I finally got the results of my sleep study. Well, partial results, anyway. In-home tests can find either obstructive or central apnea, and complex apneas appear as obstructive. So, unsurprisingly, it determined that I have obstructive apnea.
Anyway, the good news about this (and it’s all good news!) is that I’ll be getting a CPAP machine, and modern CPAP machines are small, lightweight, self-adjusting (no need for a separate titration!), and also provide ongoing diagnosis. So after two weeks of sleeping with it, I’ll know if I have complex or simple obstructive apnea, and either way the treatment is a CPAP so I don’t really care to split hairs about what the underlying problem is.
