Air Flow Interruption
I've been a happy CPAP user until recently when I've had to transition to an ASV machine, and it IS magical! Meanwhile, several times over the years I've asked friends and apnea professionals alike what--to me--is the major question and problem behind all sleep apnea treatments and have not gotten an understandable reply. Now I'll ask you all! 
Since correcting the problem of having sleep apnea is centered on overcoming interruptions of oxygen getting to the brain, our therapy machines seek to surmount whatever obstacles there are. None of them, however, totally prevent air flow interruptions (unless I'm sadly mistaken).
So. Have I got this right?
-CPAP machines minimize interruptions of the flow of oxygen to the brain.
-BiPAP (and their variations) machines are a little better than straight CPAP machines at minimizing interruptions of the flow of oxygen to the brain.
-ASV machines are about the same as BiPAP machines at minimizing the interruptions, but since they pattern seek and intervene, they greatly reduce AHIs and thus eliminate most of the interruptions to the flow of oxygen to the brain.
