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

摘要

The present invention discloses an apparatus and method for predicting a rate of reduction of apnea low apnea index before surgery for the treatment of obstructive sleep apnea. According to an embodiment of the present invention, the apnea low respiratory rate reduction rate prediction device is considered in consideration of visibility of tonsils based on at least one of tonsil size, area of pharynx, tonsil column and palatine uvula. A tonsil size grading unit for determining a tonsil size grade, a data collection unit for collecting the results of polysomnography, and the determined tonsil size grade and the collected results are used to calculate a reduction rate of apnea hypopnea index It may include a calculating unit.
