3 months with CPAP and still choking (charts included)

I can try adding 2 minute zoom in previews again.
Is there a specific time period that you need to look at?

Also is there a setting to set dotted line at zero?

To set the Zero Flow Limit line, go to the Daily screen, right-click on the Flow Limit word in the graph, Select the Dotted Lines (last option), the select Zero (again, the last option).

It'd be helpful if you provided one or two 2-minute zooms during the time you felt you were choking.

For what it's worth, there can be so-called silent reflux, where burning sensations and such are absent. Google it and you'll see lots of information. The pdf available from the NHS in the UK specifically mentions "choking episodes, especially at night" as among the possible symptoms.

One change to try making right away is to avoid lying down within 3 hours of eating. This is generally recommended for better sleep, and it is very important for people with reflux.

Try increasing your pressure to 8.  We want to see details of the choking issue.

Adding 2 minute zooms where I think choking could happen

Good to know about silent reflux.
I will check with doctor if that's indeed the case.

Earthless, sorry, but I can't see the zooms. Can you post them as screenshots?

[earthless]

Sorry I can't do more attachments because of attachment quota.
Once you're on imgur page click on the image to zoom in.

[Dormeo]

For me, that imgur isn’t clickable.

Now that my attachment usage was raised I'm adding more OSCAR charts here

Thanks, earthless. In each of those zoomed-in views, I think I'm seeing some arousal breathing, followed by one or two events, followed by a resumption of regular breathing that is typical of sleep.

You mentioned you felt you almost choked to death; do you think you were awake for a while after that? If so, I'm wondering whether the choking feeling happened at some other time during the night.
