Obstructive Sleep Apnea News and Research

RSS

Obstructive sleep apnea (OSA) is a major heath problem. In the United States, at least 17 million people have moderate to severe OSA, which is characterized by heavy snoring, airway blockage and frequent awakenings during sleep.

Scientists discover how excess oxygen changes a handful of proteins in the cells

When it comes to oxygen, you can have too much of a good thing. Breathing air that contains higher levels of oxygen than the usual 21 percent found in Earth's atmosphere can cause organ damage, seizures, and even death in people and animals, particularly if it's in excess of the body's oxygen needs.
