What is “sleep-disordered breathing” (SBD)?
SDB is a group of conditions characterized by frequent and repeated interruptions to breathing. SDB includes obstructive sleep apnea (OSA), snoring, gasping for breath, hypopnea (not enough ventilation), upper airway resistance syndrome (UARS), and Cheyne-Stokes breathing.  These conditions cause oxygen levels in the body to drop significantly while at the same time, carbon dioxide concentration increases. 

Why do I snore?
You snore when something blocks the flow of air through your mouth and nose. The sound is caused by tissues at the top of your airway that strike each other and vibrate. (MedlinePlus) (Cont'd next page)
