Hundreds of thousands of people trust Onyx, the first self-contained digital fingertip pulse oximeter. Incorporating the electronics and sensor into one unit – the easy-to-use Onyx provides a ...

Doctors typically monitor oxygen levels in the blood with a device known as a pulse oximeter. Most of us remember it if we’ve ever been in a hospital: a clamp on the end of our finger.

Pulse oximeters clamp onto a fingertip and send light beams through the finger to estimate pulse rate as well oxygen levels of the blood. A sensor on the other side of the device receives those ...

The theory behind a pulse oximeter relies on the fact that hemoglobin absorbs red and infrared light differently based on its oxygenation levels. By shining a red and IR LED through a finger onto ...

One way to measure oxygen saturation is to use pulse oximeters — those little clips you put over your fingertip (some shown here in gray and blue). In a proof-of-principle study, University of ...
