The machine did the titration, just as Destin's has done. With the support of another forum, I learned to read and interpret the data and narrow the range of pressure to optimally treat my problem.
Destin, good for you getting this far. Your data do show the machine is working in auto mode to treat apnea events, and you are being treated at inhalation pressure ranging from 7 to 14.5 cmH2O, and have an exhale pressure relieve of 4 cmH2O. It looks like you could have been treated with an Autoset machine, but this seems to be working fine...especially if you feel good. Keep going and I'm sure you'll get lots of support here as you post results of data. If you have questions of what that data is showing you, ask. Looks like you're doing great.
Welcome to the forum! Thanks for contributing to this thread!
Your choice of machine was perhaps more than needed, but excellent all the same.
ResMed has said the S9 VPAP Auto was their optimal machine to treat Obstructive Sleep Apnea (simple OSA uncomplicated by Central Sleep Apnea).
In my view, the summary data you posted indicate you do not have any significant amount of Central Sleep Apnea and the machine will be completely sufficient to treat your OSA. So, in my view, there is no need to have an in-lab or in-home sleep test unless required by a family doctor or sleep doctor before providing you with a prescription for the machine you already have (any medical doctor, not just a specialized sleep doctor, can provide the prescription) or unless treatment with your machine still leaves you with disrupted sleep and daytime fatigue, etc.
As Archangle has posted, a primary benefit of an in-lab overnight sleep study would be to find out what else is wrong, in case more besides Obstructive Sleep Apnea needs to be addressed. I think an in-home study provides much less data and I don't know how necessary or valuable it may be to you at this point.
I think an in-lab or in-home sleep test is unlikely to find anything more than simple OSA (it usually doesn't), but this doesn't mean it would be a waste of money, any more than having paid for Term Life Insurance last year would have been a waste of money since you didn't die last year. If you can afford it, it is appropriate and wise to have Life Insurance which will provide for your family when you no longer can, and having a Sleep Test may help save your life if it uncovers another condition needing attention. Is having a sleep test medically necessary, even if you have no insurance and the cost would be destructive? I think not, but only you and your doctor can make that decision.
At the very least, I suggest working with a family physician or sleep doctor (neurologist, usually) to obtain a prescription for your current machine.
In particular, I wouldn't get an in-home sleep test unless your doctor would require it (some doctors may simply accept the evidence provided by your current machine), and in any case I would research what sort of conditions the particular in-home sleep test would be able to diagnose. If the test results would not be able to do more than detect and distinguish between obstructive versus central sleep apnea, I wouldn't see any added value to having the in-home sleep test, since your machine already does that. If it would be able to detect heartbeat irregularities like Atrial Fibrillation then it may be valuable, but a basic cardiology "Holter monitor" test may do that better and more economically.
A danger which may be created by spending an unaffordable amount on an optional sleep test is that it may "croud out" spending on more important testing and treatment. For example, the money may be better spent to see a cardiologist and have basic tests taken to see if previously-untreated OSA has caused you to develop Atrial Fibrillation or some other condition which may need immediate treatment, such as blood thinners to prevent stroke, or high blood pressure meds or whatever.
