I've used it only one night so it is too early to draw major conclusions, but I woke up feeling more rested than I have in memory. I didn't wake up at 3AM like I always do. I suspect the vibrating that occurs when the 02 saturation drops below 90% woke me up just enough to have me roll onto my side (something I've been trying to do, since I don't snore when I sleep on my side), but I have no recollection of that. All I know is that the phone app shows I had several excursions below 90%, all of which I slept through, and I woke up refreshed. No morning headache, either. My apnea is quite mild, so I'm hoping this will help me manage it without further intervention of devices.

As a physician with a serious illness and respiratory failure, I require oxygen. However, I cannot tell when my oxygen sat levels drop, even to 70s. Most people have no idea when they are in the low 90s, although that is a level we recommend straight to the ER and consider pneumonia. Traditional finger monitors are not continuous and restricts all hand usage. I have three separate ones and they all correlate to the ring, except the ring is fsater. This RING changed my life. I can unhook my oxygen from my trach and not have to constantly try to find my clip type and check randomly. Also, the overnight monitors are bulky and alarms wake my husband. I had a problem with one, a new one was immediately sent. I wear mine 24/7 and can set the sat alarm to my personal numbers. I have not seen anything even close to it on the market. I would recommend it especially now, because new viruses can have a first symptom of low oxygen and you don't know it. If you are sick and it goes low, you know. If you didn't, the decision to risk an ER waiting room would end up costing WAY more than this ring. It doesn't interrupt my life, the readings are spectacularly accurate since I wear mine while in the ICU or ER and monitored as well.

I think anyone who wants to take charge of their sleep apnea treatment should have one of these. Part of my morning routine is to download the data onto my ipad and take a look at how I slept last night. This has helped me identify lifestyle factors that significantly impact my blood oxygen while sleeping. Wearing it even on the rare night when I'm too lazy to get the CPAP system together has helped show me how important the CPAP really is.

Using this regularly helped me notice how much variability in my sleep apnea there is from night to night. A single night lab sleep study might have just been an abnormal night, so this actually gives much more useful data about your ongoing sleep quality, in my opinion.

I also have used a fitbit and apple watch to monitor spO2, but they don't give anywhere near the amount of information this does. They sample data a few times per hour at most, while the oxyring samples every few seconds. This granularity of the data allows you to see momentary drops in spO2 and complex patterns that would be completely missed on the fitness watch. Fitness watches try to reduce everything to a single numerical score for the night, whereas this gives you the fine grain data, all in one screen on the ipad, to see beyond the score.

One suggestion for care: make sure to wipe skin oils off every morning because over a year or two I have found the silicone rubber to get less firm, loosening the fit over time. This issue can be partially solved by moving to a larger finger when it happens.

I have purchased a dozen of these Vibeat OxyRings, over the last couple of years. I gave one to each of various family members for Christmas. I wear mine every night to monitor my sleep APNEA which I discovered through using the ring is the type called “positional sleep APNEA”. If I sleep on my back, my O2 levels suffer. If I sleep on my side, my O2 levels are OK. I use the ring as a recording biofeedback device to prompt me to roll onto my side when low O2 levels are detected. My wife has noticed the improvement in my sleep, and the fact that I snore a lot less. My good results also show in the charts in the app which I review every morning. I do not sleep without it.
