Obstructed Sleep Apnea (OSA) afflicts 20 million adult men and women in the United States. People who have OSA stop breathing repeatedly during sleep because the airway collapses.
Airway collapse may be due to such factors as a large tongue, extra tissue in the airway, or decreased muscle tone holding the airway open.
As a result, air is prevented from getting into the lungs. These pauses in breathing can happen 30 times or more per hour. When healthy sleep is interrupted in this way, the risk of developing cardiovascular disease and other serious health conditions may increase.
