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.

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 ...

Reducing oxygen levels in critically ill children on mechanical ventilators in intensive care could save tens of young lives each year, finds a new study. Reducing oxygen levels in critically ill ...

Oxygen levels in the Earth's atmosphere are likely to have 'fluctuated wildly' one billion years ago, creating conditions that could have accelerated?the development of early animal life, according to ...

Reducing oxygen levels in critically ill children on mechanical ventilators in intensive care could save tens of young lives each year, finds a new study led by researchers at UCL and Great Ormond ...

Fingertip monitors known as pulse oximeters that can be used at home to detect low blood oxygen levels (hypoxemia) give ...

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 ...

A new study led by former Syracuse University doctoral student Ruliang He and co-authored by his advisor, Earth and environmental sciences Professor Zunli Lu, reveals that Earth's ancient tropical ...

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 ...
