Braun Pulse Oximeter 1 (Oxygen Saturation, Blood Oxygen Levels, Clinically Accurate, Certified Medical Device) YK-81CEU

Product Information

Every wearable we've tested that has a pulse oximeter function clearly states that the data should not be used for medical purposes. In a clinical setting, pulse ox probes tend to differ, according to board-certified internal medicine specialist Spencer Kroll, MD, PhD. A key symptom of respiratory illness is diminished lung function, which may lead to lower blood oxygen levels. The Braun Pulse oximeter 1 measures blood oxygen levels. While both devices can help you monitor your health at home, neither can confirm a COVID-19 diagnosis. The only way to know for sure if you have a current COVID-19 infection is to have a swab test. For The Whole Family– It can be used for adults and as a pediatric pulse oximeter for children 12 and older.

Pulse oximeter probes or sensors can be attached to your fingers, nose, ear, toes, and forehead, explains board-certified internist Jaydeep Tripathy, MBA-MPH, PhD. It can be used to monitor how fast your heart is beating by measuring your pulse rate, which is calculated in beats per minute or bpm. It can also be used to assess how well your body is breathing by measuring oxygen saturation in your blood, which is displayed in percentages. Some pricier devices go a step further and include measurements such as body temperature,perfusion index, and plethysmograph.

You must rub your ear lobe vigorously for at least 5 seconds before attaching the clip and ensure it’s correctly positioned to cover the light sensors. If you don’t position it properly, you may get an inaccurate reading. Here's a selection of tested models to give you an idea of what features you get at different price points:

According to Dr. Medbery, a normal level of oxygen saturation (SpO2) in your blood is usually 95 percent or more, though “some people with chronic lung disease or sleep apnea can have normal levels around 90 percent.”

If you’ve ever been hospitalized for respiratory distress (or, in many cases, for anything from birthing a baby to undergoing surgery), you may have been hooked up to a medical-grade oximeter that provided an ongoing picture of your oxygen saturation.
