Patients are wired up for a sleep study to determine degree of apnea. Sensors variously detect brain activity, snoring sounds,

An event happens in obstructive sleep apnea syndrome. When breathing starts again, there is typically a deep gasp, and then the resumption of snoring. A 2005 study in the British Medical Journal found that learning and practising the didgeridoo helped reduce snoring and sleep apnea, as well as daytime sleepiness.

Obstructive sleep apnea syndrome (OSAS) is a potentially disabling condition characterized by excessive daytime sleepiness. However, some evidence indicates that snoring is one end of a clinical continuum with an opposite extreme of severe obstructive sleep apnea snoring.
