Better Way to Track Your Overnight Oxygen Levels
Wellue® SleepU™ is compact and lipstick-sized, simply wear it on your wrist for a full night, it records your blood oxygen saturation, heart rate and body movements every second continuously.
Built-in Adjustable Silent Vibration Prompt
The vibration in the patented ring sensor will nudge you gently to change your sleep position when your blood oxygen level is below the preset value.
Rolling over onto your side(recommended position) can help you open the airway to breathe more oxygen. Effective at reducing the risk of sleeping at low and unhealthy blood oxygen levels. It acts as a safety net for CPAP failure and is also optimal when not using CPAP devices.
The silent vibration instead of audible beeping doesn't disturb your partner. You can adjust intensity and threshold on the app to fit you best.
