O2Ring continuously monitors blood oxygen saturation (SpO2) and heart rate to help detect sleep apnea. When sleep apnea occurs (a pause or stop in breathing), blood oxygen levels drop. O2Ring detects this drop in oxygen saturation along with heart rate changes and alerts the user through vibration.
I purchased this Wellue O2 ring as replacement of previous example of same. This is now the 3rd Vellue O2 Ring. Both previous rings i needed to replace after approx 2 years of use at which time they started to return implausible/erratic readings. These are very easy and comfortable to use but with a returned usefull life of only about two years I did search around but could find no alternative with same ease and comfort of use so best I could do was find this one at slightly more reasonable
Great accompanying app, the unit does what it says, ideal for wearing while sleeping. Only con would be the ring band has a stretchy thin piece bridging the bottom of the ring band. This will likely break at some point, perhaps a Velcro strap may have been better.
