AHI is getting worse. Having more centrals

RE: AHI is getting worse. Having more centrals
Looks like REM sleep aggravated apnea. I have it too.
That is why it is important to look at more than the AHI - to figure out when it happens and determine a why.

RE: AHI is getting worse. Having more centrals
Since turning my EPR off and setting my min pressure to 7.4 my AHI has been 5.8, 1.5, 3.39, 11.78, 5.85 and 16.72.

RE: AHI is getting worse. Having more centrals
First, most of your night remains pretty clear, but these periods of post sleep onset periodic breathing and apnea are really concerning. If you are under a doctor's care, you should request a consult. This kind of pattern can be related to medications or heart conditions; are you aware of any of these factors playing a role? This could also be a complex or central apnea problem that is not going to respond to CPAP. I know of no strategy to break a sustained pattern of central apnea using CPAP.

Since this pattern is continuing, and has a defined pattern following sleep onset, I have to say I'm out of my league to make constructive suggestions with your current equipment and what little we know of your diagnosis. If you can shed any light on this with results from your sleep study, or existing health conditions then perhaps we can help on the forum, otherwise I think you will be best served by bringing this to the attention of your physician(s) for evaluation and diagnosis. A predominately central apnea and periodic breathing pattern like this would be better treated by adaptive servoventilator (ASV), rather than CPAP, and you will need your doctor's assistance to move in that directions.

RE: AHI is getting worse. Having more centrals
I have had stress tests, ekg's, chest x-ray's, seen a cardiologist, etc. The Dr. says I just have A typical chest pain, my heart is fine and I've never had a heart attack. I do have high blood pressure, non alcoholic liver disease and a domed right diaphragm. Hydrochlorothiazide is the only thing I'm taking for med's. I was supposed to go in today for my 30 day follow up with my sleep doctor. But they cancelled due to a medical emergency and now my next appointment isn't for another month. If I had complex or a central apnea problem would it happen every night. The sleep study showed mostly hypopnea's, some obstructive and a few central apnea's. My blood oxygen went down to 86%. Here are some other night I have had.

One other though that worked for another member. Clusters of apnea can be caused by obstruction created when you tuck your chin towards your chest. This member used a buckwheat husk pillow, but any option, including soft cervical collar, neck roll or whatever works to eliminate this possibility may resolve the clusters. http://www.apneaboard.com/forums/Thread-...ata?page=3

Not necessarily. Apnea events vary from night to night, so inconsistency between nights may happen.

RE: AHI is getting worse. Having more centrals
Last night was much better. Why am I having such a drastic swing? Does anyone know what the response setting on the autoset 10 does? It has a standard and soft setting. Does it control how fast the pressure ramps up after an event?

RE: AHI is getting worse. Having more centrals
SLEEPRIDER, would bringing the max pressure setting down from 20cm to around the 10 / 12 cm mark be better for the algarithum to work more efficiently? Just thinking that he's hovering in the 10's for 95% and may help with the ca's, or does the breathing pattern dictate the type of ca's occuring?. Just trying to learn.

He doesn't seem to exceed 12, so reducing it to that doesn't seem likely to affect anything adversely. 

And if I recall correctly, setting the maximum too high might encourage the CAs (?)
