Evaluation of Obstructive Sleep Apnea based on a Statistical Analysis of the Respiratory Events in Iraqi Individuals

The most prevalent form of sleep-related respiratory disorders, obstructive sleep apnea (OSA), is very common. It's marked by frequent cessations of breathing during sleep; these are caused by a collapsing of the top respiratory airway. Because of the complicated Polysomnography (PSG) test technique at sleep laboratories, OSA is largely undetected. The database for this research was constructed from 83 individuals (20 of them are control and 63 of them are OSA patients) from an all-night sleep study polysomnography device. The 63 OSA patients are divided into three groups according to the degree of severity to mild, moderate, and severe. Tukey multiple comparisons test was used to do multiple comparisons between different patients' groups and these comparisons will be in three directions. The first direction of comparison is the comparison between control (healthy) and severe OSA patients, the second direction of comparison is the comparison between mild and severe OSA patients, and the third direction of comparison is the comparison between moderate and severe OSA patients. Astatistical correlation analysis was performed for a respiratory event with the other events. The obtained findings [indicate the paramount importance of respiratory events analysis in classifying the severity of OSA patient's in to various degrees.
