Obstructive sleep apnea is a sleep disorder in which breathing is briefly and repeatedly interrupted during sleep. The "apnea" in sleep apnea refers to a breathing pause that lasts at least ten seconds. Obstructive sleep apnea occurs when the muscles in the back of the throat fail to keep the airway open, despite efforts to breathe. Another form of sleep apnea is central sleep apnea, in which the brain fails to properly control breathing during sleep. Obstructive sleep apnea is far more common than central sleep apnea.
Obstructive sleep apnea, or simply sleep apnea, can cause fragmented sleep and low blood oxygen levels. For people with sleep apnea, the combination of disturbed sleep and oxygen starvation may lead to hypertension, heart disease and mood and memory problems. Sleep apnea also increases the risk of drowsy driving .
The National Sleep Foundation offers a number of resources to help patients who are currently suffering from or think that they may have sleep apnea. Explore the sections below for more information:
More than 18 million American adults have sleep apnea. It is very difficult at present to estimate the prevalence of childhood OSA because of widely varying monitoring techniques, but a minimum prevalence of 2 to 3% is likely, with prevalence as high as 10 to 20% in habitually snoring children. OSA occurs in all age groups
