Wellue O2 Ring™ - Ring Oxygen Monitor (2024)

FAQs

Is Wellue o2 ring FDA approved? ›

After that, you can turn on your phone, open the app and allow it to sync. Blood oxygen measurements appear to be accurate when compared with a traditional oximeter. That's to be expected considering Wellue has secured FDA approval for the device.

The ring is also very accurate. I have compared it to the readings with my other two oximeters, as well as the readings I get when my oxygen saturation rate is measured at my doctor's offices.

During waking hours, healthy adults often have an SpO2 of about 95% to 99%, but this may drop by a few percentage points during sleep. When awake, SpO2 levels below 92% may be a sign of insufficient oxygen. Levels below 88% should prompt immediate medical attention.

It was founded in 2012 and is based in Cromwell, Connecticut.

When it comes to choosing the finger for pulse oximeter readings, the general consensus is that the middle finger or the index finger provides the most accurate results. These fingers are typically preferred due to their adequate blood flow and the thickness of the skin in the fingertip area.

Conducted by researchers at the University of Washington (UW) and University of California San Diego (UC San Diego), the proof-of-concept study found that an unmodified smartphone camera and flash along with an app is “capable of detecting blood oxygen saturation levels down to 70%.

The ring is elastic, inside circumference range is about 2.0~3.2 inch. Thumb and index finger are preferred. General rules: 1）Do not use middle finger.

Oxygen levels between 95% and 100% are optimal for most people.

For that reason, pulse oximeters and other sleep trackers are better suited for at-home monitoring of blood oxygen levels during sleep. Blood oxygen levels can vary slightly during sleep. For example, oxygen saturation levels may show a minor increase or decrease with changes in sleeping position.

Normal and Dangerous Oxygen Levels During Sleep

Normal blood oxygen levels vary from person to person, but for most it's around 95% to 100% regardless of whether they are asleep or awake. A blood oxygen level below 92% may be a cause for concern, while a level below 88% requires prompt medical attention.

People should contact a health care provider if their oxygen saturation readings drop below 92%, as it may be a sign of hypoxia, a condition in which not enough oxygen reaches the body's tissues. If blood oxygen saturation levels fall to 88% or lower, seek immediate medical attention, says Dr. Lutchmansingh.

Low oxygen level, also called hypoxemia, is considered a reading between 90% and 92%. A reading this low means you might need supplemental oxygen or that there may be challenges that affect how your lungs function. A result below 90% indicates that you should seek medical attention.

Shortness of breath does not always indicate that you are hypoxic. In other words, your level of dyspnea, or air hunger, does not always correlate with your oxygen saturation. This means that you can be short of breath, even extremely short of breath, even in the presence of normal oxygen saturation.

Masimo announced it received FDA clearance of MightySat Medical, making it the first and only FDA-cleared medical fingertip pulse oximeter available over-the-counter direct to consumers without a prescription.

The Belun Sleep System is FDA cleared for in-home sleep apnea tests. The Belun Ring is a cableless photoplethysmography (PPG)-based wearable that is worn on the index finger while sleeping. It records patients' oxygen saturation, pulse rate, and actigraphy for up to 10 hours per night.

At this time, the FDA has not approved or cleared any oxygen concentrators to be sold or used without a prescription. When using an oxygen concentrator: Do not use the concentrator, or any oxygen product, near an open flame or while smoking.

Also: NIH awarded Mount Sinai researchers $4 million to develop an artificial intelligence-powered model to detect adverse outcomes of obstructive sleep apnea.
