Obstructive sleep apnea is the most common form of sleep-disordered breathing, affecting a significant population world-wide. Descriptions of sleep-disordered breathing date back to 200 years. Obstructive sleep apnea (OSA) has been associated with an increased risk of cardiovascular disease, stroke, pulmonary and systemic hypertension, and increased risk of automobile accidents, insulin resistance and arrhythmia.
Classic suspicion of obstructive sleep apnea is usually raised by complaints of snoring or daytime fatigue despite adequate duration of sleep. Indeed many patients are asymptomatic and present with atypical presentation to their physicians with hypertension, arrhythmia, or congestive heart failure.
