Obstructive sleep apnea
Obstructive sleep apnea (OSA) syndrome is characterized by repeated upper airway obstructions leading to sleep fragmentation and oxygen desaturations in severe cases. Narrowing and closure of the upper airway, specifically the oropharynx, during sleep is the basis of the disease. Consequences of OSA include excessive daytime sleepiness and a higher risk of cerebrovascular or cardiovascular disease (stroke, hypertension, myocardial infarct, atrial fibrillation, and vascular dementia).
