Introduction

Obstructive sleep apnea (OSA) is a condition of cyclical or repetitive obstructions of the upper airway during sleep, with micro-arousals occurring at the termination of a respiratory event (1,2). In adults, micro-arousal activity has been postulated to disrupt the normal restorative processes of sleep and has been demonstrated to produce sleepiness and/or daytime performance deficits when induced by various sensory stimuli in normal subjects (3,4). In addition to nonrestorative sleep, OSA has been found to have a strong association with cardiovascular disease (5), including hypertension (6), congestive heart failure (7), cardiac arrhythmias (8), coronary artery disease (9), and stroke (10).

There are several different modalities that have been found to be effective for the treatment of OSA. The first-line treatment however, has become the use of positive airway pressure (PAP) therapy, especially continuous positive airway pressure (CPAP) therapy (11). The first reported use of nasal CPAP for OSA in adults was by Sullivan et al. (12) in 1981. The therapeutic mechanism of successful treatment is the creation of a "pneumatic splint" by an effective positive pressure applied to the pharynx, providing immediate relief from obstruction (13), thus allowing sleep continuity and preservation of sleep architecture (14,15).
