Topic: Study of Airflow Phenomena and their effect on the respiratory system
Obstructive sleep apnea (OSA) is a common disease and is considered a serious problem. Lack of proper treatment causes severe damage to oral health. Heart attack, diabetes, blood pressure and daytime sleepiness are common symptoms. OSA is defined by an apnea-hypopnea index (AHI), which indicates its level of severity. Rapid eye movement sleep (REMS) and polysomnography devices are the most common techniques implemented to define the level of obstruction of the upper airway. Treatment suggestions are based on the AHI measurement. However, uncertainty in the measurements can lead to the wrong treatment recommendation. Computational fluid dynamics (CFD) is now implemented as a novel solution to predict the level of obstruction in the upper airway with a high level of accuracy. This project considers applying a combination of the CFD and FEA (finite element analysis) to obtain information that can predict the exact level of obstruction in the human upper airway, which can then assist clinicians to suggest superior treatment solutions.
