Editors’ Note: On December 17, 2020, the New England Journal of Medicine published a research letter, “Racial Bias in Pulse Oximetry Measurement,” prompted by this essay. Read the medical study here ...

Accurate patient monitoring is not an optional extra in general practice. It is a fundamental part of the clinical encounter, ...

Every day, millions of patients have their blood oxygen levels measured with a small clip attached to a finger. Hidden within that seemingly simple technology is a 35-year-old flaw that has ...

The wearable tech landscape has changed dramatically since the first fitness trackers arrived over a decade ago. For years, the only option was a simple wristband that could track your daily steps and ...

In medicine, hypoxia is a condition in which the human body tissues are not oxygenated sufficiently to maintain adequate homeostasis, resulting from inadequate oxygen delivery to the tissues due to ...

That’s where pulse oximeters come in. These small devices measure your heart rate and SpO₂. They give you another way to understand how your body responds during exercise and recovery. Also, they may ...

Researchers developed a transparent smart contact lens that uses gold nanoparticle-embedded PEDOT:PSS nanowires to improve ...

There has never been a better selection of fitness trackers, but with choice comes confusion. We're here to help you narrow your options and find the best fitness tracker for your needs and budget. We ...

Abstract: We investigate the impact of melanin concentration on the accuracy of oxygen saturation SpO2 estimation using reflective photoplethysmography (PPG) measurements. Monte Carlo (MC) simulations ...
