[Equipment] SD cards

[starbird]

Can I purchase a regular SD card for my Resmed (for her), or are there special ones for the machines?  My new machine did not come with one because I was told by the supplier that since it has a modem it didn't need one, but I can purchase one if I want.

Hi starbird -

Any SD card 32 Gb or less will work fine.  So the answer to your question is, "Yes".  The SD card actually holds a lot more detailed sleep information than what the modem transmits.   While you are at it, pick up a free copy of #SleepyHead.  The download link is in the name.   #SleepyHead will provide a detailed insight your sleep parameters and treatment settings.

Good Luck!

The ResMed OEM SD card is 2GB, you won't find one.  The good news is any SD card <32GB will work. 

You only NEED the SD card if you want to see detailed data.  You definitely want to do that.

Download and install SleepyHead to do that, it's free and it is the best software available.

I replaced the SD card in my system one with a larger card.  Any SD one should work but there is a max size it will handle. Check the manual.

The ONLY difference between the routinely available SD cards and the manufacturer's sanctioned cards is that the specifications of the manufacturer's suggested card have been provided to the FDA and judged to be suitable for use in a medical device -- as a function of manufacturing quality control, capacity, speed, and actual testing with the recommended device.

Since it is unlikely that the data capture is life-threatening critical and you are willing to accept the potential loss of data should the card fail (most unlikely), any card that is on the manufacturer's list is acceptable. Here is what RedMed has to say about the cards in their S9 series https://www.resmed.com/us/en/consumer/su...-faqs.html. The article contains a telephone number and an online contact link to request further information.

I have seen the ResMed branded cards for $15 (plus postage) so ask yourself is it worth it to save a few bucks for a critical component -- especially when you can get it under warranty from ResMed. For those on insurance plans, you might wish to ask your carrier or DME if a failed card is covered.

You can get a standard SD card from Resmed ($$). The machine specs indicate that SD or SDHC cards will work. A typical SDHC card with lower capacity will likely be under $10. If you stick to one of the well known brands it should work just fine.

MicroSD cards with adapters have been reported not to be reliable.

It appears that Resmed does not recommend use of SDHC cards, regardless of whether they work, mea culpa.

It is possible to still buy a 2GB SD card, but the going rate appears to be $16-18.

I see a 2-GB card on Amazon for $9. Transcend brand, Prime-eligible, Amazon's Choice (which I guess means many sales and few returns).

There's no need to be concerned about the capacity as long as it's at least 1 GB; the consumption is somewhere around one gig per year. Also, it's possible to archive the card data to your computer's disk periodically, erase the card, and start over.

(Edited to add: I meant erase the card on the computer, not on the CPAP machine. If you do "Erase all data" on the machine, you'll also be getting rid of compliance data, which isn't a good idea at first. But if you put a blank card into the machine, it'll be formatted and used OK.)

The advice that any SD card will work is not quite true. It kind of depends on the age of your S9, or more accurately where it fell in the production of the S9 series.

The earlier S9s required an SD card. It will not work with SDHC cards. I tried it once when Fry's had a barn burner sale on SDHC 8 GB cards. I bought a few. PLugged them into the machine and it looked like thugs were working, but in a couple of months, I went to pull data and nothing had been written. After much searching, I found that the machines were only wet up for SD cards, 2 GB or less. They are still available, but as they are rare, they are getting pricey. Think amazon or ebay as most likely source. Expect to pay at least $10-20 each, maybe more.

Best advice? Buy the lowest priced, lowest capacity SDHC card you can find and see if it will work and you can pull data. If not, your machine, like my old one, may require a straight SC card. I don't know how to tell any other way. If anyone knows, please share.

And now that I read the other threads, I went to the ResMed reference and saw "Secure Digital High Capacity (SDHC) cards, as well as mini and micro SDHC cards, and SDXC cards, do not work with S9 therapy devices." so most cards available like at Walget or Tarmart today are no-go.  SD maxed out at 2GB, IIRC.  However, I understand some with neweer machines have seen the higher cap cards go.
