I notice a lot more central apneas when I am struggling to fall or asleep, or when I am laying awake after awakening. The bottom line is, you have to look at the AHI and see what the breakdown is, particularly the type of events that are occurring and when are they occurring. Central apneas occuring during wakefulness are probably of little concern, since it is unlikely they are going to be accompanied by hypoxemia.

Central apneas occuring during wakefulness are probably of little concern, since it is unlikely they are going to be accompanied by hypoxemia. I find a very similar thing here too. CSA/CA happens often when I am falling asleep or just waking up, but not fully awake yet. In addition, I find CA happens when awake when I am concentrating and focused intensely on some problem or task when sitting at the desk. If I read something that requires focus, I soon realize I am getting light-headed and need to breathe. It starts out as shallow breathing and then slows to a stop. It's quite a strange thing, this CA. You would think the brain, being an oxygen hog, would be more a dictator and demand with an iron fist that the lungs keep working... I wonder what is behind CA in a wakeful state? I can start breathing full breaths for 30 seconds, then as soon as I go on to something else, the breathing falls way off. During excercise, breathing is heavy and normal without thinking about it. Tom

Bear in mind that the brain consumes more energy when you are thinking hard, and the brain burns only glucose. It is quite common for people to become temporarily hypoglycemic when thinking hard. In fact, one of the symptoms of hypoglycemia is irrritability. Have you ever interrupted someone lost in thought while working on a difficult question? Did they snap at you? It was not their personality; it was hypoglycemia. I'm not saying that this is what happens to you. I am merely pointing out that becoming lightheaded while working on a difficult problem may be caused by hypoglycemia rather than anoxia.

Same thing just happened to me. Trial S8 Autoset had me at AHI of 3.7. First night on S9 Autoset had me at .9.

CPAP machines vary greatly in how quickly and accurately they adjust pressure in respect to apneas.
S9 AutoSet in particular seems to detect the precursors to actual apnea and react before they happen. It's also been speculated that S9 records a lot fewer apneas, even at the same pressure. The belief seems to be that it's less harsh on judging borderline apnea events. Or that it's smarter somehow and avoids false alarms.
