DeVilbiss Intellipap questions

[Massey]

Okay, I just got my new a IntelliPAP AutoAdjust Travel CPAP Machine and tried it out last night. My old machine was a Goodnight 420E with pressure setting set to low 4.0cmH2O mid 7.0cmH2O high 10.0cmH2O. When I used the Goodnight, it would hover around 7 pretty much all the time. The Intellipap doesn't seem to have a median pressure setting, and seems to hover at the low end, 4.0 until I fall asleep. It's noticably harder to fall asleep, and less comfortable at the lower level (perhaps because I'm used to 7 now?).

With the new machine I now have access to the data, and here's what it's telling me:

Time: 3.2 Hours
Mask Leak Time: 0 % of total
AHI: 8.1 Per Hour
EPI: 18.8 Per Hour
AI: 0 Per Hour
Average Pressure: 6.4 cmH2O
HI: 8.1 Per Hour Average
Leak: 28.1 L/min
NRI: 0.3 Per Hour
Avg. Est. Tidal Vol.: 596.9 mL
Snores: 0 Events Avg.
Breath Rate: 17 bpm
Max Pressure: 8.8 cmH2O

My concern is the 8.1 AHI reading. I understand from reading other posts here that < 5 is recommended. Also, while I have been able to sleep through the night consistently with the old machine, I woke up twice with this new one (you can see the short reading time above).

Do I need to change the pressure minimum on the Intellipap to 7 to make it more similar to the behavior of the Goodnight?

There is a delay setting that may not be set to zero -- it defaults to a longish time delay. I set the delay to zero when I set up my machine, and am not sure if the delay is actually a ramp or if it is a delay before the ramp starts.

Yes, I would definitely bump up the minimum pressure to 6, 6.5 or 7.

In APAP mode, the delay is the period of time during which the machine will collect efficacy statistics but not make pressure changes. It should be set to the average time it takes you to fall asleep. I left mine at the factory default value to 20 minutes.

Not to highjack this thread, but I have a different Intellipap question.

The booklet that comes with the Smart Module says:

Only use SD cards provided by your healthcare provider. Other cards may be incompatible or not function properly.

Hmm...in one sense, this kills an advantage that I thought this system had (being non-proprietary). In another sense, I thought that SD cards were akin to a floppy disk and can't imagine why one would work and not another. Formatting? Again, I'd guess that somewhere between software and module, formatting would be covered.

Anyway, I've only had the machine for a couple of hours, and I'll probably never need more than the single SD card provided, but I'd still just like to know.

Why can't any SD card be used?

I don't know if the SD "HD" cards can be used, but I have used a standard 4GB SD card formated as FAT16.

I looked up the number on the SD card shipped with my Smartlink kit, and discovered that it was an ordinary Samsung 1G SD card.

My guess, buoyed by bonjour's success, is that any SD card 4GB or less should work. (Cards over 4GB use the SD-HC spec, which probably won't work)

Thanks a lot, y'all!

OK, next question.

On another thread, I read that there isn't an oximeter available yet for the port in the SmartLink module.

Does anyone have any info on when it will be available? Price range? Any thoughts on the value/challenges of incorporating an oximeter into one's data collection?

It sounds like a good idea to me, but I really don't know too much.

According to the info on Cpap.Com, a Nonin pulse oximeter will work. I looked at the user manual for the Intellipap auto, and I saw no mention of using a pulse oximeter. Sometime down the road I plan to get an auto, and I was thinking either the Intellipap or the ResMed Autoset II. If there's no oximeter available for the Intellipap auto, then my decision's made -- the Autoset II.

The issue is that the Intellipap software has not been written for use with a Oximeter and can only record raw data. You still have to a separate program for the oximeter to translate the raw data.

I noticed reading my IntelliPAP Auto manual that there are indeed part numbers for the pulse oximeter that will work with the machine, however its not specified how you order this accessory equipment or what brand/model this equipment specifically is.

Here is the relevant part of my manual:



Does anyone know how to order these parts? I'd very much like to track my heartrate specifically and my O2 level as well.

Reading the Smartlink manual shows how the data is indeed stored on the Smartlink module, but needs to be exported from Smartlink to the external nVision software. That'd work just fine for me.

Thanks.

that a clue that the sensor is a Nonin pulse oximeter 8000AA about $100 amd the software aobut $310 and you may need a cable wich could drive the cost over $400

[DeVilbiss Marketing]

The IntelliPAP AutoAdjust with SmartLink will indeed interface with the Nonin Pulse Oximeter. You are correct that the SmartLink will simply record the data and the Nonin software is required to interpret the data. We are investigating the integration of the Nonin software into our SmartLink software.

[Winhack]

Has anyone attempted to implement this solution yet? I am curious as to whether I need to order the software that comes with the data cable or if I can order just the software alone.

From what I have read, this is what I understand:

1) The Nonin Oximeter probe 8000AA attaches directly to the SmartLink module (DV5M) which, in turn, is attached to the back of the IntelliPAP.
2) When the oximeter is attached, the SmartLink module will record data from the oximeter as well.
3) The data from both the IntelliPAP and the oximeter are stored and/or transferred onto the SD card inserted in to the SmartLink module.
4) The SmartLink Software (DVSSS), which is installed on your PC reads the IntelliPAP data from the SD card, but not the oximeter data.
5) The Nonin nVision Software reads the oximetry data.

I guess the real question I have at present is: Does the Nonin nVision software read the data from the SD card as well, or does it require the data cable to connect to the SmartLink Module to read its data from the source?

Unfortunately yet understandably, the DeVilbiss documention is rather unclear on how to actually integrate and benefit from the Nonin products (probe and software).

A second bonus question I have is whether or not the Nonin 8000J oximeters can be used as well as the 8000AA. The 8000AA is the reusable (the Nonin web site says only 25 uses before replacement is suggested), whereas the 8000J is a package of 25 single-use-then-discard sensors, which costs just over $60 less than the 8000AA for what appears to be the same usage value.

Any feedback would be most appreciated.
