Sleep Apnea
Is definted
Episodes of apnea and hypopnea associated with symptoms such as excessive daytime and cardiovascular morbidity and mortality

Pathophysiology
1.- During sleep, there is decreased tonic activity of the laryngeal, supraglottic, oropharyngeal, nasopharyngeal, and lingual musculature, which results in dynamic collapse with respiration.
2.- This decreased upper airway tonic activity results in a dynamic decrease in the caliber of the upper airway and therefore increased resistance to airflow.
3.- The effects of this dynamic collapse can range from mild collapse without significant changes to respiration and no effect on oxygenation or arousal to complete airway obstruction, decreased oxygenation, and frequent arousals throughout sleep

Incidence
In North America found prevalence rates for an AHI of more than five episodes per hour of 24 percent in men and 9 percent in women, and for OSAHS with an index greater than five episodes per hour plus excessive sleepiness of 4 percent in men and 2 percent in women.
