PAP not effective for central apneas?

I need to shut off my computer.

In response to a question I had in another thread, someone pasted in some info. from Respironics site about how the REMstar Autos respond to events (thank you so much BTW, even though I didn't understand a lot of it, it's good to have the info.) and one line has me completely confused.....

The reason for this increase in pressure followed by a decrease in pressure when an apnea/hypopnea is not responsive is to allow the device to respond appropriately to an event that is not treatable by increases in pressure, such as a central apnea.

My doctor just told me a few days ago that most of my events were CA's in my study. So is this saying that PAP is not treating my central apneas? Or is the pressure supposed to prevent the CA's from happening to begin with?

I know, I need to just go with it and let the results do the talking. I overthink everything these days!!

I would definitely inquire with your doctor to see whether a RemStar Auto is really what he/she wanted for you.

The RemStar Auto that you show in your profile is really targeted for obstructive sleep apnea, and not central sleep apnea. There may be a mix-up somewhere. We have had posters who accidentally received the wrong machine. Another possibility is that your doctor didn't quite convey the information in a clear way. Perhaps you had mostly central apneas during the PSG until your body became accustomed to CPAP pressure. But definitely ask.

I would also try to find out exactly what kind of AI and HI numbers your RT is retrieving via modem. I couldn't find that information in any of your past posts. Post at least a brief summary of your RemStar sleep data here so that experienced members can either put your mind at ease or suggest that you raise issue with your doctor if the numbers are too high.

Yes,I would also ask to have the sleep study results in writing.

I'm getting confused as to what you're doing with your pressure settings. (in your M Series Auto)
A little over a week ago, you informed me that you had gotten an AHI of 0.9 with some pressure settings you had (I believe you had the minimum at 8.5 in Auto mode). Now in another post this afternoon, you mentioned a pressure range of 10 - 18. An AHI of 0.9 is not indicative of Central Apneas occurring at the pressures you were using......even though I believe I recommended you trying CPAP mode at a pressure of 9.

If you DID have Central apneas in your sleep study, you'd want to avoid wide open (and higher) pressure settings and in particular, settings much over 10 cm.

Has something changed significantly in the last week?
