First, pause and take a deep breath. When we breathe in, our lungs fill with oxygen, which is distributed to our red blood cells for transportation throughout our bodies. Our bodies need a lot of ...

Blood oxygen levels refer to the amount of oxygen circulating in the blood. Normal blood oxygen levels fall between 75 and 100 millimeters of mercury (mm Hg) on arterial blood gas (ABG) test results.

Higher oxygen saturation targets are linked with greater progression in some cases of retinopathy of prematurity (ROP), but the incidence remains stable. Increased oxygen saturation targets in ...

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 ...

First, pause and take a deep breath. When we breathe in, our lungs fill with oxygen, which is distributed to our red blood cells for transportation throughout our bodies. Our bodies need a lot of ...

A dangerously low oxygen level—usually below 92%—can cause shortness of breath, confusion, chest pain, or fainting. It’s ...

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 ...

For the past few weeks, the Pixel Watch has been missing estimated oxygen variation (EOV) data in the Fitbit app, but the graph is now back. This metric is an “approximation of the changes in your ...

We spend much time working in buildings with sealed windows, in vehicles with closed windows and homes with closed windows. This reduces the amount of oxygen we get. Limited oxygen translates to a ...
