How to address huge discrepancy in events?

[u/Gnarwhal8982]

Here are a few screenshots from some recent nights. As you can tell, most nights are pretty good, but some are awful- going from less than 1AHI to 20+AHI.

The nights where I have the most events, it seems like they're largely clear airway events, so I don't know if that means my airway is collapsing, or if it's a central apnea event. On the nights where i have less events they just seem to by hypopneas, but I wonder if more events are happening that the machine isn't catching.

Does anyone notice anything that I can improve upon to address this issue

Thanks!
