Enhanced Vpap Adapt SV

DrowzyDave · Post by **DrowzyDave** » Sun Jul 06, 2008 10:01 pm

Hi all,

I have been away from the forum for awhile. I saw on Resmed's website that they have an "enhanced" Adapt SV. I have had my Adapt since August of '07 and love it.

I have tried to search fhe forum for this info but am not having much luck. Does anyone know is the "enhanced" Adapt a new machine or merely a firmware upgrade? I am particularly interested in the "enhanced" version's ability to track AHI. I always thought it was a little odd that a "hot rod" machine like the Adapt did not track AHI.

Any suggestions on how I would go about getting mine upgraded? If it was firmware, I could do it myself -- if I could get the file and instructions. I am pretty sure my RT would not have the slightest idea how to do this. Or would I be better off getting my doc involved and possibly working it into a prescription. My doc (GP) has been very supportive and is really more help than the sleep doc has been.

Thanks for your help.

Dave

The 'enhanced' Adapt SV is not a firmware upgrade. It is a totally new machine. I'm using one. Your Adapt SV cannot be upgraded, however, it can be replaced with an 'enhanced' model. I will know shortly what parameters can be tracked on the 'enhanced' Adapt SV.

It is possible that the upgrade was software but as banned has said, Resmed are saying that there is no offer of an upgrade from the older model.

The older Vpap Adapt SV does actually provide a lot of detailed data but the one bit of data you could not get was AI & HI scores. In the clinical sense, the data that the machine does provide is very adequate for what the machine is designed to address (centrals and irregular breathing (i.e. CSR (CheynesStokesResp) & Complex Apnea).

The Reslink module allows for flattening data and SpO2 data to be added to the existing data the machine records and can be downloaded (breathing rate, minute ventilation, tidal volume, pressure, leak).

See example Vpap Adapt SV output here
http://www.internetage.com/cpapdata/dsm-vpap-adaptsv/

AI & HI scores are very low level and somewhat subjective in regard to the effectiveness of an SV machine but I believe the enhanced model does offer that info. The main differences between the new & the old are (1) the increased EEP setting (Epap equivalent) which has been raised above the prior max of 10 CMs. And (2), the machine's maximum pressure was raised from a ceiling of 20 CMs to a ceiling of 25 CMs (EEP + MinPS + MaxPS => will not exceed 25 CMs)

I think, based on feedback from banned, that they may have reduced the incredible response speed of the machine to the smallest of breathing changes.

My own experience of the Vpap Adapt SV when compared to the Bipap Auto SV is that the Vpap SV 'spins on a dime' by this I mean that if I as little as yawned (thus changing my breathing pattern) the machine instantly applied PS to bring me back into line. It is a somewhat 'in your face' sense of control & it would seem perfect for anyone with disordered breathing who needs that disorder tightly controlled.

If I could add one more setting to the Vpap Adapt SV it would be a to control the speed of response with settings - say 1 to 5 - that adjust the level of response to changes in breathing that the machine monitors. IMHO that would broaden the scope of who might be able to use the machine.

I will probably switch back to my own Vpap Adapt SV tonight for 2-3 nights - I recently found that by adjusting my GERD medication, I have been able to greatly reduce nasal congestion & stabilize my nightly sleeping such that I think, the Vpap Adapt SV will feel a lot more comfortable than it has previously. I say this in the full knowledge that the Vpap Adapt SV was not designed for people such as myself who don't have obvious centrals nor serious irregular breathing.

Thanks for the info.

DSM, based on what you have said I may be happier with my old Adapt than a new one. I like the fact that it is so responsive and find it quite confortable -- although occasionally its rapid response has awoke me as I was just drifting off to sleep. Usually when my mask starts to leak is the only time this happens and is probably a good thing since I can adjust my mask for a better fit for the night.

Thanks again for the info. -- I knew this was the place to go -- not the DME and it sounds like I should leave well enough alone at this point.

I'm sure banned will give his perspective as someone who has used both the old and new Vpap Adapt SV.

Good luck

DSM

PS mask leaks are certainly an issue with it. Leaks skew its performance.

I have posted this in the BipapSV vs AdaptSV thread as well. What it shows is the data I get from the machine via either a serial null modem cable or from the SM datacard in a Reslink attached to the machine. I had thought the Reslink would include flattening data but apparently it doesn't. Reason I thought this is that is what I get extra from a Reslink attached to an S8 Vantage over the standard data.

Here is an extract from the Adapt SV that covers last night and compares with 4 prior nights. As mentioned - last night was fine & the machine was very nice to use.

http://www.internetage.com/cpapdata/dsm ... -jul08.pdf

The data shows one interesting aspect worth understanding & that is that the leaks shown were clearly adequately compensated when you look at the matching periods for pressure minute-ventilation & tidal-volume. That says to me that the machine handles leaks better than I had previously thought it did.

Does anyone know if the F&P 432 will pass the Learn Circuit on the Enhanced Adapt ASV? I LOVE that mask and miss using it. The Quattro is pretty comfortable but I like the under chin design of the 432.

The F&P 432 will pass LC just fine. In fact, any mask will pass LC. The problem is you will be listening to alarms all night.

DrowzyDave I have the F&P 431 mask and it will not pass the circuit test on my Enhanced Adapt SV. I went from CPAP to BiPAP (Respironics BiPAP Auto M with Bi-Flex) which I was on for a over a year, now I have this ResMed VPAP which I started on in May. I think it is great! I am not an old timer as far as this Sleep Apnea thing goes I was first diagnosed in Jan of 07, I have had six sleep studies done since then, I have Complex SA, Anyway this VPAP has been a real Godsend for me, I am finally getting some sleep!

I have the ResLink and Pulse OX and Cardreader and all the rest. I have found there are some kinks in the software ResScan 3.5, If I have two separate sessions, (normal sleep at night and then a nap later in the day) I cant get it to down load the the detailed data, it just hangs up, but it only does that with two destinct sessions.??? It might be because of Vista also, but 3.5 is suppose to be for Vista. There are a couple other small quirks in the way it displays the Oxtimtry data, hopefully they will get that resolved, in an update.

I am very interested in your 3 lpm O2.

That seems a high dose ? -- am guessing you have some lung disorder ?.

Are you willing to share (even privately) your reslink data when you are on 3 lpm O2 - I would very much appreciate looking thru it.

I have 3 years of my own data from various machines & am happy to make that available.

Cheers

DSM You know back in Mar of 07 I was complaining to my SA doc he's a neurologist that my CPAP wasn't working, he had me take home a over night pulse Ox, about 2 weeks later my DME called and said the doc had ordered an Oxygen Concentrator and wanted me on 2 Lpm of O2 with my CPAP, I never did find out what the overnight Pulse Ox was. But I know during my initial sleep study I went down to 70% and the doc said I had severe O2 desaturation. Anyway I have been on O2 every since, and I when I had my 6th sleep study this past May for VPAP titration, I had a new SA doctor he's a Pulmonary doc and is board certified in Sleep Apnea, anyway my VPAP titration study was done with out O2, and afterward the Doctor said he wanted me on VPAP and he wanted the O2 increased to 3Lpm. I don't have any lung problems that I know of. Anyway I don't mind sending you a couple of my Rescan data reports, This VPAP has been really great! most of the time my AHI is below 5, and AI 0.0. and my o2 sats mostly have been above 90 and 95% I must admit I am sleeping but I do still wake up and I do still have some problems with being tired and fatigued. I will do a PM.

Umm, not according to the machine. My 431 and 432 both failed. (I really wouldn't use the 431 anyway.)

Wouldn't the alarms indicate that something was not working properly? Unless something has drastically changed, all of the information I have read is that a mask that will not pass LC unmodified should not be used.

that does't seem to make sense. If it passes the test, then why would the alarms be going off? Anyhow, they did not pass the test so it's academic.

When the other fellow said the sensitivity of the enhanced machine was "reduced" I think what he mean to say was that it was "increased." It was very confusing the way he wrote it. I think what he was trying to say was that it will deal with "events" that are very tiny, ie reduced.

I made the statement based on a experiment with a Mirage Micro nasal mask. I set the VPAP SV mask setting to 'Ultra'. It passed LC, but alarmed constantly. I should not have generalized. You are correct. Use only ResMed VPAP Adapt SV approved masks.

It did pass the test on a few non-resmed masks, but several others failed the test. The machine is so sensitive that apparently even changing the cushion on a mask requires a re-test. I put a new cushion on my reside Activa mask, which prev had passed the test, so I did not retest it. For the next two nights I slept very badly, was wondering what was going on. I noticed too that if I took the mask off the auto-stop feature no longer worked. Bien étrange! Then it came to me, re-do the test circuit. Did that, and everything was back to normal, started sleeping ok again, and the auto stop worked as before. This is the only machine that has ever worked for me, and this since my first machine in 1986. Never really slept good until I got this machine, it is from heaven.
