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

These posts are truly so depressing and common! Who are all these men out here thinking they're gonna fistfight Death and that breathing is for wimps? If he already knows the Jo Koy routine, my guess is recording the sound won't help. He thinks he's tougher than Shaq and Brett Favre, both of whom us

To measure SpO2 at high resolution, you need a device like Wellue O2Ring-S. It records SpO2 & heart rate every second. There are other options but this is the most comfortable form factor to wear IMO. I upload my CPAP data and O2Ring data into OSCAR (free open source software) to analyze my breathin

Hello all. I have a new diagnosis of mild sleep apnea that I wanted to try to improve without CPAP via weightloss and a mandibular advancement device. My diagnosis was pretty mild (AHI 11) w/ majority supine. I am a very data driven person, so in order to track if these interventions were doing anyt

I use the Wellue O2 ring that does every second. It imports into OSCAR and SleepHQ, which was important to me. These days, I tend to look at the movement chart as much as the O2 chart because it helps me know that I was awake at certain times when looking at my flow rate chart. Do I need it? Probabl

Oh yeah my point was really about the wellue O2 ring only. The wellue support themselves recommended me the left thumb and for me it was quite a difference. I see your point though.

I wear a Wellue O2 ring every night (except for last night when the cat distracted me right when I was about to put it on). It imports into OSCAR and SleepHQ. Most of the time, the data isn't that interesting, but I like to use the movement data to help me recognize when I turn over, or when an even

I just bit the bullet and got the Wellue O2 ring. Didn’t know how accurate alternatives were. Wellue syncs with both SleepHQ and OSCAR so you can compare the data together. If you’ve got small fingers you can probably fit into a child’s one for £50

They all have lights coming out of them because that's how pulse oximeters work. They shine two beams of light (red and infrared). It measures how much light passes through. Oxygen-rich blood absorbs infrared light, while oxygen-poor blood absorbs red light. The device calculates your blood oxygen p

If you want overnight continuous monitoring of your o2 levels then I would recommend to get the wellue o2ring-S (newest model) available on amazon.
