Snore; Apnea - ResMed AirSense 11 Manual

Snore

Snoring is sound generated by vibrations of the walls of the upper airway. It is often preceded by flow
limitation or a partial obstruction of the airway.

Apnea

The enhanced AutoSet algorithm detects both obstructive and central apneas. If an apnea occurs, the
device responds appropriately.
Obstructive apnea
An obstructive apnea is when the upper airway becomes severely limited or completely obstructed.
AutoSet generally prevents obstructive apneas from occurring by responding to flow limitation and snoring.
If an obstructive apnea occurs, the device will respond by increasing pressure.
Central apnea
During a central apnea, the airway will remain open, but there is no flow. When a central apnea is
detected, the device responds appropriately by not increasing pressure.
