AHI moderate - sleep too short - feel tired

It's interesting that CA events more closely correlate to periods of higher oxygen saturation. It always appeared to me you could tolerate lower pressures without increased events, and the EPR was there to help with flow limitation. The flow limits are less important than your good sleep, so low pressure and low EPR seems to be working fine. You don't have a need for obstructive sleep apnea therapy at higher pressures, and you certainly would not tolerate pressure fluctuations by ASV. In time you should consider evaluating oxygen saturation and simply treating that separately as an adjunct to CPAP therapy if indicated by your doctor. Adding an oxygen bleed to your CPAP therapy is an easy thing to do if you need it. http://www.apneaboard.com/wiki/index.php..._with_CPAP
