What is Sleep Apnea?

Obstructive sleep apnea (OSA) is a condition in which breathing repeatedly stops and starts during sleep. Each pause in breathing is called apnea – literally meaning “no breath” – and can last several seconds to a minute. When breathing is irregular, carbon dioxide builds up in the bloodstream, triggering the brain to wake the sleeping person and resume breathing.

Over 20 million Americans suffer from sleep apnea, and it’s estimated that over 80 percent of moderate and severe cases are undiagnosed.

NREM Stage 3

  • Muscles relax
  • Blood pressure and breathing rate drop
  • Deepest sleep occurs

REM Sleep

  • Brain becomes more active
  • Body becomes relaxed and immobilized
