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 ...

A recent report out of Oregon State University paints a picture of how ocean oxygen levels have decreased in the Pacific Northwest over the years. The report found near-bottom levels of dissolved ...

New research suggests that exposure to lower oxygen levels at high altitude may trigger biological changes that could benefit people living with diabetes.

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 ...

Scientists have long known that people living at high altitudes, where oxygen levels are low, have lower rates of diabetes than people living closer to sea level. But the mechanism of this protection ...

Janay Reece came back home to Baltimore to join WJZ in August 2023. Before coming back to the Charm City, Janay was a morning anchor and reporter for WDBJ7 in Roanoke, VA. She joined the WDBJ7 morning ...

Researchers have found evidence that low oxygen levels in tumors could actually enhance some of the body's immune responses against cancer, in contrast with the general paradigm that hypoxia ...

A recent study explored one possible cause -- hyperoxia or high concentrations of oxygen given to such patients during surgery -- as opposed to doses more similar to air. The study concluded that ...

Low oxygen and rising carbon dioxide in mangrove waters may shrink critical nursery habitat for young fish and threaten ...

This means that low blood oxygen levels may be missed in patients with darker skin tones, potentially delaying care, while patients with lighter skin tones may get unnecessary treatment. Pulse ...
