What's Wellue O2Ring?

The Wellue O2Ring is a smart ring oxygen monitor that continuously tracks a user’s blood oxygen saturation, heart rate, and body movement every second the ring is worn.  The device is FDA-registered and used by clinics across the United States.

Who Can Use Wellue O2Ring?

The Wellue O2ring is best used by people with snoring problems, sleep apnea, chronic obstructive pulmonary disease (COPD), pneumonia, and asthma. Pilots — or anybody who wants to keep tabs on their oxygen levels every second — can also take advantage of this smart ring.

Vibrating Alarm

The Wellue O2Ring has a built-in vibrator that alerts the user when the blood oxygen drops below normal levels or irregular heart rate occurs. The vibrating alarm can be turned silent or adjusted to lower its intensity. Users can also customize the vibration intensity separately for the oxygen level and heart rate.

Health Report

Through its app for Android, iOS, Windows, and macOS, the Wellue O2Ring can deliver detailed analysis and record of the user’s overnight blood oxygen levels, heart rates, and body movements. The report shows the duration when the user’s oxygen levels go below 90% and the number of times when it drops over 4%. Users can export their data in CSV and PNG formats, so they can share it with their medical practitioners for further analysis.
