Sleep apnea afflicts millions of adults. The word ‘apnea’ comes from the Greek apnoia a – “no” or “not”, and pneo/pnein – “air” or “breathing”. It literally means ‘no air’ or ‘not breathing’. The term is used to describe a medical condition wherein the afflicted person stops breathing for a brief period of time. Sleep apnea is simply the specific condition of apnea that occurs while sleeping.
There are two forms of sleep apnea – obstructive sleep apnea (OSA) and central sleep apnea (CSA). Of the two, OSA is much more common. It was once believed to be a rare occurrence, but the ability to test for it has uncovered the truth. Approximately 18 million adults in the United States are currently suffering from OSA today.
