Want to see all the data stored on your CPAP machine's SD Card?

Posted by John, Volunteer Mentor @johnbishop, Nov 1, 2018

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. Some people don't feel comfortable sharing this information so don't use the app. 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. 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. 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.

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. 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. 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. 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. 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.

The program I installed to read the SD card is called SleepyHead and can be downloaded from the following website:
http://sleepyhead.jedimark.net/

Note: You will need a USB SD card reader to view and import the data from the SD card into the program. 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. Then make sure to move the switch back to the write position so that your CPAP machine can write to the SD card.

Anyone else out there in CPAP land tried this and have any tips on how to use the data to improve their sleep?

Hello @p2222, Welcome to Mayo Clinic Connect. Thank you for sharing the information with us. I still use SleepyHead once in awhile but too much information for myself. I mainly focus on the AHI numbers and how to keep them at my target number of an AHI of 4 or less. It's easier for me to understand.
How about you – do you use OSCAR to read your CPAP data? What helps you with the data?

Hi

I've used Oscar to view the information on my resmed S9. I showed the data to a CPAP technician but she said she wasn't allowed to relate to it since it's "not reliable". So I managed to install Rescan (Resmed's software) and it shows me the same summary data as Oscar….
But at least if I send that data to the technician she should look at it.

Hi @gramps, I'm sure the "not reliable" refers to the fact that the CPAP technician did not download the data directly from your CPAP machine. I asked my sleep doctor if I could just bring in the SD card for my follow up appointment instead of lugging the CPAP machine to the appointment. He told me the same thing in different words. It's kind of ridiculous but I think they want to make sure it's your data coming from your CPAP machine.

Hi @johnbishop , I think you give my CPAP techician (who is a salesman for the vendor) more credit than I do. 🙂
To get the data out of my machine, the technician needs to remove the card. When they say "not reliable", I think they want to force me to come to them for diagnosis etc., by telling you that only their software (which isn't as easy to get or use as Oscar) is reliable. Going back to them every time increases the chances that they'll push me some other piece of equipment.
But maybe I'm just too cynical….

@gramps, I'm not sure this is helpful but I did find a ResScan Interpretation Guide for ResMed.

@lisalucier I haven't had the chance to spend any time going through all of the data yet to figure out what I can learn from it. I listed the currently supported machines by SleepyHead in the discussion description above. Here are a few screen shots as a teaser. There is also a frequently asked questions and a user's guide you can access from the programs help menu. Here's the link to the user's guide.

http://sleepyhead.sourceforge.net/wiki/index.php?title=SleepyHead_Users_Guide

I'm thinking I need to go through the user's guide first. Being somewhat techie I normally only use them when I can't figure it out using the program.

@johnbishop Do you know how to get the program to give you a column about 4 hour usage in the statistics? I have looked all over both Sleepyhead and OSCAR and I cannot find anything. I need to print out a report for my husband for his job and they only want to see the 4 hour usage and nothing else. Any help would be greatly appreciated.

Hello @jesskpicone, Welcome to Connect. I mostly use the MyDreamMapper program that comes with my Dreamstation CPAP machine. If you have a similar program and can display the daily hourly usage on your computer you could take a screen shot and print it out or paste it in a Word document. I think they are just looking for compliance that your husband is using it at least 4 hours a day so a screen should satisfy their requirements.

Also, I think you can export the data but I'm not sure of the format. It will probably be comma separated which you could put in a spreadsheet that shows the hours used on a daily basis. Here's a good YouTube video on how to use SleepHead: https://youtu.be/FMkBatUVu7s

@johnbishop @gramps, Hello I am new to this and just joined the Mayo Clinic Connect. My dilemma is the following: I am getting all my requirements needed for my bariatric surgery. One of them is the compliance for my sleep apnea. I have to be 75% in compliance within a 30 day period. I had major issues with face mask not fitting properly. Had to go twice for fittings since November 2020. Because of this I was not using my machine. I have anxiety issues and tend to wake up and pull the mask off my face. Well I was using the full face mask that had a lot of leakage. In November he sent me home with the pillow that goes under your nose and but covers your mouth. That didn't work for me. Had to pull the straps as far as they went to not get air leakage. So I went back and now i have two options to try out. Both are nose pillow mask. So I must make sure I keep my mouth closed while sleeping. So because all of this back and forth I had to start fresh for my 75% compliance. Start date was Jan 26th. I have the same problem @gramps has. My modem isn't working and I'm ok with that. But I have to take my machine so they can download the info from the SD card. If I use any of the two options…OSCAR or Sleepyhead to view my info will it delete it from my SD card. I don't want to mess up my 75% compliance stats. But I also want to make sure I can view it and if I get there before the 30 days I would like to let them know. I hope I make sense. This is all so new to me. Thank you for any advice given!

Hello @delilahrose, Welcome to Connect. When you take your SD card out of your CPAP machine just make sure you set the read/write switch on the SD card to the lock position so that the data cannot be erased and lost. Then you can put it in the reader and upload to OSCAR or Sleepyhead. Then just put the switch back to the unlocked position when you insert it in your CPAP machine.

Sorry to hear you are having issues with the mask. I use a ResMed AirFit F20 full face mask with a cloth Comfort Cover. It does have a little leakage but that really doesn't hurt compliance – https://cpapcomfortcover.com/.

Have you considered using a chin strap to help keep your mouth closed?

@johnbishop Thank you for your response. This last time I went to get mask fitting he did show me the one you are currently using. It was to big. He said fitting me was difficult because I have a small face and even smaller nose. So he sent me home with the AirFit P30i and the AirFit N30i. I am currently trying them both to see which one I am more comfortable with. I like them both but my nose gets super dry and I do have issues with bloody nose on left side only (for many years). I am just hoping i reach compliance before the month end. Which is why I want to check this myself. I don't want to go to hospital with machine in tow every time I THINK I am at 75%. He also gave me with a chin strap. But I have no issues with keeping my mouth closed when I sleep. I would definitely know if I didn't since with this type of mask you must have mouth shut. Last night was a good night…I did 9 hrs with AHI 4.1. I do remember waking up 3 times removing my mask because it was getting to dry. That's the real issue I have now. Any suggestions?

@delilahrose I have dry mouth once in awhile also. What helps me is Biotene mouthwash – https://www.biotene.com/dry-mouth-products/mouthwash/. I think you can get it at most drug stores or supermarkets as well as online through Amazon. The inside of my nose also gets dry and I use a petroleum free CPAP moisturizer like this one – https://www.amazon.com/RespLabs-CPAP-Chap-Face-Cream/dp/B01IOE876W/ref=sr_1_3. It also seems to make breathing through my nose a little easier.
