AHI: 0.5

CA: 0.4
Leak is always <12 L/min @ ~15 cm H2O.
My concern is with the frequent CA's being nearly 50% of my apneas (if I'm reading that right) on a lot of nights.
When I was diagnosed in 2009, I was told it was strictly obstructive apnea. I'm wondering if changed, or if the S9 is reporting CA's for some other reason. .
it's reporting 'em because you're having them... it's fairly normal for people to have them occasionally, for instance, when going to sleep, or waking up, as your body switches from awake to asleep breathing, you may hold your breath for a bit... tada, a central or two... it's referred to as swj, or sleep/wake junk.
in a study, they've got EEG traces and can see "oh, patient isn't asleep yet, so this doesn't count towards the AHI" your machine, not being wired to your head, doesn't have that insight, it just sees you stop breathing for a few, and determines your throat isn't closed.... ergo, it says CENTRAL! *ding*.
no matter what, an average of .4 per hour over the night is insignificant. the percentage of total apnea is pretty meaningless.
