I have bought two O2Ring and one is used every night. I also use a CPAP. Since I some times take my mask off during sleep, the O2Ring will wake me up when I stop breathing. The second Ring is a spare.

02 Ring Oxygen Monitor

I love these rings. I purchase two so I could monitor my oxygen 24/7. The best thing is the peace of mind I get from always knowing what my oxygen level is. I know when it's time to sit down and let my oxygen catch up and the Ring wakes me up at night if my oxygen falls too much so I can get up and get my heart pumping. This has given me the freedom to move again instead of being worried about my oxygen level all the time

Ring oxygen monitor

Love it so easy to use and wear

Useful information

liked the continuous monitoring of SPO2 which provide more information than single reading and results suggested possible sleep apnea which needs further investigation. Instructions on how to use are a little confusing and lacking.

GREAT for persons with Oral Sleep Appliances

I was looking for some easy way to get oxygen data reports for patients using a Mandibular Advancing Device. Patients can use this to confirm settings before going for another Home sleep or overnight lab testing for Sleep Apnea. This ring is easy to use , and with the app it automatically downloads its data into the app. The data summary is easy for a professional and patient to understand and easy for the patient to print out or to export. I do have a fear of it being easily lost- it is small, - it needs to have a tracker on it or at least be a neon color!

Works great

I’m very happy with my O2ring. It’s especially useful while I sleep. My Apple Watch tracks O2%, but the readings are at intervals. With O2ring, I see the whole timeline, and can see when I drop dangerously low. It’s a great tool to help me and my doctor.

Lung and Heart Problems

It’s great ring as it gives you peace of mind when sleeping and let’s you know every time when heart or oxygen have dropped and on one occasion my oxygen had come off and I just put back on otherwise when it drops to far you can get not drunk state where you might not pic up phone for help, so ver good item to have if you have bad lungs or heart, one night it kept going off and it wasn’t my lungs it was my heart which decided to sit on around 40 to 45 beats a minute, and all of this gets relayed to phone so you can send to doc to check and go from there, brilliant.

Rings are a bit expensive. However they are the best (maybe only) continuous monitoring puls/ox I have been able to find. This is my second pair. The alarm function has woken me when I lost my O2 supply. So perhaps even saved my life.

Simple Evaluation of Sleeping Oxygenation

I’m hesitant to load apps on my cellphone, but the ViHealth app connects well by bluetooth to the Wellue oximeter ring. The nightly comparisons of SpO2/HR/Movement generate good profiles of levels of problems if any. For instance, low O2 scores were noted in my recent subtle Covid onset.

Excelente monitor de Oxigênio para o dia a dia

Este monitor de Oxigênio e Pulso cardíaco é maravilhoso, porque seu uso noturno não atrapalha em nada o sono, seu uso é imperceptível pois é igual a se usar um anel e os relatórios que se tem são maravilhosos. Os dados de segundo a segundo são precisamente medidos. E ainda pode-se programar para que o aparelho vibre e acorde a pessoa caso algo esteja mal, evitando-se falta de oxigênio no cérebro enquanto está dormindo. Recomendo muito.
