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.
