[OXIMETER] first night with Wellue Checkme O2
[OXIMETER] first night with Wellue Checkme O2
Finally caught a great sale on the Wellue Checkme O2 Max.  Bought on Thanksgiving day and delivered yesterday (11/26).  Installed the ViHealth app on my Android and O2 Insight Pro on my windows machine.  Pulling the data onto Android was easy, but screen too small and not integrated with OSCAR. Thanks to apneaboard I was able to pull the data from the checkme onto my windows machine into a directory I created and then import that file into OSCAR.  Worked perfectly!

The night spent with checkme was quite interesting.  I had the O2 minimum set to 90%, which is the default, and it began buzzing my thumb around 1:42AM.  This  occurred after waking up and rolling over to my left side. I buzzed for a minute or so and stopped when I rolled back over to my right side! After rolling back and forth I determined that it wasn't positional as it occurred on both sides. Took awhile to fall back asleep only to be buzzed awake around 5:45AM.  I finally I took it off around 7:11 because it kept buzzing.

Was anxious to see if the O2 issues correlated to CPAP events, it didn't as far as I can tell (see screen shots).  My AHI was .28 with very few events:


I zoomed into a section that had low O2 to see if there was any correlation to CPAP events:


I couldn't see any.

Any insights would be helpful as low O2 seems to be an intermittent issue.

BTW, I noticed that my shallow breathing would trigger low O2 within 5-10 seconds that didn't show up as a Air Sense event.

RE: [OXIMETER] first night with Wellue Checkme O2
In my case, my main drops correspond to sudden onsets of brain+body consumption rate - eg due to degrees of physical movement, especially if part of REM stage (whose signatures one can learn to recognise, eg basics learnt from Youtube vids on "sleep staging"). So I feel comfortable in ignoring those. Other people's situations might be different.
