“Of course the ring does not diagnose conditions, but it’s important to be able to detect sleep abnormalities that could be sent to a doctor,” Dr. Kryger said, adding that the ring detected drops in saturation. “One patient I had needed oxygen at night because he was waking up short of breath,” Dr. In a test that lowered blood oxygen levels in 19 patients and measured the number of times the blood oxygen dropped beneath 90% in the circul+ ring versus a sleep lab machine, the circul+ ring seemed to be as accurate as the sleep lab machine.įor patients with lingering symptoms due to long COVID, the ring can detect drops in blood oxygen levels during sleep. And, according to third party testing, the circul+ is accurate. “The ring can be used to follow the blood oxygen levels in these patients to see if they are adequately treated,” Dr.
Kryger says the circul+ ring has been particularly helpful in measuring how blood oxygen changes during sleep in patients with Long COVID, cardiovascular disease, and sleep breathing problems. “Although wearables like the circul+ ring do not provide diagnoses, they can support telehealth because their recorded metrics can be sent directly to doctors.”ĭr. “Following the COVID-19 pandemic, medicine has changed in the sense that telehealth allows individuals to consult with doctors remotely,” Friedman says. The data is sent to a smartphone, transmitted to a secure server, and can be shared with a family member, caregiver or your doctor.

The Prevention circul+ ring can accurately measure a range of metrics that are integral to health, including continuous blood oxygen (Sp02), heart rate, finger temperature and sleep stages, but also is expertly designed to collect HRV (heart rate variability), blood pressure and a single lead ECG (a measurement of the heart’s electrical activity), with free firmware upgrades by end of year. “You can think of this ring as a little computer-It sends out continuous impulses of light and is able to measure blood oxygen level continuously,” Dr. It’s made of stainless steel and durable plastics and comes in three different sizes to fit any of your fingers. The Prevention circul+ has a unique patented design, according to Neil Friedman, COO of Bodimetrics, which allows the sensor to be stabilized against the bottom of the finger for accurate measurement. That’s because many wearables use sensors that are unstable.
“The typical at-home oximeter is not able to continuously measure and record oxygen,” says Meir Kryger, M.D., professor at Yale University and member of the Bodimetrics Advisory Board. Most oximeters that you see in labs or hospitals are able to measure blood oxygen levels or heart rate continuously however, the at-home wearable devices currently on the market can only provide a snapshot of these health metrics-until now. It does this by passing small beams of light through the finger and observing changes of light absorption in oxygenated or deoxygenated blood.
