Obstructive sleep apnea is the intermittent interruption of airflow
through the nose and mouth that occurs during sleep and is considered present
when individuals have more than 5 apneic episodes per hour of sleep.1 Data from a cross-sectional population-based study2 suggest that sleep-disordered breathing occurs in
approximately 10% of randomly selected women and in 25% of men, many of whom
appear to be asymptomatic and unaware of their breathing abnormality during
