System One bipap auto not saving waveform

[victormiller]

This morning, as usual, I uploaded the data from my smart card to see how I'd been doing. However, unlike every other night there was no detailed waveform. When I looked at the files on the smart card, for last night's therapy there was no "005" file. There's plenty of room on the card (only using 1.8 MB, and the capacity is 1.8 GB). Has anybody encountered this before? Any suggestions as to how to fix it?

How interesting you ask this question. I noticed, not last night, but the night before that I was missing big chunks of the waveform.

I wonder if there is some underlying bug not necessarily in the machine but in the SW that is manifesting here? I get all the full summary and pressure reports but missing the waveforms

This morning the waveform data was back. One extra piece of information: when I read the data from the smart card the day before yesterday I neglected to check the box which says "return the card to the patient". I'm not sure what difference that makes, but it probably records some information on the card. Maybe that said not to record the waveform. I did remember to check the box yesterday, and I got the waveform.

this is interesting - I started a nearly identical subject just the other day. My sys1 cpap pro sometimes records waveform, sometimes not, which is annoying. If I check it every day, it seems to be there, but not if it sits in the machine for multiple days.

This strongly implies that the machine ALWAYS writes the data, but then "sometimes" deletes it if nobody reads it out that day. Yet I haven't seen anything in the computer software, or machine options, to overtly control that.

The last couple days I experimented with popping out the SD card and putting it back in to simulate it being taken out - no joy, it still didn't retain anything but the most recent day.

The box that says "return the card to the same patient" is probably a good guess for the next thing to check, I probably haven't been consistent about that.

I initially was using one of my own SD cards and I wondered if respironics had created a bug on purpose so you'd use theirs... they certainly made us buy proprietary smartcard readers before... but I acquired a "genuine" respironics 2gb card and it still has the same bug.

If we can figure this out, a lot of people here will probably look forward to the advice.

one workaround that occurs to me is just to get a bunch of cheap low-capacity SD cards for under a dollar each off ebay, and mark them for the days of the week, swapping them out each morning and erasing the data after downloading from each one. That way you could read 'em all out once a week but still have the waveform data on each. It would be a kludge, but I'd be very surprised if it didn't work.. and it'd be cheap.

well, so much for my theory that the machine "always" writes the data and it can be retrieved in the morning. I just got up and read out a single night of data before 7am, and no waveform! Dang, I wanted to see that one too!

Any hints from the cognoscenti?

Hmmm...

looking at the size of the files recorded each night, there seems on quick review to be no difference in the size of the nights with a waveform printout and those without it. This should be a tipoff, because obviously the waveform report requires storage of more data. If the days without a waveform report have just as big files, it's probably "there" but being suppressed.

a PDF of some sort I found reviewing the machines on the interweb says:

"The new Patient Flow &Event
report enablesthe ability to view,
on a weekly basis, every breath the
patient takes. The Patient Flow &
Event report provides critical
details that helps accurately
identify and assess patient sleep
conditions. The Patient Flow &
Event report displays one night of
patient flow data for every 7 days
of therapy sessions and is accessed
through the Encore systems viaSD
cards or modems.Figure 6. "

This implies that encore pro chooses to only show one waveform per each week - chosen somewhat at random. Call me on this logic if I'm wrong.

Why suppress the others? I must assume that the ability to get the data every night might duplicate some other expensive machine or program that they sell, thus causing people not to buy it. "crippling" of software or hardware in this way is often done to keep from killing off other products sold by the company. I can think of no other reason to intentionally hobble a system's capability.

Victor,

Do you, in fact, have EV 2.0, and not Encore Pro 2.2?

If you have 2.0, how do you get to the waveform data?

I have EV 2.0; I've never been able to find the waveform.

I had the impression from previous posts that the waveform was available only on Encore Pro, and that EP only stores the most recent night's data.

Ok, forgive my ignorance here. What in the devil is this "wave form" we are talking about? Is that the graphs showing the Periodic Breathing and Pressure Pulses?

I've only "lost" the PG & PP graph pages when I skipped a day downloading data. When I downloaded every day I got those graphs for every day.

I hope you guys haven't "jinxed" me!!! I suppose I should knock on wood??

[M.D.Hosehead]

We know you're not ignorant, and there's nothing to forgive.

We're referring to the graphs showing the flow of air during inspiration and expiration. People EncorePro get those if they download daily. The OP was having trouble getting that reliably.

Regarding any possible jinx, if you start having trouble, you can blame victormiller and trike-mike. I use EncoreViewer 2.0 and have nothing to do with it.

Here's another interesting data point. The night before last I forgot to put the smart card back in the machine. So I expected that any report from that night would be lost. I put the card back in the machine last night, and when I looked at it with the Encore 2.2 viewer this morning it had a report from the night the machine didn't have a smart card! It didn't have a waveform from that night (but I certainly wouldn't have expected that). But it's now clear that the detailed summary report is saved in the memory of the machine even if there's no smart card, and written to the smart card when it's reinserted.

I am confused here!

Encore Viewer 2.0 is the only version of "Viewer" available and it does not report waveforms.
I have it and use it. It is available for sale at cpap.com.

Now Encore Pro has - Encore Pro 2.2 and Encore Pro 2.4. This software apparently reports waveforms. It is only available for download at limited sites.

If I am reading this post correctly, some people are getting waveform data with Encore Viewer (according to their equipment display and their posts). Either that or they are using Encore Pro (2.2 or 2.4) as well as Encore Viewer and getting their waveform data on Encore Pro.

Please sort me out!

VictorMiller, w/EncorePro 2.2.14.0 that only holds true for 2 nights of the graphs w/the Large Leak, Periodic Breathing and Pressure Pulse data which is what you guys are referring to as the Wave Form pages. It won't report the wave form beyond those last 2 nights.

Has anyone discovered any differences between EncorePro 2.2 and EncorePro 2.4? If so, can you tell us what they are?

That's not true. The Encore 2.2 viewer has the wave forms for most nights for the last two weeks or so (that's how long I've had the Encore viewer). Last night I came across another limitation: I was very tired last night, and started my APAP around 11:15pm. I awakened a little after 5am because the hose from my headgear (Mirage Swift Nasal Pillows) had disconnected. I turned off the machine, stopped in the bathroom, and then connected it again. I didn't awaken until 8:50am (fortunately my job has very flexible hours). When I put the SD card in my computer and read it in with the Encore 2.2 viewer, it had two adjacent periods -- one of a little over 6 hours, and another a little over 3 hours. The summary report looked fine, but the waveform report started at 1am. I looked at the files on SD card and it had saved two '005' files (those are the ones with the waveform data), but perhaps the Encore 2.2 software will only produce around 8 hours of data.

Victor,

Do you, in fact, have EV 2.0, and not Encore Pro 2.2?

I have EV 2.0; I've never been able to find the waveform.

I have the Encore Pro 2.2.
