I learned a lot from this excellent video by Jason:

Based on that video, the great majority of the CAs I'm seeing in my SleepyHead data aren't real CAs. But it's a pain in the rear to go one by one looking at all the events and manually adjusting my CA index for those.

Which leads me to wonder - is it safe to basically ignore the ones under 15 seconds or some other specified cutoff? I'm assuming it isn't normal to wake, yawn, and stop breathing for a minute. And there must be some duration which tends to be more likely to cause hypoxemia.

Thanks! Happy to hear that.

Not really. Legitimate CSA can be in that same range of 10-15 seconds....which I would say is the most common duration. Much longer than this I would say is more likely to be legitimate though. This is just playing percentages though. There really is no shortcut other than taking them on a case by case basis.
