Jen,
Central apneas can be caused by obstructive apnea, but you can't know that without a well done sleep study (it would show central apneas following obstructive hypopneas or apneas).
Central sleep apnea is this: The brain failing to trigger the body to breathe for one of two reasons:
1. The brain perceives some danger of aspiration and instructs the body to pause its routine breathing so as to allow the danger to pass. The "perceived danger" can be reflux, large tonsils or adenoids, or even a large tongue or one that falls back into the throat during sleep. In these cases, removing whatever the "danger" is, will often remove the bulk of central sleep apneas.
2. The brain actually falls asleep and forgets to tell the body to breathe until the CO2 level reaches a level that acts almost like an alarm clock to wake it back up and take a breath. There are numerous options for treatment of this form, none of which involve surgery.
I guess my previous statement isn't entirely accurate, because if the centrals are being caused by the obstructives, then the removal of the tonsils/adenoids would indirectly remedy the central apnea, too...
