Pugsy,
THANK YOU, THANK YOU. I followed your directions, and the detailed graphs appeared. I have printed the manual & now I will have to study it. This forum is fantastic! I really appreciate all the advice & help. Question: Which of the graphs should I first study?

Not even DreamDiver himself who has either CompSAS (called also CPAP-emergent Central Sleep Apnea), or CSAS. So MAXDRI is still left unanswered.

Well, someone with an S9 VPAP Adapt, put it on, try and fake a few centrals, and publish the results.

To fake a central, you have to stop breathing, but not close off your airway. It's a little difficult to do, but I've done it on my S9 and PRS1 Autos.

If you get centrals recorded, it would show the machine records them. Unfortunately, if you don't get any centrals, it wouldn't prove it never records centrals, just that you couldn't fool it.

Thank you Pugsy, with your directions, I was able to downlaod detailed graphs.
Henry Jr. said "The ResMed rep said when S9VPAP Adapt is operating in ASV mode, it will never identify a CA because the ASV algorithm should always adjust/increase pressure to prevent a Clear Airway even from ever happening.." Maybe that is why, when I findally was able to download the detailed graphs, the area for CA was empty?

Nathe who has compSAS provided these graphs by S9 VPAP Adapt and ResScan:




Notice the poor control of leaks that Nathe had, most likely b/c of the Aloha Nasal Pillow CPAP Mask.



Notice: no CAs are shown.

That is my understanding also. Centrals aren't flagged at all.
There was a discussion a while back about this little bit of detail when one of the forum members was asking the same thing and in his case his doctor specifically wanted centrals to be flagged and after verifying with ResMed that centrals weren't flagged then they switched RX over to the Respironics ASV machine which does flag centrals.

Hmm just checked my ASV; never have seen a central. Somebody want to try and hold their breath?

Someone send me a free machine and I'll try it.

Sorry for tuning in late - note the date on that graph of mine you posted - it was in January, which was the first month I was on therapy. I was not using the Aloha then. In fact I don't believe the Aloha was even released for sale back then. I was using a Swift FX.

Also, I have much better control over my leak rate now and it is usually below the red line. I bought the Aloha when it came out and I am still using an Aloha, and like it a lot.

As for the issue about my model of machine not distinguishing between centrals and obstructives in ResScan reports, I believe this was studied at length, at my inquiry, by another more technically-trained member, whose name I don't immediately recall. He did a great job with the data I sent him at his request, and figured it all out. His avatar used to look like a squirrel although maybe he has changed it since.

I think if you search under "algorithm" + "central" + "ResMed" you will quickly find his research, conclusions and explanation.

I like my machine. I think it has done a great job for me. But I have never used the ASV Phillips makes/sells so I cannot compare the two.

Hi Nate, it's nice to see you again.

A question, you mentioned that you have ComplexSAS but I don't remember if you have it as a result of having emergent central apneas after usage of a CPAP?
My other question is if you have selected the Aloha pillows over the ResMed Swift™ FX CPAP Nasal Pillows, for any reason?

My diagnosis was as follows:

1) Central Sleep Apnea complicating CPAP treatment of Obstructive Sleep Apnea (Central Sleep Apnea Due to Medical Condition, Not Cheyne Stokes (327.27))
2) Obstructive Sleep Apnea (327.23) (AHI=29.0 events/hour)
3) Periodic Limb Movement Disorder (327.51) (PLM Index=15.9 events/hour)
4) Physiological Hypersomnia (327.10) — ESS=16/24)
5. Nocturnal Premature Ventricular Contractions (427.69)
6. Nocturnal Premature Atrial Contractions (427.61)

Comments: …The degree of sleep fragmentation and disruption of sleep architecture places the patient at risk for cognitive impairments and metabolic sequelae including hypertension, cardiovascular disease, diabetes, and the metabolic syndrome.

After reading it and describing to my doctor how absolutely miserable I was during and after the constant pressure of the CPAP sleep test, I was able to persuade my doctor to skip the 6 week CPAP home trial and give me a third sleep study whose results qualified me for going directly to the ASV made by ResMed as described above and below.

As for the Aloha, if you will type NateS and Aloha into our search box, you will find detailed descriptions I posted regarding my experiences with the Aloha and why I think it is superior to the Swift FX, one advantage out of many being the articulating angle by which the pillows can approach and enter the nostrils. Also many useful posts written by other Aloha users.

Regards, Nate

PS - In addition, the cheek straps or "hockey sticks" on the Aloha are rigid in the vertical plane, which tends to support the placement of the nasal pillows directly below one's nostrils, in most cases preventing the pillows from slipping down away from the bottom of the nose, which was a constant problem for me with the Swift FX.

Reply,

Thanks Nate. I am going to try the Swift FX for 30 days. IMO, the most important issue is the double silicone flaps on the pillows, that Resmed offers in the Swift FX. All the rest, be it the wire clip per Papit or fixing the headgear, is marginal. I assume that you are wearing the chinstrap with it. BTW, I have yet to see a decent leak graph from you and Papit while on those nasal pillows.

Comment,

What stands out from your diagnosis is that you have CSAS related to CHF.

Thanks to all of you.
I have determined that I am using the correct version of ResScan for my ResMed S9 VPAP Adapt.
I am also able to download all the detailed reports.
I haven't done that for several days - due to urgent events in my life.
However, in the daily report from my machine, it states that my leaks are in the 15-25 range. YEA!
It also says No AHI and NO AI.
Does that mean my treatment is working? And preventing the AHI and AI from happening?
I guess I can answer my own question by downloading the detailed data. If the detailed data confirms that I have No AHI or AI, then this ASV machine is amazing.

Yup. And yes, it is amazing.
