Qui savait que FEMME avait cette signification cachée 🤣!! Kylian Mbappé, mauvaise nouvelle confirmée avant France-Espagne ! Claire Chazal bientôt à la retraite : sa réponse sans langue de bois Alerte ...

Smartwatches have made heart rate and blood oxygen saturation (SpO₂) tracking part of everyday life. And to be fair, they are useful for most people who want to monitor their activity. However, if you ...

June 8, 2026 /3BL/ – Medtronic, a global leader in healthcare technology, announced FDA 510(k) clearance of its Nellcor™ pulse oximetry system with Nell-EQ™ intelligent processor. The Nell-EQ™ ...

Pulse oximeter devices routinely overestimate blood oxygen levels in darker-skinned patients—a racial bias that can trigger downstream health harms for Black individuals, compounding well beyond any ...

Following the March 2026 update for Google Pixel Watch devices, a number of users are reporting that their SpO2 (blood oxygen) and skin temperature readings have vanished from the Fitbit app. The ...

Pulse oximeters use light to measure the amount of oxygen in the blood (SpO2). For most people, a normal pulse oximeter reading is between 95% and 100%, with readings below 90-92% generally considered ...

In the EXAKT study from the U.K., the home-use pulse oximeters assessed all gave higher oxygen saturation (SpO2) readings for patients with darker skin tones than for patients with lighter skin tones.

A project led by the University of North Carolina at Chapel Hill (UNC) has studied the effects of skin pigmentation on measurements of blood oxygenation. The extent to which different skin types ...

Research confirms that skin pigmentation can reduce the accuracy of pulse oximeters. Researchers found that red light, a key component in pulse oximetry, is more strongly attenuated in pigmented skin.

Blood oxygen measurements taken with pulse oximeters in hospitals tend to be lower than they really are, according to the Equiox study, which was designed to assess the technology’s measurement ...
