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 through the day, every second the ring is worn. The device is also used by clinics in 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 take advantage of this easy-to-use smart ring.

You can connect O2Ring to most smartphones via Bluetooth. The O2Ring starts to operate automatically when you mount it on your finger. Its soft silicon ring fits on any finger and the battery lasts for up to 16 hours after fully charged.

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 PDF formats, so they can share it easily with their medical practitioners for further analysis.
