Sleepyhead Question

Greetings all New CPAP user and have downloaded sleepyhead to take a deeper dive into the data. I have a Resmed Airsense 10 autoset and the Resmed Airfit F20 Mask. I understand I need to lock the card before inserting into my Macbook. I assume the data will remain on the card and it will continue to record new data after reinserting to the machine, correct? Also, for some reason there is no SD Card in the machine so I am assuming any recent SD Card will work. I would imagine that data isn't to large and a 4-8 GB will work.

Also, If I get a new card, will it write the data which has been recorded (4 nights) to the new card and everything will be hunky dory from there?

Thanks for the help all

The warning to write protect/lock the SD card is mainly for ResMed S9 users. Your model machine won't care if an operating system writes a little text file to the card but you can lock it if you wish and if you forget (I do and I have a S9 ) it won't hurt anything.

Yes, any SD card will work and actually 2 GB is plenty big but those are getting harder to find so you will likely have to go a bit bigger.

The only data that is stored on the machine is the summary data...just some numbers and no graphs but what is stored will be written onto the SD card when inserted in the machine. So you will be missing some of the graphs but as soon as you start using the machine at night with the SD card in your machine those graphs will also be there for you.

Just remember the SD card MUST be in the cpap machine while it is in use to get the graphs and detailed data.

SleepyHead doesn't remove anything from the SD card so any old data stays on there. The warning about write protect comes about because some operating systems (some Mac and Windows 8.xxx and higher) will write a little text file to the SD card and while it hurts nothing the ResMed S9 machine didn't like that text file being on the SD card and it would tell you that the card was invalid. It's fixable even for us S9 users if we forget but you won't have that worry with your AirSense machine.

Thank you very much for the insight Pugsy!
