This price is to purchase this item. This is an FDA-registered high-resolution pulse oximeter with pulse rate, temperature, blood pressure, heart rate variability, ECG lead, and hypnogram. This is not a home sleep study. It is useful for monitoring your progress with oral sleep appliances, EPAP therapies, and other sleep apnea treatments. It can be used for titration monitoring and adjusting and can be a way to determine if you need a sleep study. The data is stored and displayed on an app on your smartphone or in a cloud storage. It can also monitor oxygen levels while exercising and daytime averages.

This Ring is one of only a few clinically tested to be non-racially biased and will produce remarkable accuracy even compared to quality polysomnograms on all skin pigmentation types. The Circul+ ring is warranted for 1 (one) year from purchase, including battery life.

This ring far outperforms popular rings of similar intent on the market and is accepted by pulmonologists as accurate and trustworthy. Other rings are not accepted by pulmonologists.
