ResMed S9 AutoSet Questions

SD cards are hot swapable which means you can change them with the power on. However there is a slight risk of static damage and that goes down if you device is unplugged (oddly enough being on or off won't matter at all). If your the kind of person who kills laptops, phones and other electronic devices or live where you get a shock every time you touch anything, consider turning it off. Or better get an anti-static mat from an electronics supply place.

The S9 records most data internally for a while. It will only record breath by breath data if the card is in the machine when you are using it. All other data it will simply over write from time to time or when you put the card in. Leaving it in is best, but it doesn't matter much. The cards only last so long so at some point get a new one from what ever cheap retailer has them on sale. Putting the write protect on the card before hooking it to your pc will make it last longer. I'm not sure memory errors are due to putting odd mac or windows files on the card but might be that the computer writing all the files wears out the flash memory faster.

What do you mean "All other data it will simply over write from time to time or when you put the card in." It doesn't erase what the Sleep Doc or DME needs, right?

No, it's kind of like the S8 it, the card stores only the most recent 7 days of high resolution flow data and 30 days of detailed data. The card and the machine retain the most recent 365 days of compliance and summary data. So if you loose the data on the card the machine will rewrite the compliance and summary data (only). Page 10 of the manual.

Unfortunately, in my experience, very few professionals want to see high resolution or detailed data.

So do you down load the card in your computer every seven days?

charlesrshell wrote:So do you down load the card in your computer every seven days?

Well, I do it more often than that, but if it's not done every 7 days, that 7th day of info (high resolution) flow will be lost. Summary and Detail data will remain.

It's very similar to the S8 which had to be downloaded every 5 days to keep the detail data.

I never used the ResScan for my old S8, so this downloading stuff is all new to me. So are you saying you should download the SD card for the S9 AutoSet every six days instead of seven?

Charles, I've never tested it, but I think, if you want to keep the High Resolution Data, You would have to download it before noon following your 7th night of sleep since the last downloading. For ResMed products, a new day starts at noon. If you don't care about keeping the High Resolution Data, which wasn't available in the S8, you should probably download at least once per 30 days to keep the Detail data. If you download every 30 days, you will get the last 365 day of summary data, the last 30 days of detail data, and the last 7 days of High Resolution data preceding the download. This would probably be more than any health professional you're likely to see would want.

If you just leave the card in the machine and don't worry about downloading, you will always have the most recent 365 day summary data, 30 day detail data, and 7 day high resolution data available. Again, more than most health professionals would want.

OK, I guess I am going to install ResScan in my laptop today and check out things. What is that there High Resolution Data anyway?

Pugsy,

I'm wanting to try to clarify some information:

I was under the impression that SleepSeeker was an on-line program geared towards patients. I was under the impression that the info provided was about the same as what's available on the S9's LCD. But has anybody actually logged in and verified this? (I don't have an S9 any more so I can't do it.)

But I was under the impression that the on-line program that Resmed is pushing the DMEs to adopt is something called EasyCare Online. And the EasyCare Online tutorial does imply that you can generate a summary "therapy report" for folks using modems; oddly these summary reports look more like the summary pages of an Encore Report than the summary efficacy data from ResScan---there are bar graphs for each day's AHI, 95% leak rate, and 95% pressure level. But the detailed EasyCareOnline reports (which look very similar to a Rescan Detailed Data report with daily graphs) are only available if the data from an S9 AutoSet or Elite is downloaded from the SD card. In other words, the DME can't generate a Detailed Data report if the data is transmitted through the modem.

The other thing that I noticed when looking at the EasyCare Online tutorial was that the wave flow graph was NOT shown in the Detailed Data Report. I don't know if there's an option for the DME to use if they want the wave flow or not. Also the flags for the apneas that show how long they lasted are replaced by simple tick marks in the Events Table.

The fear that I have is that Resmed may be backing off making the wave flow data available to the DMEs (since they're not interested in it) and if the DMEs find no use for it, then Resmed may just drop recording the wave flow data to the SD card altogether at some future point.

And I'm still fearful that eventually Resmed will drop the SD card as the "standard" set up in favor of the modem. And only provide an SD card modem to patients who have no wireless coverage in their area for the modem to use.

Charles, check my last sentence in my post above. I was editing while your were posting, so you missed it. Basically, High Resolution allows the user to "zoom in" and examine the shape of individual breath waveforms. While this seems to be a very valuable capability, it seems to requires more understanding of physiological functions than most of us have. One can find countless threads on this forum that go on for pages and pages discussing the meaning of certain examples of waveforms. Often, it seems to me, the true meaning is never actually agreed upon.

OK, sorry, things are still a little fuzzy to me but I will learn. So every time you remove the card and then reinstall the card back in the S9, it loses the last seven days of High Resolution data only?

Charles, I don't think just removing and re inserting the card will cause it to loose data. I'm not sure what happens when the info is downloaded, I don't think it is actually erased. Think of it this way, the card has 7 places for the machine to write High Resolution data, lets call them Mon, Tue, Wed, Thur, Fri, Sat, and Sun. After the S9 fills the Sun space, it will next fill the Mon space and the previous Mon data will be lost.

There is no reason to remove the card, except to download data. If you download the data, it is not lost, it is on the computer. If you don't want to look at the data on the computer, just leave the card in the machine until you or your medical professional want to look at the most recent 365 day summary, 30day detail, or 7 day high resolution. You can continue to look at summary data on the machine as you did with the S8 and do nothing with the card, except leave it in the machine.

OK, thanks, got it.

No, that's not correct. The machine does not overwrite the existing data when you take the card out and then put it back into the machine. It overwrites the oldest of the high resolution data each night---if that data is seven days old.

An example might help. Let's say you started CPAPing tonight (June 2).

On the morning of June 3, the high resolution data from June 2 is on the card.

On the morning of June 4, the high resolution data from June 2 and June 3 are on the card.

On the morning of June 5, the high resolution data from June 2, June 3, and June 4 are on the card.

On the morning of June 6, the high resolution data from June 2, June 3, June 4, and June 5 are on the card.

On the morning of June 7, the high resolution data from June 2, June 3, June 4, June 5, and June 6 are on the card.

On the morning of June 8, the high resolution data from June 2, June 3, June 4, June 5, June 6, and June 7 are on the card.

On the morning of June 9, the high resolution data from June 2, June 3, June 4, June 5, June 6, June 7, and June 8 are on the card. Note that there are now SEVEN nights of high resolution data on the card.

On the morning of June 10, the high resolution data from June 3, June 4, June 5, June 6, June 7, June 8, and June 9 are on the card. Note that there are now SEVEN nights of high resolution data on the card. The high data from June 9 replaced (overwrote) the high resolution data from June 2.

On the morning of June 11, the high resolution data from June 4, June 5, June 6, June 7, June 8, June 9, and June 10 are on the card. Note that there are now SEVEN nights of high resolution data on the card. The high resolution data from June 10 replaced (overwrote) the high resolution data from June 3.

On the morning of June 12, the high resolution data from June 5, June 6, June 7, June 8, June 9, June 10, and June 11 are on the card. Note that there are now SEVEN nights of high resolution data on the card. The high resolution data from June 11 replaced (overwrote) the high resolution data from June 4.

In other words, each night the current night's high resolution data replaces (overwrites) the seven-day old high resolution data that is on the card. So the card always contains the high resolution data from the last seven days.

Also note: The detailed data and the high resolution data are written directly to the SD card, the summary data is stored in the machines memory. So if you forget to put the card back in the machine, you'll have the summary data for the night; it will be written to the card the next time you do put the card into the machine. But the detailed data and the high resolution data for the night are gone forever. Most docs and dmes don't really care about the high resolution data and a few missing nights of detailed data aren't going to matter as long as the summary data indicate you were using the machine as intended.

I haven't looked into the EasyCare thing at all. I know nothing about it. My sucky internet connection today prevents me from loading the videos.

I thought I had tried SleepSeeker but can't remember.
Probably I didn't. I see that they want a lot of personal information when signing up that I probably didn't want to give them.
Here's an example below that I had snagged from somewhere of what it shows. Isn't mine though. My AHI is never that high and my leaks aren't that high either. It was enough that SleepMapper was a PITA wanting to phone home at inappropriate times and didn't want to leave my computer easily...I don't want SleepSeeker app. So I really don't want to experiment with it and my S9 Adapt.

I do understand your concerns about where all this may be leaning towards...cutting us out of the picture in terms of viewing our own data. I don't know if it will come to that or not. I suppose it might but I don't foresee that occurring anytime soon. Though it does make me wonder what the S10 models will do or not do when they ever get released.
