My initial nights with ResMed S9 VPAP Adapt 36037

My new S9 VPAP Adapt (36037) is super fantastic! I've now used it for 4 nights with AHI's of 0.72, 0.31, 0.29 and 0.12. Last night (the 0.12) I was foiled from a perfect 0.0 by a hypopnea as I was waking up. I'm sure it's only a matter of time before 0 is achieved. But, the most important thing is - I feel GREAT upon waking in the morning! This is the first time I have felt fully rested.

I started CPAP'ing last December and have progressed from an S9 Autoset to an S9 VPAP Auto to a BiPAP AutoSV Advanced (950P) and finally to the VPAP Adapt. There'll be no more auditioning of machines as this one is a keeper for me. I am adapting to it quite nicely. It is also very comfortable for me, in spite of the higher pressures used at times. For the first time since I've started CPAP'ing I don't approach bedtime with apprehension. I'm now looking forward to going to bed, if you can believe it! I wish everyone could afford to have one of these machines.

For those interested, here are a couple of screenshots showing the label and firmware used in this machine.

great to hear. what was the primary reason you went from APAP to VPAP machine. preponderance of centrals? how did that decision get made, sleep doctor, you and the DME? what were the elements of the APAP only therapy which were not solving your AHI problem?

I notice that you have a different software version SX474-1300 than my 36037 which is SX474-1102. I wonder what changes have been made to the newer version? They are great to sleep with and I'd hate to go back to regular Bi Pap after using the ASV.

My sleep doctor has been with me all along the way. We did not have enough justification for him to write a prescription for the ASV machine, even though he agreed that I would benefit from one. I had several issues. At the start, the initial machine triggered asthma attacks that I never experienced prior to CPAPing. I wound up in the emergency clinic twice before concluding it was the CPAP machine that was the trigger. My numbers were relatively good, most times under AHI 5, but I had many arousals and felt tired in the morning. The second issue was centrals. I always had them but not enough to average over 5/hour. Some nights were much higher than 5 and sometimes in clusters, but usually spaced out over the night. But, not enough to justify him prescribing an ASV. The S9 VPAP Auto worked good in S mode (spontaneous), but I wasn't able to get the right settings to control the centrals to my satisfaction. So, I have done it on my own but with my sleep doctor's knowledge and agreement. He wrote prescriptions for the S9 Autoset and the S9 VPAP Auto. I bought the others.

Incidentally, I am using my new VPAP Adapt on its default settings.

I have to agree that they are wonderful machines. I wish my budget would allow me to keep a spare for when something happens to this one. I guess that is when I will force it into my budget. I hope to never go back, like yourself I could not medically justify having insurance pay for it.

It didn't take long to get my first ZERO apnea night! I also recorded my oximetry data for the night and they were great as well.

Congratulations on the big smiley face. I am currently using the slightly older Adapt model 36007 and I have had more than a few of those myself. Kinda nice to see.

Comment,

That Asthma attack got me interested so I Googled: "Asthma triggered by CPAP" and got this:

Answer:

Good question and the short answer is no. In fact, treatment of sleep apnea with CPAP has been cited as a factor that may make asthma better. I consider asthma and allergies to be the same disease. What is occurring in the nose is also happening at some level in the lungs throughout your life. It just may not cause clinical symptoms. But, invariably, at some point in their lives, patients with environmental allergies may develop prolonged coughing after colds or frank asthma. The good news is that respiratory symptoms wax and wane throughout your life and are very likely to become less troublesome at some point down the road.


p.s. I was interested in this subject matter b/c my nephew who suffered from Asthma ( but did not want to quit smoking), suddenly died from an Asthma attack at age of 20. It happened 15 years ago.

Well....there are many asthma triggers. Pressure changes are known asthma triggers. Try googling "asthma and flying" and see what you get. I don't want to argue this point as it varies by individual.

Hi Folks,

I'm a Newbie here on this website, but certainly not new to CPAP (note my signature block below). However, last night was my first time ever using VPAP (ResMed S9) and I was so delighted with the results that I felt I had to post them here.

A couple of months ago I was diagnosed with AF (Atrial Fibrillation), in addition to my other known heart conditions, and I was finding that my ResMed S8 CPAP machine just wasn't "cutting it", so I went to see my Sleep Doctor. He trialled me on the ResMed S9 CPAP and the ResMed AirFit F10 mask (which leaked like a sieve, with the max. pressure of 16!!!). Over 11 nights, my AHI readings were all over the place, from 4.8 to 33.0, and he diagnosed me with Cheyne-Stokes Respiration and Central Sleep Apnea (CSA). I was wasting my time with the S9 CPAP and now needed VPAP.

So last night, I set up the new S9 VPAP Adapt (which looks exactly the same as the S9 CPAP), humidifier, and new ResMed SoftGel mask. Here's my VPAP diary entry from last night:

(Tue, 8Jul14): went to bed early (as I haven't had a decent sleep for ages) at 7:50pm, wearing the new (Mirage SoftGel) mask (nose only) and two, blue (SleepTight) chinstraps. Mask fit, on sleeping & waking, was good . The mask itself was very comfortable, and as far as I know, did not leak at all overnight. I had an excellent, sound sleep for 11 hours, waking at 06:50, with an amazingly minimal AHI of 0.4!!! This is a vast improvement for me (last night on CPAP, AHI was 17.2). My mouth wasn't dry (Humidity=4.5; Tube=27), although my lower teeth and lower, front gums were sore. I bound my mouth closed very tightly with the 2 chinstraps, and my wife commented that she heard my teeth 'chattering' (?or something?) overnight. I was aware - at one point only - of some air escaping from the corner of my mouth. I need to experiment more with the tightness of the chinstraps, but otherwise I'm very happy with this result on my first night of the VPAP trial.

I hope this result continues, or even improves, as time goes on.

they're actually identical physically, the only difference is the software that runs on 'em

DecentSleep1, bravo on your success! Those S9 VPAP Adapt are sure the way to go with CSR. But in your registration it says: S9 VPAP™ Auto BiLevel Machine. The word "Adapt" is missing.

Well, it is not listed as such.

Hi Guys & thanks,

Correction: The VPAP S9 (on its own) is actually slightly lighter (at 830grams/1lb 13oz) than the CPAP S9 (835grams/1lb 13.5oz). However the point I was trying to make, is that when you include the power pack (at 730grams/1lb 9oz), it is heavier (and bulkier) than my older ResMed S8 CPAP machine (weighing 1450grams/3lb 3oz).


I'm a bit disappointed that the S9 together with its power pack is actually heavier than the S8 with power cord. Not a big deal at home, but I do travel a lot and every gram (or ounce) makes a difference, especially in carry-on bags on aircraft. However, a very much lower AHI (and hence better sleep) will make it worth it, I'm sure.

I suspected as much, as the VPAP S9 (on its own) is slightly heavier than the CPAP S9.
is REF: 36377 however. It is a rental machine (used for trials) & not for sale, so perhaps that's the reason (unless it's a later version).

36377 S9 VPAP Adapt - Asia Pacific

the vpap adapt isn't listed on the equipment pull downs for various reasons of incompleteness... just leave the machine blank and put S9 vpap adapt in the 'additional comments' section.

unless there's some difference in the asiapacific version, I'd be very surprised if there was a weight difference.

I've taken apart an elite, and a vpap adapt, and there is no difference internally.

I think that the following Resmed's patent describes the operation of the present S9 VPAP Adapt. Except there are no separate mask pressure leads going from the mask to the machine in present machines. So this patent might relate to a more advanced embodiment for future machines.

After you download it by the link then click the Download PDF to see it clearer.

IMO, it's unbelievably advance.

Possible present S9 embodiment. It shows no mask pressure sensor leads going to the machine.
The mask has vents directly from it. The pressure at the mask is calculated by the pressure at the flow generator exit less
the pressure drop along the air hose :
