Remind You to Breathe Well
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 onto your side (the recommended position) can help open your airway to breathe more oxygen.
Effective at reducing the risk of low and unhealthy blood oxygen levels during sleep, this device serves as a safety net for CPAP failure. It also helps you assess the effectiveness of your CPAP machine or oxygen concentrator while providing additional insights.
Adjustable Vibration
Customize your notifications on the app: adjust the vibration intensity and threshold to make yourself comfortable. You can also turn on/off vibration.
