When oxygen disappears, most fish suffocate. This one ferments its own metabolism and waits months for spring beneath frozen ...

These underground rodents are the first mammals found to actively choose air with lower-than-normal oxygen levels. Their ...

To take a pulse oximetry reading, turn on the device, place it on your fingertip, sit still, and wait for a stable reading. Normal oxygen saturation levels range from 95% to 100%; levels below 92% may ...

Researchers in the U.S. have found that exposure to low oxygen levels — known as hypoxia — early in life can cause pulmonary hypertension (PH) by permanently altering lung blood vessel development.

MOUNT PLEASANT, Tenn. (WSMV) - A small fishing lake in Maury County has been closed due to oxygen levels in the water affecting the fish life. The mayor of Maury County, Sheila Butt, announced the ...

Scientists discovered that low-oxygen environments can shield brain cells and restore movement in Parkinson’s models, hinting at a new therapeutic path. The approach challenges long-held assumptions ...
