The sleep study tells us that there is reasonable certainty that the events you are having on CPAP are unlikely to be obstructive. You only had two obstructive apnea, both while on your back. With the titration study you had, the clinic identified the pressure that produced the lowest number of obstructive events. It would still be interesting to see what kind of results they recorded, and whether the study actually mitigated your overall apnea.
I would conclude from what I am seeing in your sleep study, and the ambiguous results in the form of AHI events on your CPAP, that therapy has not been beneficial to this point. Treatment that actually produces worse results than baseline is not something I would continue. It will be important to observe whether a trend begins that points to improvement or not. From what has been discussed so far, your AHI has approximately doubled from baseline, and it is nearly certain that those events will be shown to be central or mixed in nature. CPAP can help in some cases of central apnea. but the data becomes more important to see at what point obstructive events give way to central. The difference of 0.5 cm pressure can make all the difference in the world. For most patients the use of ASV becomes more beneficial since CPAP cannot provide the stimulus to breath during central events.
