Product details

Description, specs & care

This is the new O2Ring-S, the upgraded version of the Wellue O2Ring. It replaces the original O2Ring. Every unit we ship is the S version.

The O2Ring-S is a soft ring oximeter that you wear on your finger while you sleep. It records your blood oxygen level (SpO2), pulse rate and movement all night. In the morning, the ViHealth app shows a full report on your phone.

What is new in the O2Ring-S

Original O2Ring New O2Ring-S
Tracking time per charge 12–16 hours Up to 24 hours
Data recorded every 4 seconds 1 second
Charging port Micro USB USB-C
  • More detail in your report. One reading every second shows short dips in oxygen that a 4-second record can miss.
  • A full night and more on one charge. You can record a long sleep without a recharge.
  • USB-C charging. Use the same cable as most new phones.

Why CPAP users wear it

  • See your overnight oxygen level and pulse rate on the nights you use CPAP, and on the nights you do not.
  • Share the report (PDF) with your doctor or sleep clinic.
  • Set a silent vibration alert for a low oxygen level or a high or low pulse rate. The vibration does not wake your partner.
  • No wires, no wrist unit and no finger clip. The soft silicone ring stays on all night.

How it works

  1. Charge the ring with the USB-C cable.
  2. Put it on your thumb or index finger before bed. It starts to record automatically.
  3. In the morning, open the free ViHealth app (iOS and Android). The ring sends the data over Bluetooth.

The ring stores up to 4 sessions of up to 10 hours each, so you can sync later if your phone is not near.

Important

The O2Ring-S is a monitor. It does not diagnose sleep apnoea or any other condition. Talk to your doctor about your results and before you make changes to your therapy.
