Abstract Background: Obstructive sleep apnea is a sleeping disorder that has troubled a sizeable population. There is an
active area of research on obstructive sleep apnea that intends to better understand airflow behaviors and therefore
treat patients more effectively. This paper aims to investigate the airflow characteristics of the upper airway in
an obstructive sleep apnea (OSA) patient under light and heavy breathing conditions by using Turbulent Kinetic
Energy (TKE), an accurate method in expressing the flow concentration mechanisms of sleeping disorders. It is
important to visualize the concentration of flow in the upper airway in order to identify the severity… More >
