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.

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 ...

Earth's atmosphere maintains a constant level of oxygen, whether it is a wintry, rainy day or hot summer. Across the ocean, oxygen concentrations vary enormously between different places and over time ...

Monitoring your blood oxygen levels may not seem as exciting as step counting or be as obvious in its benefits as something like sleep tracking, but it's still a useful option for managing your health ...

Patients continuously monitored after surgery experienced significantly less time with dangerously low oxygen levels compared ...

Scientists rethink why giant insects once ruled the skies, finding oxygen may not explain their size or disappearance.

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 ...

Breathing is a crucial biological function essential for survival and various bodily processes. It occurs involuntarily, without conscious effort or thought. Research shows that a healthy person takes ...

Oxygen on exoplanets can be the result of simple chemical processes rather than biological ones.
