My recommended titration pressure was 11.0 cm. of CPAP therapy. I have successfully made it to the clinician's menu, and after many changes, have my AHI down to 2.5-2.9. My sub conscience has been telling me though that something still is not quite right. I have been running the machine in auto mode, and it's coming back with pressure readings around 12.0. Last night I might have made a discovery though. I woke around 3:00 am, and saw my mask was off and my brain was mad. I reached over to the machine, and changed it to CPAP mode which I had preset for action. I reengaged operation, fell asleep, and finally went to CPAP heaven for the first time. Does anyone have any thoughts or ideas about this experience that may make me less dangerous?
Welcome to the forum. There are lots of people here that are willing to share their experiences, and hopefully answer your questions.
What was the pressure range you were using while in Auto mode?
(1) Download and setup SleepyHead. Many users prefer it for looking at the graphs, and that will be crucial while you are trying to dial in your treatment. The testing version 0.9.8 seems to be quite good so far for me. There is a link at the top of all forum pages.
(2) Some folk do better with a fixed pressure, others adapt well to the Auto mode. I use Auto mode with a fairly wide range, but my pressures usually stay between 10 and 14. Your body's reaction to these modes can only be determined by experience.
(3) Make any changes to your treatment slowly. Change one thing at a time, and allow at least a week to evaluate each change. The temptation is to look at everything and react on a night-by-night basis, but treatment has too much variation - you must look for trends, not a single night's numbers.
(4) Initially, the things to watch are Leak, Pressure, and AHI. If there is too much time with "large" leaks (for ResMed S9's the limit is 24 l/min), then Apnea events may not be controlled, or even counted correctly. Obviously, the higher the pressure, the more difficult it is to control Leak.
(5) If your sleep study showed primarily Obstructive apneas, then you may find that your condition is position-sensitive. For many people with Obstructive Sleep Apnea (OSA), their apnea is worse while sleeping on their back. In my case, the Apnea index was nearly 20 times worse while on my back. I have found ways to avoid back-sleeping for the most part, and the pressures and AHI are much lower because of that.
Let us know as much as you can about what is happening for you, and we'll do our best to help.
Good luck on your journey.
