Mark,

I just found this "Awakenings": electrocardiographic findings in central sleep apnea.
http://www.ncbi.nlm.nih.gov/pubmed/20946562.

Nice to know I'm in good company. I'm thinking on getting a Zeo myself to check sleep stage. I think I'm in stage 4 which I never hit when I have my sleep studies. I think that would explain why I get the centrals at home but not on the studies. What is your pulse? As your can see I go into bradycar...

Forgot to add that the Sleep Study was on ASV also with no change and no centrals on both CPAP and ASV. The report reads no OSA with a AHI of .6 but since I was diagnosed in 09 with a AHI of 60. They felt it was best to kept me on CPAP.

Thanks Mark,

My BMI is 32.5.

Here is the flow enlarged


and here is a O2 with flow from 11 Jan

This happen about every other day and why I requested a new sleep study. I seen the sleep Doc last month and when the report showed no centrals she said see you in a year. This was at the VA. I do have appointments with both my VA and insurance PCP’s. I got my S9 from CPAP.com so I don't know if I s...

I’m at a lost. My pressure is set at 4.8 and I’m getting centrals over 60. If I try auto they go even higher. On my sleep studies I get no centrals. OA's are always under 5. I’m using an S9 Auto start. Could this be my machine? http://i1125.photobucket.com/albums/l592/JimDB/sleepy23Jan12.png http://...

I'm using a CMS-50D+. I'm using it in "live mode," i.e. put on pulseox, go to the SH oximetry screen, click on "start live." I get a valid display of data on the oximetry screen, then click the save icon. When I look at SPO2 on the daily screen, the scale is all screwed up like this: http://img808....

Well Mary spoke of three overnight oximtery collections that each returned no desaturatons. How does that reflect poorly on the doctor?

I believe you're posting in the wrong topic!

To M.D.Hosehead , I'm sorry, I'm the one that missed typed it reads .6 AHI. I need to look for my first study or request another copy. I just seen my pulmonologist, sleep specialist, last Wednesday but I don't think she read .6 AHI. If I have seen the report before hand I would have question the NO ...

Buspirone as a Potential Treatment for Recurrent Central Apnea http://clinicaltrials.gov/ct2/show/NCT00746954 The hypothesis is that buspirone is a safe, effective drug to reduce the occurrence of recurrent central apnea and irregular breathing found in the setting of heart failure. A secondary hyp...

Jim, something here isn't computing for me. On the diagnostic study your AHI was 0.6, yet they prescribed CPAP at 5 cm. Why? I was asking myself the same question, just because on a past study it was 60 AHI. At home your machine records AHI of 6 to 15 or 20, depending on pressure. Are these all cen...

I read that centrals can be caused by heart and brain problems like tumors of the brainstem and lesions in the clival region. so you should get some testing done also. I have a Cardiologist in Feb. and he is going to read the sleep study plus I'll have my report from the S9 and Oximeter. I need to ...

Have you looked at how long and how total the centrals are on a waveform display? I don't know just what to look for. I do have both Resscan 3.16 and Sleepyhead 0.8.8.4 pre bata If you don't have a blood O2 drop or an EEG arousal, many people will not call it an apnea at all, and it may not be harm...

I was using a pressure 0f 5.8 cm H2O and getting reading of 6-15 AHI
With the setting of 5 cm H20 I'm seeing 10-20 AHI
This is why I think it could be because I didn't hit REM in the Lab.

Thanks
Jim

Been on CPAP for a year and my Resmed S9 APAP has been showing centrals of well over 10. I showed my info to my doctor which did have a new sleep study done (Results posted below). I have been using the new pressure with no luck, still high centrals plus my total AHI has gone up. The lowest AHI has ...
