BiPAP Auto SV Advanced, Encore Pro 2, Card Reader

[uriahsky]

I have the Respironics BiPAP Auto SV Advanced along with the Encore Pro ver 2.2 but I only have Infineer DT3000 Serial Smart Card Reader, I don't have the USB version.

What I am finding out is that this won't work with the Encore Pro 2.0 software. Is that correct? Serial Card reader doesn't work with Encore 2.0?

Is there any work around? So that I can read the card? Any other software that will work or is there a inexpensive place to buy the USB Version?

Thank you,
Russ

Hi uriahsky,

I can't answer your technical questions, but our host, cpap.com, has the USB Encore Smart Card Reader for $79:

Do you have an SD card reader or computer that can read ordinary SD cards? If so, I would try copying the Infineer sleep-data files to an ordinary SD card. That might require first installing the generic Windows driver(s) for the Infineer reader---rather than installing proprietary Respironics drivers. THEN I would try to introduce that copied Respironics data to Encore using the SD card. I have no clue if that would work... but if I already had an SD card and reader, that's what I would try next.

I hope others here can offer better suggestions.

I did find a link to a DT3000 software driver but it didn't work out. I got an error about not being able to start the smart card services. I got this same error when I tried to install the Encore Viewer 2.0 software. It might have something to do with the fact that I don't have a serial port and I had to use a serial to USB converter to get the DT3000 to work with Encore 1.8. Is there a stand alone program that reads the data from the DT3000 serial port smart card reader? If there is then that is what would work. Then I could grab the data and put it on a SD card or get it to the Encore 2.2 software. But, I did find a USB DT3500 for 45.00 just now, so I ordered that. That should do the job. Thanks for the help.

The Auto SV seems to be doing the job. I haven't woken with a headache and I no longer feel the dull achy painful dense thick head thing that usually always occurs in the morning. I need to get back on a normal sleep schedule. Right now I don't fall asleep until late in the morning. 9:00AM yesterday. That was from months of waking with a headache and the only relief was more sleep.

But,

When I put the mask on it almost feels like I am not getting enough air into my lungs. Like I am not breathing deep enough. I am wondering if it is the machine not putting out enough air on the way in or stopping the flow too soon? Either that or I am just a little nervous about going to sleep, but is there a setting that might affect this?

Besides setting the max PS the main thing is to set the min and max EPAP between 4-15 to treat the OSA and leave the backup to auto for the CSA, Is that the main settings?

Then you tweak those things to cover the OSA and if the CSA is still happening then you dial in a rate in the non-auto mode for the backup?

At first, is that the main thing to setup? I also set the min and max PS, but I didn't see much more that is done when you first start using it.

I am still learning. I did find a short guide on setting it up with a patient. Is there a longer guide that talks about EPAP and IPAP and how you interpret and understand its affects.

Thank you,

I'll quote my other post in this thread, Uriahsky:

I would recommend getting an understanding doctor or RT in the loop for your self-titration on ASV. The Respironics Auto SV Advanced Legacy has the same settings and titration protocol as the current PR1 generation Auto SV Advanced model: http://www.healthcare.philips.com/asset ... otocol.pdf

Respironics would have you start out with these settings:
EPAP Min=4cm or patient comfort
EPAP Max=15cm
PS Min=0cm or patient comfort (0cm is auto-CPAP as your base modality; otherwise auto-BiPAP as base)
PS Max=20cm
Max Pressure=25cm
Rate=Auto
BiFlex=set to patient comfort

Depending how you subjectively respond, and nightly AHI data, adjust accordingly. It's not uncommon for patients to need a higher EPAP Min. Nor is it uncommon for PS Min to require change from 0cm (auto-CPAP base modality) to say 3cm or 4cm (now auto-BiPAP base modality). Servo ventilation will adaptively fluctuate IPAP on each breath, regardless of which base modality type is used (auto-CPAP or auto-BiPAP).

Please keep us in the loop and try to keep a doctor or RT in the loop. Good luck!

I placed Respironics' three "comfort" suggestions in red text above. If you feel you're not getting enough air, then the EPAP Min and/or PS Min are probably too low. Respironics would have the sleep tech and patient experimenting together with those three parameters---with the patient lying and rested as he evaluated the comfort of those three settings. The sensation of not getting enough air is a common comfort problem related to pressure that is too low. However that sensation is even more prevalent among CompSAS patients.

The entire EPAP range (EPAP Min ranging all the way up to EPAP Max) is for the purpose of automatically addressing your obstructive component. Just start EPAP Min high enough so that you don't feel uncomfortable. PS Min will be your "constant" IPAP boost during each breath. If you leave it at zero, then the three parameters I have highlighted in blue text cause your machine to behave like ordinary auto-adjusting CPAP-----that is until additional servo-ventilation IPAP increases kick in as-needed, per breath. If you set PS Min to say 3cm or 4cm, then those same three parameters I have highlighted in blue cause your machine to behave like an auto-adjusting BiPAP targeting obstruction-----that is until additional servo-ventilation IPAP increases kick in as-needed, per breath. Those servo-ventilation IPAP increases target the central component.

So in summary, those three blue-text parameters, together, can be used to address your obstructive component. But quick, per-breath servo-ventilation IPAP increases on top of all that will address the "undershoot" of a lacking central drive. PS Max and Max Pressure, together, will define how high those servo-ventilation IPAP pressure boosts can go. Those servo-ventilation IPAP boosts will adaptively go high, low, or somewhere in between---depending on how much or how little "undershoot" your central drive happens to present on any given breath. Additionally, the backup rate will detect occasional missing breaths, and commence the EPAP-to-IPAP transition as a startup nudge for central apneas.

Thank you very much for the info. That was very helpful. I experimented with those settings and I did find a much more comfortable setting. I can now make it about four hours without waking up. So I am on the right track. I am waiting for the smartcard reader so I can better understand the data.
Thanks again,
Russ
