Abstract

The obstructive syndrome of sleep apnea/hypopnea is characterized by repeated partial or total obstructions of the upper airways (UA) [1] resulting in intermittent asphyxia and repeated micro-arousals. Sleep disordered breathing affects about 9% of males and 4.5% of females between the ages of 30 and 60 years [2], 15% to 20% of elderly people [3] and 5% to 10% of children [4]. Sleep apnea and hypopnea events are easily identified while more subtle events, such as inspiratory flow limitation episodes, are difficult to detect. Flow limitation is the result of a partial occlusion of the upper airway during sleep.
