CMS50D+ Add date and time to SPO2 file
I would assume that it is common knowledge that the CMS50D+ does not have an internal clock, thus does not write a date and time into the SPO2 file.

This lack of date and time sometimes causes problems when importing the SPO2 files into Sleepyhead.  Sometimes it works, sometimes it puts the Oximetry session on the wrong day, I find this happens more often when the session is started after midnight.

I've tested adding the date and time to the SPO2 file and was able to associate it with the correct Cpap session, previously it would either add it to the day before or the day after.

If someone is having a problem with a SPO2 file not going on the correct day because of the lack of date and time in the file, attach or send me the .spo2 file with the date, and time you would like in it and we can test it out.  This is only for the CMS50D+, and your having problems associating your oximetry session with the correct Cpap session.

After testing and it works then I'll attach the program that I made.

Interesting. I just went thru getting cms50d+ data into Sleepy Head. And nowhere was the YEAR specified!!!
Do you still want an SpO2 file ??

If you want to test it out, attach or send me one before you import it, that way you don't have duplicate Oximeter sessions for the same day.

Hello Adrinef,

I'm having the issue with .SpO2 files from CMS50D+ coming into the wrong date in SleepyHead. Adding date info to the files sounds like a good solution.  Does your offer still stand to test on one of my files and/or provide program?


Additional info:
   - Using SleepyHead-BrokenGL.exe from SleepyHead-1.0.0-beta-2-Snapshot-Win32-OpenGL-20160422
   - Using SpO2 Assistant V3.0.3 to save data from CMS50D+ for import to SleepyHead
   - Using Zeo Sleep Viewer 0.3.1 to read Zeo bedside data and save .CSV files for import to SleepyHead (that works fine).

If anyone else wants to use the program to modify the date\time in the SPO2 file, I've attached it.  

Requires .Net Framework 4

Save the zip file. Unzip\Extract  it.
Run it.
After you run the program, click the Select SPO2 file button.  It should show the date and time all 0s.  Date format is Day-month-year.
#of Samples is the number of spo2 samples in the file(read only).

Use the date box and time box to set the new date and time, then click the "Save Date and Time" button and it should write it out to the file.

Make a copy of your Spo2 files before you test it because it writes to the original file and doesn't make a copy.
