I'm glad you're back up and runninggpk111 wrote:Good thread. I just got my S9 and jumped right in to analyze my data by pulling the SD card out of the S9 and loading the data onto the ResScan software. Thanks to all who helped me get out of trouble, since I used my camera as the SD card reader. When the camera wrote something onto the card, the S9 wouldn't read it. Forgetting about my adventures, though, let's step back and discuss design objectives. Here are some speculative points for comment:
At the moment this is unchartered territory. Unfortunately I'm not willing to try this as I don't want to my data. My guess is however that if you don't have an SD card inserted that it might keep up to 30 days detailed data in memory, but could be more likely 7 days seeing that the S9 deletes detailed data > 8 days old automatically on the SD card.gpk111 wrote:1. Assuming you have no SD card plugged in, how many days of detailed data does the S9 hold? Hard to believe it's only 7 days???
That's interesting, I hadn't seen this before, but I can understand why it would do this. I presume by OFF you mean that the display has gone off? Rather than having the display ON but you've just powered it off so you don't get any air?gpk111 wrote:2. I discovered that the S9 automatically loads the last nights data onto the SD card after the machine is shut off.
Correct, if the data has been loaded onto any SD card it doesn't seem to write data to a newly inserted/formatted card.gpk111 wrote:3. IMPORTANT: I also noted that it only loads data onto the SD card which hasn't been transferred already. That is, if yo decide to put a new SD card in, you get nothing but the new data. Therefore, try to keep all the data on one card.
Ultimately this is the best way to do it, and although ResMed could have gone with a MicroSD card slot, I'm glad they went with a Full SD card slot as MicroSD cards you can't write protectgpk111 wrote:4. Lesson learned: Lock the SD card before feeding it into any reader. If you then unlock it before putting it back into the S9, you should be good to go.
If you don't have the SD card in then I'm not sure whether you do or don't get the detailed data. You should definitely get the Summary data, maybe someone is willing to give this a test and see?gpk111 wrote:4. I assume all prior data stays in the S9. However, any future data is also copied to the SD card. It needs about 3 MB per day. That's a year of data on a 1 GB card.
The problem is that even though the machine will store up to a years worth of data on the SD card it's only Summary data, so after 8 days the Doctor can get at the Summary data, e.g. AHI, AI, HI, Central, Duration on machine per day etc, but can't get at the Detailed data. You can resolve this by manually keeping a folder on your PC that takes the latest detailed data and create a DATALOG folder with all your detailed information in if you're concerned about this.gpk111 wrote:5. Given all that, I guess the machine is designed to provide info for a doc at say 2 month intervals. Therefore the card is needed if the machine only holds 7 days of data.
That's easy, open up the PATIENT MANAGER screen and it tells you where the PATIENT folder is on your hard disk. You can back this up reguarly.gpk111 wrote:6. If someone uses the RESScan software (not bad, by the way!), rather than depending on their provider for periodic printouts, it would be nice to know where the data is and how to back it up.
As with (Q6) - just backup that folder, install ResScan to another computer then overwrite the Patients folder with your backed up version.gpk111 wrote:7. Questions: The ResScan software seems to do a good job of collecting the data from the SD card and adding it to the prior data set. Where is that data and how can it be backed up so that ResScan can read it if a hard drive crashes? ..or does the data have to stored on a drive in pieces and then loaded onto an SD card to be read by ResScan?
