S9 - Disappearing Flow Data?

[DreamDiver]

I carried out a test (thankfully I've made a full backup of most of my day's SD cards just in case something went wrong) - call my cynical

Here's the default from my early import then importing my newer SD card backup from last night and choosing DISCARD. You still get the full amount of days worth of data imported and you do retain the FLOW graph.

dave21 - thanks for figuring this out. This is awesome.

Ouch! Sorry that happened. Will you have to start over, or is this in a new separate patient?

Nah I did it in a new 'test' patient profile so I could observe the results and not mess up my main patient file

The 'discard duplicate data' method seems to have left the data from the 9th on my computer. I have nine total days of flow data so far. We'll see how it goes. That particular dialog box could probably use rewording. It really isn't duplicate data if the flow data is deleted regardless after seven days.

The next thing I guess I should try (and this might be a better way) is to just backup the data folder from ResScan and see how easily that's restorable providing you use the same version of ResScan software. That might be a less hassle method of ensuring a backup and you can have an automated backup application doing this for you on a weekly basis. The only downside with this is if you had to send your SD card off to DME/Doctor/Manufacturer then you lose your detailed data > 7 days.

EDIT: I just looked around. I don't see any method for full data backup of all data on ResScan. That's a serious problem. There appears to be nothing about it in the 3.10 clinician's manual either. Double Ouch.

I think 7 days isn't enough personally, what happens if you have been having problems for a week or two and your doctor wanted to look at your stats. They'll be able to access your summary data off the card but not the detailed data. I would have thought it would be better to keep detailed data for say 3 months or 6 months. Even at 6 months (3.10 mb per day), it's only 558 mb (half the card size. Surely that would have been a better setup and then purge data older than 6 months?

I think it's good we all know this limitation. For maybe the average patient loss of the detailed data might not be much of a problem, especially if they're compliant, but for us that want to look over our data every day I think it's best we know the pitfalls and limitations so we can work around them

I agree - there should be a clinical setting on the machine and in the ResScan software that will allow the defaults to be changed to fit larger data cards and multiple longer periods of full data. You're right - the default card capacity is huge compared to the data it stores. Why would ResMed only use part of the card? Imagine from the point of view of a clinician though - who wants to wait all day for someone's data to download?

I can tell you this will work... I moved the computer ResScan was running on to a different one and did this to copy the data over--all my data was still there and in-tact. So, backing up the patient folder should be a reliable method keeping in mind that the Summary data is all stored in one file (the detailed ones all appeared to be separate for each day).

Somebody asked in another thread whether there would be more data stored on a larger SD card and it's entirely plausible that ResMed might be using percentages instead of fix numbers for days, so on a larger card it might keep more data but we'll only know if we try it for sure. i will switch to my 16gb card and see what happens over the course of the next week.

That's great, thanks for confirming jmelby! In that case it should make life easier, just get a freeware or shareware backup app that allows you to backup files (simply copy) to another folder on another drive and version it into different folders would do the trick.

There is no limitation. If you transfer the data from your flow generator to ResScan regularly you can hold years of cumulative data on your computer in the one patient file, and back it up, restore it, copy it to a new computer, etc, quite freely.

This has been covered numerous times here over the years since ResScan was introduced.

Why not just backup the entire Patient folder? That's what I do and have restored that when I set up Resscan on a new computer.

[dave21]

Backing up the entire patient folder is okay, but it doesn't work well under Vista. Vista it shunts all data folders into the \Users\Public folder, e.g. C:\Users\Public\Documents\ResMed\ResScan3\Patients\ so you can't easily back this up. I use Windows Live Sync to sync folders between computers and it won't let you touch the C:\Users folder because it sees it as a private folder.

So I'll have to manually do it if I want to do it this way

HOW do you load the files from a backup directory? I took a copy of my SD card and put it on a USB stick. Then I tried to load the data from that USB stick and I was told "attach SD card or flow generator". How do I get ResScan to read from the USB Stick?

I just messed up this post trying to edit it! See new post later.

When ResScan is on, it has a systray listener called 'CRWS'. Double click on the systray icon and you'll see the above 'about' box. CRWS.exe checks about once a minute for any SD card or smart card that's attached to the computer. If the correct identification documents exist on the card, it will attempt to connect to ResScan. I suspect the data may need to be on an SD card of your choosing, but it must be an SD card. A regular thumb drive doesn't plug straight into the S9. Hence, it will not be recognized by ResScan as a valid port because the listener isn't set to scan thumb drives - only SD cards and smart cards for the S8 series. If you have a USB SD card reader you're using like a thumb drive, it should still be able to validate whether the SD card has documents that ResScan likes.

I haven't tried it, but you might consider right-clicking on the systray icon and forcing it to 'Check A:/B: for card data'. It probably won't work, but you could give it a shot.

FYI, once you quit out of ResScan, the listener also quits.

Good luck.

I run Resscan on my desktop as well as on my laptop.
My laptop has no SD-slot and I don't have a card reader.
I copy all files from the Resscan SD-card straight to a USB-stick, and Resscan recognises the USB-stick without hesitation.
Don't ask me why, but it works.
One big pro, the USB-stick contains allready about a month high-res detailed data, so it works as a backup as well.

All I keep getting is:


The USB stick has the same layout as the SD card.... I guess I am going to have to try another SD card rather than the USB stick.

Rescan 3.10 on my laptop won't recognize a USB memory stick either...

As an experiment I simultaneously inserted one blank SD card and one blank USB memory stick. Then in ResScan I went to TOOLS==>DEVICE SETTINGS. When I clicked SELECT DEVICE I saw that the blank SD card was available for selection, but the USB memory stick was not.
