    Self-Evaluation of Sleep 

    Apnea at Home

    Frequent loud snore, stops breathing, gasps or chokes during sleep, experiences excessive restlessness at night or feels excessively sleepy during the day. 

    These are probably sleep apnea symptoms.

    Quick, easy and affordable! Screen for sleep apnea with the 02 Ring. It can help track overnight blood oxygen saturation and help to self-evaluation of sleep apnea at home. 


    of sleep cases are undiagnosed

    Many people living with serious sleep conditions 

    donā€™t even know it.


    Any value of blood oxygen level below 92% should keep a look-out

    The number and duration of blood oxygen desaturations are also important. A continuous monitor that can record every change in blood oxygen levels overnight is essential. If the blood oxygen level only drops below 92% once or twice during a 7-hour sleep or lasted only a couple of seconds, it's not a reason for worry.

    Perfectly Work With CPAP

    Best Aid to Monitor the Effectiveness of Your CPAP/APAP/BiPAP Therapy

    Detailed Sleep Report During PAP Therapy

    Just wear O2Ring on your finger while sleeping, and check the record in the morning. O2ring mainly checks two important pieces of information ā€“blood oxygen saturation, and pulse rate. 

    The pulse rate generally increases and the blood oxygen saturation level generally decreases during apnea events. 

    A Safety Net Against 

    CPAP Failure

    A gentle vibration helps to keep you aware of times when your CPAP treatment may not be supporting you properly. 

    When Blood O2 levels drop below a preset level, the vibration alerts you.

    Important Gauge of Your 

    Treatment Effectiveness

    Gathering data over many nights will help you determine if your current CPAP treatment is actually working or needs an adjustment. If the oxygen saturation levels are nice and steady, the therapy is really controlling your sleep apnea. 

    Conversely, if the oxygen saturation levels are unstable and sometimes below 92%, then you might need to make some adjustments to our CPAP therapy.
