And here is last nights with a incomplete O2 and pulse as I thought I was going to stay up and then went back to bed for a little more..

I cannot make out what is different between the two nights..

I can't see anything significant in your charts either. Your AHI is low & your SPO2 traces appears acceptable, so I still lean towards UARS.
Have a look at this video. There is also a link to it here on this forum somewhere. It explained a lot of things to me. Made me understand why I feel so washed out and incapable.

Doing a little research and found this: in a report on upper airway restriction syndrome

"Positional therapy Obstructive sleep apnea is typically worse when sleeping in the supine position compared to the lateral or prone (stomach) positions. Sleeping on the side and avoiding sleeping on your back is recommended in patients with mild obstructive breathing in sleep who are not using nasal CPAP. If you are on CPAP, you may sleep in any body position you desire since the CPAP will protect you when on your back."

NOT True with my case my machine may save my life but if I get on my back I get HIGH AHIs...

Now if only we knew what we need to fight it...

I have noted my system going for high mask pressures...could that be the right idea...?


There is a new type of machine something about maintain full air supply or something...it seemed the next step above Philips Respironics BiPAP AutoSV 960 but I can not find anything on it.

Where does this bloke come from? He is stating the obvious, & he's incorrect. - we can do that!
Your are right. It is not a good idea to sleep in any position other than on your side. In my case, I sleep only on my side, but the UARS problem still remains. In nearly 15 years of xPAP therapy, I am no further ahead, but at least the medical profession is beginning to recognise UARS as a true diagnosis. If your airway restricts, your machine will respond by raising the pressure until the event is relieved. Mask leaks will rise concurrently, your SPO2 will drop and your pulse rate increase.
Its not what happens that is of concern. It's how you feel next day. THAT is the telling effect of SDB, & don't we know it? How to fight it? I don't honestly know, but there has to be specialists out there who have researched the problem & their determinations we hope, will render us an effective treatment. For the time being keep up your xPAP therapy & continue to monitor every night both SH & SPO2. Soon patterns will appear pointing you (& your doc) towards a solution. You could try the "Snoreblock" device I mentioned in a previous post. $16 is not a big expense in the overall scheme of things. It could easily work for you.

Thanks, I have no doc as he was a quack....

Still looking for that brand new kind of CPAP machine.

No Doctor eh? I understand that. I haven't had a regular sleep doctor since diagnosed. I am reluctant to call a doc a quack, but some come close. I think sometimes they forget who is their patient & what the patient is trying to achieve. However, that said, in AU to get the assistance we SDB sufferers need we have to go along with them and hand in hand as it were, attempt to find a solution. We must remember they have years of training & experience. If a doc is of no help - change docs. Your primary care physician is the key. He/she can be a great help in your quest for successful treatment by referring you to one & then another until you succeed. You currently have a sophisticated ASV machine. A machine that's difficult sometimes to come to grips with. Perhaps that's an overkill & could be causing your frequent arousals. Good luck -

As I cannot post links to [DME Supplier forum URL reference removed] here is interest post on these new machines:

Thanks, jnk. I see from that comparison chart that Resmed now offers an S9 VPAP COPD model:
http://www.resmed.com/us/products/vpap_ ... nc=dealers

That S9 VPAP COPD is probably less expensive than the more versatile S9 VPAP ST-A w/iVAPS machine. Apparently what differentiates the S9 VPAP COPD model from the ordinary S9 VPAP-S is that the settings are all defaulted to COPD-typical values, to be used as INITIAL settings that require follow-up customization (IPAP, EPAP, TiMax, TiMin, Rise Time, Trigger Sensitivity, Cycle Sensitivity, PS). That's also what happens with settings when the S9 VPAP ST-A w/iVAPS is placed in COPD treatment mode: COPD-typical settings are defaulted as a starting point requiring patient-specific customization. Those COPD-typical settings encourage CO2 depletion in COPD patients. Additionally the higher PS value will mechanically offload more COPD-related work of breathing (WOB) than a lower PS setting would.

The possible show-stopper for you, Slinky, is that the S9 VPAP COPD model has no backup rate. And if you and your doctor are going to endeavor adding more oxygen, then it might be a good idea to use a machine with a backup rate to compensate for the iatrogenic respiratory-drive response we discussed a few posts up. The volume assurance of iVAPS or AVAPS (but not offered on the VPAP COPD model) probably isn't a bad idea either. Slinky, I'd also suggest asking the doctor if it's a good idea to gradually edge up from 2L O2, allowing plenty of time for your respiratory drive to adapt to each smaller increment of supplemental O2. As COPD patients perfuse less O2 and retain more CO2 over time, their respiratory drives essentially re-adapt to those gradually changing chemoreceptor inputs (O2 and CO2). That gradual re-adaptation sometimes makes hypercapnic COPD patients more prone to an acutely reduced respiratory drive in response to supplemental O2.

Thanks I appreciate the availability of Sleepyhead, but I have some anomalies with the printed Daily Report on:

SleepyHead v0.9.8-1 Testing Open GL with Mac OS X Yosemite v 10.10

1. On the Leak Rate graph, there are 2 plot lines, identical in shape, but displaced vertically by about 34 units. I presume the upper graph is the correct one. Comment?

2. I would appreciate it if the labels to the left of these graphs had the (physical) units of the values of the plotted lines specified, perhaps as a second vertical line of text on each graph; and also in table colums.

3. On the By Pressure graph (I only have one constant pressure - 5 cm H2O) there are some numbers, so what are they? eg Total, Peak, or Average numbers? Something Else? Also over-layed on this table are some graphs: a grey triangle with apex at 4.5, Blue, Brown, Yellow, Brown and Red triangles with different Apexes, but all peaking at 5.5. All triangles have a base 2 units long.

4. To interpret these data, I would like a guide indicating levels on the graphs that should be of concern, to the extent this is possible; or perhaps if no interpretations are to be provided on this site, available references which do explain the significance of the values of the values of these parameters.
