obstruction persists with CPAP

I read this:

Optimal treatment options for mixed sleep apnea still need to be refined. Currently one of the best treatments is still CPAP devices, but set at the lowest possible pressure setting that successfully keep the airways free from obstructions, but don't allow CSA symptoms to develop.

Has anyone experienced such symptoms developing? I noticed obstruction when the air pressure is at its highest, but assumed the pressure increased when there was an obstruction (chicken or egg?). I need to find out more about the activities of the machine and how to regulate it. Woeful lack of guidance. I will try calling the machine company.

I am unable to change settings on my equipment myself. However, I am having issues that my pressure is not high enough to stop the obstruction all the time. They have raised it once, but still not good enough. They may raise it again, or they may make me go for another study.

In theory, you should have a sleep study then titration study and a doctor should discuss the results and then write a prescription based on the study results and your conversation. Doesn't happen that way often. The titration study is geared to assessing the amount of pressure needed to keep the airway open. Guess the prescription depends on the skill of your doctor in interpreting the results so things can go wrong in some cases. As a person's physiology changes, the need for a different prescription may change so another study may need to be done. I would also think that a person fumbling with their own pressure settings is more likely to do harm than good and at best be ineffective. I would also guess that if a doctor doesn't really prescribe properly, another doctor should be sought out and the doctor should be researched prior to any first meeting so that other patient feedback on this doctor could be assessed. Folks who believe their pressure should be changed should be careful about making this assumption as it may or may not be correct and should be discussed with this great doctor with great patient feedback and let this doctor make the call on pressure settings...
