Both OA's and CA's Significantly Reduced, but AHI still far above 5. Tips? - ooye - 07-21-2023
I was diagnosed in mid-June of this year after a Lofta Sleep Study. I had 65 obstructive events an hour and 29 central events an hour. The doctor recommended the AirCurve 10 VAuto Bilevel device, which I've been using for about three weeks. It hasn't been too much trouble getting used to, and I've settled into a fairly consistent AHI pattern. I've attached a screenshot of my OSCAR data from last night, which is fairly representative of my data each night. As you can see, my obstructive events are way down (under five!) and my central events make up the majority of my overall events, but they're down significantly as well. Given the fact that the BiPap is primarily used to treat obstructive events, but it also seems to be making somewhat of an impact on my centrals, is there much else to hope for besides getting my obstructive events down even further? Is getting all events under five possible with this machine?

There are 2 things you can look at. First You are having some of positional apnea. Positional apnea can NOT be controlled by pressure changes. You have to find out what position you are getting into and cutting off your own airway. Have you changed your sleep position? Sleeping on your back? Using more (or new) pillows? These things can cause positional apnea by chin dropping to your sternum and cutting your airway. Think of it of a kinked hose – nothing can get through – you have to unkink the hose…
IF you can’t make a simple change like changing to a flatter pillow helps then you will need a collar. I have a link to collars in my signature at the bottom of the page. It shows people who are not wearing a collar and the SAME person wearing a collar. There is a huge difference between the two.
Positional Apnea is showing grouped O or H apnea.
You can change your trigger setting to high or very high. I did that and it helped my central a great deal but I had no where near as many as you do. That is in the clinical setting.
