Power down to remove SD card on S9?

jhensley · Post by **jhensley** » Sat Jul 30, 2011 11:13 am

Is it necessary to power down or unplug a ResMed S9 before removing or inserting the SD card? I know it seems like a small thing but I'm new to this and like to review the data every morning to see what I can learn while the last evening is still clear in my head. (For example I've reduced my events significantly by sleeping on my side. I'd always thought sleeping on my back was best.) If I power off or unplug the cooling down process is interrupted.

Nope. You can insert and remove it with the S9 on. Probably best not to do it while you're actually using the machine, though, because in therapy mode it will be writing to the card frequently.

The clinician manual says to power down before removing card. I always do this, then insert card and power on once downloaded. The machine does a restart, I can always tell the card is properly inserted and I have not had the data skew, that some here have reported. Dan

I unplug--not taking any chances with Precious.

It does?

S9 Autoset Clinical Manual wrote:Removing the card
Instruct the patient to:
1. Push in the SD card to release it.
2. Remove the card.
3. Insert the card into the protective folder.
4. Send the protective folder back to you as instructed.

Inserting the card
1. Remove the card from the protective folder.
2. Push the card into the S9 device until it clicks.
3. The following message is briefly displayed: Reading SD card
Notes:
-For more information on removing and inserting the card refer to the S9 SD Card Protective Folder provided with the device.
-Ask the patient to retain the S9 SD Card Protective Folder for future use.

Turning the machine off is a good idea. Unplugging it is probably not a good idea.

Once you turn the machine off, wait a minute or two before removing the card. It might be writing data for a while once you turn it off. You should also not unplug the machine at that time.

On PRS1 machines, the display says something about waiting to write data to the card when you turn it off. Does an S9 machine say something similar?

Yes it does ! Page 27 of clinician manual for Resmed s9 Vpap. Actually, someone questioned unplugging, and this is what it says!

Removing the card
Before removing the card, instruct the patient to
disconnect the VPAP device from the power outlet.

Interesting, the S9 Autoset Manual does not say that. It does support unplugging the machine, though.

S9 Autoset Clinical Manual wrote:In order to assist the heater plate in cooling, your S9 device will continue to blow air for up to an hour after treatment has stopped. However, you can unplug the device from the power outlet at any time and allow the heater plate to cool without air flow.

That is the only use of the words "outlet", "plug", "unplug", "power", and "cord", except for descriptions of the components, the instruction to plug the machine in when setting it up, and the usual safety warnings:

S9 Autoset Clinical Manual wrote:
-Do not connect the power cord to an electrical outlet while both you and the S9 device, H5i docking station, power supply or power cord are in a salt water aquarium.
-Do not unplug the power cord partway from the wall outlet and attempt to lick the metal parts of the plug.
-Do not insert the power cord plug partially into a power outlet and attempt to lick the metal parts of the plug.
-Do not remove the tag from that power cord that bears the words: Do NOT Remove This Tag
>In the event of power failure or machine malfunction, remove the mask. [That one actually is in there.]

It's probably a typical modern corporation. Give some moron who can't do any real work the job of writing the manual. The moron is afraid of his own shadow so he makes up all kinds of "better safe than sorry" warnings.

Either that, or they're trying to scare the patient into being afraid to do anything with his machine.

I talked to a friend last night and was telling him how he could find out a lot of info from his machine and he was afraid to do anything at all with his machine because the doctor or insurance would get him somehow.

I have just been pulling the card out and putting it back with the S9 plugged in, seems to work fine. That said, the clinician's manual does say to unplug it first. Note that if you follow the directions in the manual exactly, they never said to plug it back in and in fact the insert card instructions imply that you do that with it plugged in.

Thanks for all the input. Good information. It appears that different ResMed publications contradict each other.

The reason I'm concerned is when I remove a SD (or CF) camera card thats connected to a computer without unmounting it, I always get an error message that says something to the effect that the disk was not ejected properly and data corruption could result.

Any thoughts on when the S9 writes to the SD card and how long it writes after completing treatment.

Arrrrrgggghhhhh! Don't tell me Resmed is going the way of Respironics w/their asinine unplug, plug in to get some of the basic info on the LCD screen such as total hours on device, etc. that you had to do w/the pre-M Series and M Series!!!!! *sigh*

That would seem easy to test. Just make sure the clock on the S9 is set correctly, then note the time you turn it off. Then when you have the SD card in your PC browse the contents and see what the time stamp is on the newest data file.
