I have noticed that even when MyAir says I had excellent results, I still had significant desaturations intermittently throughout the night. The vibration did not always fully waken me. I guess that most of the time I felt the vibration without awakening and reflexively responded by changing body position or mouth/jaw situation. That always resolved the desaturation within a few seconds. Since using the ring I have never had a desaturation lasting more than 15 seconds (the ring gives this info in its app). Typically, the ring shows that I have 4-5 desats below 90% most nights. But they don’t last more than a few seconds. This despite an AHI < 5.
My latest score says that I slept 7h41m. I had 12 desats of more than 4% from my average of 97% in that time, averaging 1.6 desats per hour. I only had 1 desat less than 90% and that was 89%. That desat lasted only 4 seconds. My average heart rate was 64 bpm with the highest being 90 bpm and the lowest being 55 bpm. The app also calculates and O2 score on a scale of 1-10. This night my score was 9.6.
Some of the reviews have said that this ring is not as accurate as a real pulse oximeter. To that I say that it is accurate enough to detect desaturations and measure their length. Others have complained about breakdown of the unit. I have only had it about two weeks, but no problems with charging or other breakdowns so far. Battery life seems to cover two nights without problem. Then I recharge it.
This is a smallish ring. I am a big guy, but it fits nicely on my pinky finger. It would be too tight on my other fingers. But I barely notice it when I am sleeping. Lookee also sells the “Wellue” ring which does the same things but which looks larger in the pictures.
I think this ring gives a new dimension to sleep apnea treatment. Everyone on CPAP should have a pulse oximeter and the vibration alarm is essential with it. l Before that I sometimes awoke gagging on my own tongue, not knowing how long I was not breathing even with CPAP operating properly. Even people who are not on CPAP but are heavy snorers should consider getting one of these things. The readout might convince them to get a proper medical sleep evaluation. It could save their life and maybe let their partner have a more restful slumber.
