CMS50D+ detailed data

[bernardc]

The issue is how to get the detailed data, i.e. the actual data points. I can upload to SpO2 and, on some computers at least, to SleepyHead. Both appear to upload the detailed dataset, but I don't see any method of exporting it to, or saving it as, a text or spreadsheet format. Can anyone tell me how to do this?

I like my numbers in Excel also.

I export my data from Sleepyhead with the following key sequence:

File
Export data
Csv export wizard.

Whether or not the data would include CMS50D data, I can't say as I don't have one yet.

I get counts, time, pressure. I dont get leaks , resp rate, ventilation, tidal volume. To get that I have to copy and paste. I copy the summary data into Excel.

Let us know what happens, I am interested in getting the CMS50D myself.

CP,
I did try that, but it does not export the detailed data. The most I've gotten is the oximeter statistics. I think this feature in SleepyHead has not been completed as of yet.

Some general googling shows that this issue began in 2014 with the introduction of the .SpO2 file format to the CMS50D which was initially not readable at all in SleepyHead.

More promising is this GitHub project described as "A Qt application to convert from the .SpO2 file format used in some digital oximeters to a csv file." Although that project is setup for Qt, a cross-platform application framework, the C++ code looks like it could be readily ported by anyone modestly skilled in the art.

But more to the point, SpO2 Assistant and Sleepyhead both can read the file just fine. Now they need to make the CSV export available.

Here's how I got the job done. The open-source version of Qt is free. I downloaded and installed it. Then I opened the GitHub project that I mentioned in my previous post. Hit play and you get the working window shown in the first screenshot. Give it the filenames and you get the .csv file. Voila. The second image is a plot of that data with some smoothing using SigmaPlot. The datarate is surprisingly fast, 1 Hz, but integer values only. So I applied a bit of smoothing to exploit the natural dither in the data, yielding finer resolution and a much more meaningful graph.

The upshot: The DreamStation Auto BiPAP is doing its job.

I tried to put those images inline in the post using the code show at bottom, but all it shows is the word "Image." What am I doing wrong?

Not sure what you mean about address at the bottom but at this box of addresses if you hit "large thumbnail" first and then copy the last line in the box of addresses you will get an image showing in your post that we can click on to enlarge it if needed. You need to be using linked bbc code url address for the image to show up.
You have to be logged in to the imgur account to get this box after you select which image you wish to share.

Very impressive. Beyond my skills I believe.

Not sure what you mean about address at the bottom

I meant shown at bottom, meaning these two links:

Are you able to see the images when you click the links? I uploaded those without an Imgur account, and I don't see that Imgur window you posted, so maybe that's why it didn't work as inline images in my post.

If I click on the links I can see the images.
Using the image brackets from the forum editor and your address I get the word "image" also.
I don't get an image embedded in the post. Not sure why it won't work.

Yes..the box of addresses only shows up when a person is logged into their imgur account.

But using the link you posted worked.
I can't comment about what you did because I know nothing about doing stuff like that with the data.
