What is Obstructive Sleep Apena (OSA)?
OSA is a Sleep Disordered Breathing ( SDB) condition which occurs during sleep, due to the narrowing or total closure of the airway.
When your airway is narrow, you or your partner may notice that you snore.
Snoring is often no greater problem than the noise itself. However, loud snoring may be a sign of a more serious problem – Obstructive Sleep Apnea.
OSA occurs when the airway becomes completely blocked and breathing stops. The brain then detects the lack of oxygen and prompts a momentary arousal to draw breath. Although OSA sufferers may experience hundreds of apnea episodes per night, they are unlikely to remember any of them. In fact, if the sufferer lives alone or sleeps separately they may not be aware of their condition, even after many years.
