I just finished testing over 20 overnight pulse oximeters against a $1,500 hospital grade pulse oximeter. Here's all the data!

The problem I've had with my Wellue O2Ring is that sometimes I put my arm behind me while I'm asleep (I sleep on my side). If I do that, it impairs my circulation and the ring registers a very low SpO2 which is for sure local, affecting only my arm. So I can't reliably get data on my overall O2 leve

Continuous Blood Oxygen Monitor?

I use a cheap Wellue/Viatom Bluetooth clip-on oximeter. Mine cost around $20 from Amazon. There are several that are known to work with OSCAR: https://josepheoff.github.io/posts/morepulseoximeters The biggest positive is that they are cheap. All are available for $30 or less. The biggest negative is

What should I be looking for with Wellvue 02 Ring Data?

I'll be honest, but this is just my experience. For me Wellue O2 Ring vastly underestimated my ODI. I kept feeling worse and it kept giving me high scores; I taped it onto my thumb, but same thing. It has a "smoothing" algorithm I have read. But whatever that does it did not feel like a reflection o

Sleep doctors don’t know about the Nonin BLE 3150 pulse oximeter

Interesting. I used to subscribe to SleepHQ to use with my Wellue O2 rings (I own both ring versions). Got tired of paying $15/month when OSCAR is free, plus the Wellue rings have poor accuracy when I compared them to FDA approved pulse oximeters. I can confirm I lost access to the O2 data on SleepH

The Wellue O2 ring is about 81% accurate? If that's true Im going to have to check out that Emay sensor...

pulse oximeters

I use a cheap one - intentionally. Everyone recommends you go with an expensive O2 ring. They are supported by OSCAR and other programs and are well known. I use the cheap one because I wanted something to be available to people who can't afford the expensive O2 rings. I bought a few cheap ones and

Sleep Trackers Wildly Different

I have a Fitbit that I've used for years. Since starting PAP therapy about 18 months ago, I've gotten a Wellue O2 ring (which says it will track sleep stages if you pay a monthly subscription) and some sleep earbuds that also claim to track sleep stages (also at least one phone-based app). I used th
