Typical steps

1) START.Charge the battery. Wear the sensor on thumb, index finger as option in case of too tight for thumb. 

2) STOP.The device turns off automatically in a moment after you take off the ring. Open app to sync data which will help you get sleep insight.(If the working time is less than 2 minute, the data will not be saved)

DATA Sync

Open App to sync data, check results.


Do I need to keep my Oxylink close to my cell phone?

No, you don’t. 

Bluetooth communication distance is required to be less than 20 meters. When the device gives an audible alarm, the mobile phone will give an audio alarm at the same time.

Why do I need to allow Location access for Android?

With android phone, you need to allow Location access to make Bluetooth work. We DO NOT collect your location data.

Do I need to power off the monitor manually?

Usually no need. If you don’t use it, it will power off automatically in a while.

It is not necessary. The built-in storage is up to 4 sessions.

Why I get different readings by Oxygen Monitors of Wellue and other manufacturers? 

Please be assured that all Wellue products provide medically accurately measurement.

Different manufacturers utilize algorithms with different average SpO2 times, which is a significant element when calculating the reading. The shorter the collecting duration, the more sensitive the result, the fast the response. Oxygen monitor with too long assessment time is not the best choice for oxygen saturation detection, especially during sleep. Wellue’s intelligent averaging algorithm collects data quickly and identifies the precise SpO2 value. 

Therefore, it is not rigorous to compare oxygen monitors that utilize different averaging algorithms.The comparing result will be much more accurate if obtained by an arterial blood gas.
