Obstructive sleep apnea among other breathing disorders are caused by episodes of airway collapse that block the breathing. In CPAP therapy, a light-weight mask is placed over the nose while you sleep. The mask is attached to a small unit that provides continuous air pressure to the nasal passage. The forced air delivered by CPAP prevents the episodes of airway collapse by keeping the windpipe open, eliminating snoring and providing a better, more restful night’s sleep. It is one of the most common and effective treatments of sleep apnea and can be used to treat sleeping disorders in adults and children.
