OSCAR and 02 ring for shift workers

[offline]

Hi. 

Say if I go to sleep at 9am and then wake up after 12 noon, the 02 ring data (both pulse and spo2) does not appear for any of the afternoon hours on my setup. 

I use Oscar 1.3 for MacOS.Monterey 12.01

I use ViHealth for Android (tried both the special version V2.630602 and the latest version.) and upload files from that to my macbook. I do not think it is the data itself.

This worked before with the earlier version of OSCAR.

Anybody have the same issue as me?

Are the dates and times between your computer and Ring synced up?

Have you tried changing the time/date in the oxi file to match what OSCAR says is your start time?

In order to help with your problem, I need more detail as to the method you employ to address sleeping through a CPAP day change. Are you setting your CPAP's clock back, or what?

Hi Jeff8356, yes they are synced up (at least within 7 seconds which is the best I can seem to get.) No I have not tried altering the filename yet. Thanks I will try this.

Hey Crimson Nape. I am not changing either my CPAP clock or Viatom device settings other than to make sure they are as close in sync as possible.

I am still investigating this. My last sleep sessions worked perfectly ok I believe because a) one finished at 8am in the morning (so before 12 noon) and b) one started after 12 noon (at 12.40pm in the afternoon.)

It is summer where I am at and I have adjusted for daylight saving.

What I will try to do is simulate a sleeping session or two to confirm my suspicion which is if I sleep through noon at any stage, OSCAR is confused because the CPAP considers sleeping after noon to be a new "nightly" sleep session. In the past the oximetry data was still there, now it seems to go missing.

I'll do some tests to confirm and then post back. I am still considering the possibility I am at fault here.
