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 ...

In previous experiments, the researchers had seen that mice breathing low-oxygen air had dramatically lower blood glucose levels than normal. That meant the animals were quickly using up glucose after ...

Oxygen is critical to life. When levels of oxygen change, it can have immediate and lasting impacts on a person's health.

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 ...

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 ...

At altitudes over 2,400 metres, lack of oxygen — a condition called hypoxia — can cause acute mountain sickness. Incidence ...

You could call it “Dead Zone East,” a 1,634-square-mile area of Gulf of Mexico bottom waters with dangerously low levels of oxygen on the east side of the Mississippi River. It's a bit larger than the ...

Giving very premature babies high concentrations of oxygen soon after birth may reduce the risk of death by 50 percent, compared to lower levels of oxygen says new research led by University of Sydney ...
