your question.

Have you tried a much smaller apap range or even cpap mode pressures?

Those centrals could still be post arousal centrals or even sleep onset centrals for when you go back to sleep after an arousal.
Remember we don't always remember all our arousals.

If it were me I would still try to fix or improve upon the arousals/awakenings and see what happens to those centrals at that time.
On the chance that the centrals are related to higher pressure (but there are times shown with centrals and the pressure is low) you might limit that maximum a little and increase the minimum. Tighten the range a bit or even a lot and see if the changing pressures is contributing to the lack of optimal sleep quality.
I don't think this is CompSA going on here...but it wouldn't be totally impossible for it to be CompSA. If it is, it's really mild because the central index isn't horribly high.

Pugsy, thanks for the reply. I will try to tighten the range and see if I get better results. If that doesn't work, I'll try straight CPAP mode and see if I am just generally sensitive to any pressure changes. Thanks again.

Puny,

Zoom out on the CA's. Often Sleepyhead reports them, but they are not valid (you're awake) or doing something else going on.

This is a good nights sleep for me, but sleep study did show CA's occur.
