[Contec CMS 50F] Confusing Sp02 & pulse rate pattern - Bug?

[Contec CMS 50F] Confusing Sp02 & pulse rate pattern - Bug?
Hello guys,

I have been requesting my mum to check her Sp02 & pulse rate, hence she also bought a Contec CMS 50F and tried it yesterday night.

Attached is what came out, and the results look a bit confusing to me... Have you ever seen this pattern before?

The lowest oxygen saturation goes down to 89% during the drops. I told her to try again tonight and cut off Bluetooth/Wifi etc that could interfere in the bedroom, and we will see the results again tomorrow.

However she has run tests in the afternoon for like half an hour and everything was fine on Sleepyhead so... Any comments will be must appreciated ! 

Thanks

Thibault

Looks like the same oxygen drops I get when I have apneas. Does she use a CPAP machine? If so, would need to check the logs with sleep head software and see if she was having obstructions at night. My oxygen dips like that to 80% then right back up when your body momentarily wakes you to try to breathe again.

Notice how the heart rate jumps a little up after the oxygen dropped. That usually happens when someone has apneas. Your heart rate will rise to try and get more oxygen since you are suffocating basically. My heart rate does the same thing.
