Sleep apnea is classified as a dyssomnia, meaning abnormal behavior or psychological events occur during sleep.When breathing is paused, carbon dioxide builds up in the bloodstream. Chemoreceptors in the blood stream note the high carbon dioxide levels. The brain is signaled to wake the person sleeping and breathe in air. Breathing normally will restore oxygen levels and the person will fall asleep again.
People have issues with excessive daytime sleepiness (EDS) and impaired alertness. In other words, common effects of sleep apnea include daytime fatigue, a slower reaction time, and vision problems.SA may increase risk for driving accidents and work-related accidents. If SA is not treated, one has an increased risk of other health problems such as diabetes.
The National Health and Nutrition Examination Survey (NHANES) introduced the Sleep Disorders Questionnaire in 2005 for participants 16 years of age and older. This analysis was conducted using data from the last two survey cycles (2005?2006 and 2007?2008) to include 10,896 respondents aged ?20 years.
