Got questions about device data cards, and what SD cards can be used with your device? Find the answers to your most frequently asked questions about device data here.
Q. Which SD cards can be used with S9™ therapy devices?
A. The SD cards we recommend are those supplied by ResMed with the S9 therapy device, or available as an accessory.
Q. Why do you recommend using only ResMed supplied SD cards?
A. ResMed-supplied SD cards should be used in order to meet safety standards (e.g. IEC 60601-1). The electrical safety test authority has determined that S9 therapy devices that use SD cards need to have appropriate clearance from the accessible part of the card to the electronic parts inside the card. ResMed has selected several SD cards that meet the necessary safety requirement and supplies these with the therapy device or as accessories. Not all SD cards on the market meet the clearance requirement or have been tested and validated to work with S9 devices.
Q. How much storage does the S9 therapy device use on the SD card?
A. A 1GB SD card easily stores 365 days of usage data, 30 days of detailed data, and seven days of high-resolution data.
Q. Can I use miniSD or microSD cards with my S9?
A. No. While these SD cards, used with an adapter, would work with an S9, they have not been shown to meet the IEC 60601-1 medical electrical equipment safety requirements for this therapy device. As a result, ResMed recommends that they shouldn’t be used.
Q. Can I use SDHC, mini SDHC, micro SDHC, or SDXC cards with S9 therapy devices?
A. No. SDHC cards, as well as mini and micro SDHC cards, and SDXC cards, do not work with S9 therapy devices.
Q. Which SD speed classes work with S9 therapy devices?
A. The SD Speed Class is marked on most SD cards. Class 2 has a guaranteed transfer speed of 2MB per second; Class 4 achieves 4MB; and Class 6 provides 6MB. Note that only ResMed-supplied SD cards should be used.
