So I should conclude that this type of phenomena is inconsequential to your health? Is the doctor right? Do you experience these end of night 'junk' centrals jack?


If I had a string of centrals shortly prior to waking up each morning, I'd be interested to know how much oxygen desaturation was occurring with them.

I'd love to see a closeup of one of those CA events. Just wondering if there's a chance they're actually obstructive and not clear airway events.

I think it is at least somewhat reassuring that there is no desat with those morning CAs.  Whether they are inconsequential to your health, I couldn't say.  What does your doc say about them?

The doc is concerned because I do have days when those O2 events ARE desats. She is opting to watch for another month to see if the therapy works to diminish either or both of the CA's and O2 events.

lets get your min pressure up to 7 or 8 and max to 15, to get rid of some obstructive stuff. There are desats at 2:30.

I think some more min pressure will help you more than the SWJ concern. Also for the rest of the night. Pressure induced CA normally settle within 12 weeks at the new pressure for most people and aren't associated with a large desat. It's just the body getting use to CPAP. I would sort out the obstuctive first, then see what's left.

From machine or charts for auto-cpap, set the min 1cm below median pressure, or 2cm below 90/95%. max at 20cm for now. Forum will help you fine tune settings

ajack, I don't have much obstructive!!..the night I posted is only 2 OA and 2 Hyp all night. But I do take your point. I think I will up my base pressure a bit. BTW, over the first month of therapy, the CA's were 68% of all events...thats pretty high.

I have in the last 10 days, cut the total number of events in half, but most are still CA. I do think the therapy is having an effect.

You are ticking along nicely, I doubt you will need to move from cpap.
the median pressure was 7
your 95% was 9.84 and max pressure was 10, the same as your machine setting.
There wasn't much of a change in AHI from your other chart, but the median and 95% pressures seen constricted now.

The reason I would increase the min pressure 7, to be abound the median. Or 8, to be closer to 95% if it is accurate, was because this would help the OA, H and flow limits. It shouldn't affect CA and it may help fix some desats.

Pressure induced centrals is fairly common and settle down for most people within 12 weeks.
The lifting the max to 15 isn't needed as much, it was to get machine max setting out of the way. To see whether the 9.84 is an accurate 95% number, given the max on the machine is 10. The machine may be getting too choked down. This may increase your centrals a bit while you are testing, but it will give you an accurate 95% pressure, that you can work with. You may even want to move to a fixed pressure, a bit more that the 95% works better for some people..

Have been sick with flu , nausea + cpap does'nt work Too-funny .

Anyway , My GP is sending me for a new polysomnogram to check where things stand. Could only get an appointment for the 30th of Jan.

In the meanwhile I will be getting a new oximeter to see what happens during the night with cpap.
Off topic , does anyone know if the PM60A pulse oximeter is compatible with sleepyhead?

Glamdrhel, The PM60A, although made by Contec, is not directly compatible with SleepyHead. It is possible that the SpO2 Assistant software may create a file that can be read into SleepyHead, but nobody has tried.
Most of us use the Contec CMS50 D+, or E, or F versions which, as I recall, are less expensive.

Glamdrhel,
In addition to the Contec models that pholynyk mentioned, you can also use the "I" model.   It is like the "F" model but allows for multiple recording sessions as opposed to only one.  The 50I also reports a Perfusion Index parameter.  (Note:  I have yet to figure how to do anything useful with this data though.)  Also, you don't need to spend extra for the bluetooth option.  Sleepyhead doesn't use this feature.
