APPARATUS AND METHOD FOR PREDICTING REDUCTION RATIO OF APNEA-HYPOPNEA INDEX BEFORE SURGERY TO TREAT SLEEP APNEA SYNDROME

摘要

Disclosed are a device for predicting a reduction ratio of an apnea-hypopnea index before a surgery to treat obstructive sleep apnea, and a method thereof. According to an embodiment of the present invention, the device for predicting a reduction ratio of an apnea-hypopnea index comprises: a tonsil size grade determination unit determining tonsil size grades in consideration of visibility of tonsils based on at least one of a tonsil size, a pharynx area, a tonsil column, and a palatine uvula; a data collection unit collecting a result value of polysomnography; and a calculation unit using the determined tonsil size grade and the collected result value to calculate a reduction ratio of an apnea-hypopnea index.
