SIMULATION OF FLOW AND STRUCTURAL DYNAMICS IN HUMAN UPPER AIRWAYS

摘要

Obstructive Sleep Apnea and Hypo Apnea Syndrome (OSAHS) is a respiratory disorder characterized by repeated episodes of partial or complete airway obstruction. OSAHS is also associated with decreased quality of life, decreased cardiovascular health, day-time sleepiness, and increased transportation accidents. Its high prevalence with as much as 4 % of American population suffering from OSAHS also makes it an important health care issue[l]. Existing surgical treatments suffer from a moderate to high successful failure rates. Broader research on this respiratory disorder for a better understanding of the pathophysiology of human upper airway, to develop better diagnostic methods and treatment modalities is very much needed.
