Then make sure to move the switch back to the write position so that your CPAP machine can write to the SD card. Also, make sure when you take the SD card out of the CPAP machine you move the small read/write switch on the card to the locked position so that you don't overwrite the data on the card. Note: You will need a USB SD card reader to view and import the data from the SD card into the program. The program I installed to read the SD card is called SleepyHead and can be downloaded from the following website: I was amazed and if you are the technical type that likes to view and analyze data it might help you understand and make changes that will help with your CPAP usage. He was so impressed that I thought I should give it a try to see how much more data is on the card than what my DreamMapper app on my phone is showing me. A little research and I found a program and sent the link to my nephew and he was finally able to see all of his data for the time he's been using a CPAP. We got to talking about it and I thought there has to be a way to view the data on the SD card using your computer. I have a nephew who uses a CPAP machine but pulled the modem out of it because he didn't want to send the data and have it stored on line.

They downloaded the data and the nurse went over it with me but it was high level and the details that were shared didn't stick with me.

My first instance of this was taking my CPAP machine back to my Mayo Sleep Medicine doctor at my 'Medicare' compliance appointment to make sure I was using the CPAP the minimum of 4 hours a day. The only way they learn how they are doing is by taking their CPAP machine to their doctor or medical store and have them download the data from the SD card and tell them how they are doing. Some people don't feel comfortable sharing this information so don't use the app. I use a Philips Respironics DreamStation CPAP machine that has an app for your phone and a website you can go to to view the data from the phone app.
