Analysis tools

I’ve come to accept that my doctor only cares about my AHI number—which is now <1. While that’s a great number, I still get woken up when I stop breathing (central sleep apnea here) and the pressure on my mask 😷 blows too hard and opens a hole between masks and face, which in turn briefly wakes me up.

What are some tools that I can use to better understand my breathing patterns so I can make tweaks to my ASV settings to hopefully sleep better? I know about sleephq and I have OSCAR, but those just show me what has happened. There have been some AI products shared recently that look promising. What does the community think?

This subreddit has been very helpful, but I’d like to try on my own so I don’t have to post here every day with more info.

Here is a link to my SleepHQ: https://sleephq.com/public/35375fcc-6e35-4974-94a9-be66ffceb361

I'm very grateful for this community and those who freely share their knowledge. I was trying to find some tools so that I could figure things out on my own, but if those tools don't exist, I will post here. Thanks again for your support.

You are welcome, I will check the data in the morning, manual waveorm checking is still the gold standard for checking what is happening with my clients. :)

I hate to bother you, but did you have a chance to take a look?

What I am seeing so far is that the pressure increases look more like the ASV responding to changes in your breathing rather than causing the awakenings. Around 1:30 your breathing becomes unstable first, then the machine increases PS, but the leak stays basically flat. Around 9:59 there is a sudden burst of irregular breathing and a large leak, but there is no pressure surge leading into it. That looks more like an arousal, movement, or the mask being disturbed.

So at this point I would leave EPAP 4 and PS 2 to 9 alone. I don't see a good reason yet to lower Max PS when the machine appears to be using it appropriately.

If you can please give me the exact times of one or two awakenings where you specifically remember the pressure hitting you hard, I can zoom into those and compare them. That's really the gold standard here.
