Engineers at the University of California, Berkeley, have created a tiny wireless implant that can provide real-time measurements of tissue oxygen levels deep underneath the skin. The device, which is ...

Apple will deliver a software update for recent US Apple Watch models to reimplement the ability to measure blood oxygen levels, a process known as pulse oximetry.… Pulse oximetry can be helpful when ...

Your phone camera might have another useful feature beyond taking selfies. Engineers at UC San Diego and the University of Washington published a proof-of-concept study that showed a smartphone was ...

Apple has your health in mind when it comes to the Apple Watch, which is why it added a blood oxygen sensor starting with the Series 6. This technology can tell if you’re getting enough oxygen to your ...

Pulse oximeters use light to measure how much oxygen is in a person’s blood. For most people, a normal pulse oximeter reading is between 95% and 100%, researchers said in background notes. Readings ...

As an emergency medicine physician, Dr. Owais Durrani sees this issue regularly first-hand: When he clamps a pulse oximeter onto a patient’s fingertip to measure their blood oxygen levels, the small ...

Oura, the company behind the Oura Ring lineup of wearable devices, today announced that blood oxygen sensing is rolling out to the third-generation Oura Ring. It’s a long time coming — Oura previewed ...

Smartwatches can measure everything from heart rate to sleep quality, but one health metric has become particularly relevant over the past two years: blood oxygen saturation. Two of the world's ...

Fingertip monitors known as pulse oximeters that can be used at home to detect low blood oxygen levels (hypoxaemia) give higher readings for patients with darker than lighter skin tones, finds the ...

In a proof-of-principle study, researchers have shown that smartphones are capable of detecting blood oxygen saturation levels down to 70%. This is the lowest value that pulse oximeters should be able ...
