RE: can someone read my oscar chart and tell me if it's good or bad?
yeah i hope to get at least Bipap soon. Last night i slept about 5 hours with the device (yay) but during REM sleep my central AHI went way up to 12 and then went down to 5, only for it to go back up to 12.
overall AHI was 6, of which 5.8 central.
when i look at my breathing patern i can clearly see that it is messed up, it's like my brain forgets that it needs to breathe out.
breathing in goes fine, but after that my brain gets confused lol
RE: can someone read my oscar chart and tell me if it's good or bad?
You are focusing on the right area. In REM sleep, things can go a bit wild with respiration increasing.
A further point on central events less than 10secs. I believe they can create "micro arousals" disturbing sleep, especially if in a repetitive cycle. It becomes a cumulative effect. Perhaps some people have a tolerence of these types micro events.
Most likely depending on each persons individual sensitivity.
Just a opinion, based on personal experience. It is worth what it is worth...
RE: can someone read my oscar chart and tell me if it's good or bad?
last night i slept about 8 hours with the device, and excluding the falling asleep part i did about... 7 hours with the device? this is a new record :-D
however the results don't make me happy and i don't know where to begin.
First of all: AHI of 8 for the entire night is ok, but where the heck did all those OSA events come from suddenly? i almost never had any of them since i used the device, not even after changing pressure. i don't recall eating something that could increase this, i also didnt have a stuffed nose and used the nasal strips as well.
Also, highest AHI was 20 but i can't tell if it's because of OSA or because of CSA.
If i did not have any OSA events then my CSA AHI would be around 3.5, so the OSA messed up my numbers big time :/
total OSA events: 29 events
total CSA events: 30 events
if i only had the 30 CSA events for a total of 7 hours sleep, won't these numbers be reasonably fine?

As previously discussed, we can't do much about central apneas, as most likely the job of some kind of bi-pap, which your doctor seems to acknowledge, but needs some 4 hour daily compliance history first, I suppose to be able to justify the higher cost machine.
Concerning the obstructives, normally these are dealt with by increasing the minimum pressure, and having a maximum pressure as a safety barrier to catch any other obstructive event.
I don't understand the statement "Also, highest AHI was 20". Your AHI for the night was just 8.2 ?
I find the big handicap in analysing your graphs is you being on a fixed pressure. Normally movements in pressure can tell us a lot. For example, in APAP mode, we would see the machine reacting to the occurance of hypopneas and obstructives. We could then titrate your machine so as to be able the control these.
You have only one fixed pressure, and it is most likely inadequate. But we are blind, we just don't know your actual pressure requirements. I think it would be also useful information for your doctor.
In this situation, we cannot give any explanation of the sudden variances in obstructives without this essential basic information. I think it would be useful information for your doctor.
I would like to revisited APAP, and set minimum pressure to 10, maximum to say 12, and let the machine do the work to see where it goes.
Of course hopefully you get a bi-pap to resolve everything.
As a note which I forgot to mention previously, sleep aids and pain killers can encourage the development of central apneas.

happy new year everyone! and thanks for all your help so far :-) this is the year i will have my sleep apnea under control and finally feel beter after dragging this along for about 8 years now
RE: can someone read my oscar chart and tell me if it's good or bad?
Happy new year to you.
I am sur 2015 will work out fine. I think you have all the compelling arguements now for your doctor to take notice. You have just to make sure you have the required compliance hours of at least 4 hours.
I think in most of France it is 4 hours also, but in my department 31, it is only 3 hours (for the social security to pay)! Why it is an exception, I have no idea, never found an explanation.
