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.
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.
