A dangerously low oxygen level—usually below 92%—can cause shortness of breath, confusion, chest pain, or fainting. It’s often triggered by lung or heart conditions like COPD, asthma, or heart ...

These underground rodents are the first mammals found to actively choose air with lower-than-normal oxygen levels. Their remarkable ability to survive these conditions could offer a key model for rese ...

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 ...

Marine life receives its oxygen from warm water on the ocean's surface, but if there's no mixing with the colder water sitting below, then bottom-dwelling marine life, like lobsters, are unable to ...

Long Island Sound experienced this year the lowest levels of hypoxia, or low oxygen, since monitoring of water quality began nearly four decades ago, the Long Island Sound Partnership announced.

Danielle “Nellie” Bruns, an associate professor in the University of Wyoming’s Department of Zoology and Physiology, has received a five-year, $1.78 million research grant from the National Institutes ...

Rivers, streams, lakes, and reservoirs aren't just scenic parts of our landscape -- they're also vital engines for life on Earth. These inland waters 'breathe' oxygen, just like we do. But a new study ...

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

Researchers from the Broad Institute and Mass General Brigham have shown that a low-oxygen environment—similar to the thin air found at Mount Everest base camp—can protect the brain and restore ...
