I already know that if the memory card is out of the machine for a night only a bare minimum of data can be saved. In fact when I left the card out one night the machine said I had an AHI under 5 since no CAs could be recorded. I have already used my machine for more than 30 days straight so I am in compliance insurance wise. My plan is to use my own memory card and create a new profile on Sleepyhead. I can then see how my CAs respond to lower pressure. I plan to change the machine back to Bi-Pap and use an EPAP of 5 and IPAP of 9 to start with. These are the starting numbers for my ramp up at current settings. Does anyone have any comments or suggestions?

Lowering my PS from 4 to 2 reduced my CAs fairly dramatically.

RE: Central sleep apnea periodic breathing
I am getting a new ResMed Aircurve 10 Vauto to replace the one that I have now. My present machine has already been de-listed from the ResMed website. Tonight I plan to insert a newly formatted SD Card to collect the data from the machine. I plan to use my beginning ramp up settings of EPAP 5 and IPAP 9 as the pressure settings using Bi-PAP. No ramp up since these are the beginning ramp up settings. I hope to see a reduction in CAs. My hope is that I will see more normal breathing or at least more periodic breathing without apnea, I have an issue with HBP first thing in the AM and I even see a significant rise even after a 1 hour nap. I went for my sleep study because of the morning HBP and my wife's reporting that I seem to forget to breathe at night. I do have a periodic breathing issue even without CPAP. I may be a candidate for medication to control my periodic breathing CA issues. If I can reduce CAs while on the machine I can use the machine as a diagnostic tool to regulate medication.

RE: Central sleep apnea periodic breathing
Well, so much for lowering the pressure. Last night I had an AHI of 43. That is 7 higher than my worst number on APAP at higher pressures. My AHI during my sleep study was 44. It appears that the machine has some beneficial effect. It also shows that my CAs are not the result of higher machine pressures. I still cannot rule out that any pressure is worse than no pressure. Details: I set the machine to EPAP of 5 and IPAP of 9. No ramp up. Not sure what to try next. I have another day or so before my new machine arrives. Right now my present machine is in airplane mode with a different SD card. Any suggestions?

There is some theory that the pressure difference between IPAP and EPAP can cause CO2 washout. Tonight I am going to try straight CPAP of 9. May use a short ramp up.

RE: Central sleep apnea periodic breathing
Your solution is the ASV machine, I assume you are having delivered. There is not much you can do with the current equipment to deal with CA. I"m a little confused, it sounds like you are currently using an Aircurve Vauto, and are replacing it with the same. Why are you not getting the Aircurve 10 ASV or ST? Without a backup rate, I don't see how the CA are supposed to be resolved.

Doc isn't ready to go there yet. My guess is that I will end up with an ASV machine, medication or both. He still wants to rule out a faulty machine. I think my original sleep study was misread.

Well, certainly wish you best of luck, but trying the same thing and expecting a different outcome seems like a waste of time to me.

I'd agree with Sleeprider, who knows more than I.

Also, it's a 'long shot' that your study was misread AND your machine is faulty. Chances are 'pretty slim' for those two things happening.

I seriously doubt that the machine is faulty. I will find out in a couple of days.

So that may only leave your sleep study in question, but if your sleep study conformed to review procedures, the RAW data was reviewed by three professionals- your sleep technologist, a supervisory sleep technologist, and by a board-certified sleep doctor who supposedly writes a separate report with doc's findings.
