Having a problem with screenshots

[Sleeprider]

What is your operating system and screen resolution?

Sleeprider:  My hematocrit was 49.2% on 1/21/2019.  I has been a percent or two above 50 in past, ringing bells.  In my mind this is what led me to the sleep clinic last fall.  But no one has spelt out a relationship of polycythemia and sleep apnea.  My condition could also be exacerbated by dwelling part time (~20%) at 7500 ft elevation.

There was documented screen shot issues with Sleepyhead 1.1.0 mark fixed them in the version used for Oscar, I suggest either going back to 1.0.0 or using some other method to take the screen shot as the f12 is broken in some o/s versions

Thanks jaswilliams. I will try installing SH 1.1.0 on a Win 10 platform. I'm reluctant to go back to 1.0.0 because of the warning that my files may be corrupted by such a move.

This may take up to a week as I have a hardware issue to address and other things to do. I really appreciate the help you and others have responded with and hope to be posting soon.

Those of us working on OSCAR have found there is no problem with moving data files between 1.0.0 and 1.1.0. It has been demonstrated on a number of platforms, and no issues have been reported. In any event, a backup exists in both data directories.

Thank you,  I'll take that into consideration.  

I have a question.  You said above:

"Polycythemia, or a high hemocrit is usually a result of testosterone replacement therapy or chronic low oxygen content. What is your hemocrit/ hemoglobin count? It's not something that shows up on the respiratory graphs."

No THT in my case, but altitude was the first explanation that came to mind.  That seems unlikely however because my time spent above sea level is seasonal and my polycythemia isn't. That leaves sleep apnea as reasonably involved.  My question is what should polycythemia look like on the respiratory graphs?  Presume you mean the Sp02 graph?  What would be a SpO2 consistent with polycythemia look like?  

I have to admit, I've little prior education on this matter and haven't really thought it thru, but obviously if O2 supply is restricted then increasing hemoglobin concentration in the circulatory system improves availability of O2 first and foremost to the brain.  In this particular context polycythemia (making a lot of red cells packed with hemoglobin) is a feature not a bug.  It's a solution to a problem -- just not a very good one because it puts the individual at risk of stroke, hypertension etc. by thickening the blood excessively. 

I would be interested in knowing how common polycythemia is in sleep apnea affliction.  Do you have any figures on this?  Perhaps I'm barking up the wrong tree and my (incipient) polycythemia is a bug (ie. disease) in it's own right.

Polycythemia is documented in both high altitude residence and sleep apnea. If you search the technical articles on both subjects, you will find these are considered secondary causes for polycythemia and there is not a lot of agreement on causes or severity, and OSA is particularly doubted as a root cause. Treated OSA should not result in higher RBC and hematoocrit counts. The most common cause is dehydration, but smoking, apnea and high altitude are all potential factors.

I had similer issues taking screenshots in SH. I resolved it by: instead of using f12 I hit “print screen” then use the photo editor of my choice to paste the screenshot into a new image and save.

Thank you ruthcatrin and all who have responded to this thread.  I finally decided to risk it and go back to using SH 1.0.0 .  So far all is well;  no sign of data corruption (will post if I detect any) and I'm able to take screenshots (F12) as before I updated to SH 1.1.0 .

My problem and tentative solution (back to 1.0.0) is for the OSX platform using v. 10.11.6 .  I don't know if screenshots function in v. 1.1.0 on other platforms (but assume they do on Win10 or imagine we would have heard about it.)  I would suggest that the recommendation to download SH 1.1.0 be qualified in some way.

PS:  If anyone is interested in the polycythemia topic discussed very briefly here, I've moved my CPAP discussion to the Main Board.  The thread is "A Lost Cause?"  and hopefully we will return to polycythemia there.
