Obstructive Sleep Apnea (OSA) is a syndrome characterized by episodes of airway obstruction, which causes oxygen desaturation events. These events can be identied by oximetry analysis and are used as one of the parameters to diagnose OSA. However, desaturation events have an inaccurate denition in manuals and in most of the literature. Thus, this work aims to evaluate whether different methodologies for the calculation of desaturation events impact the Oxygen Desaturation Index (ODI) and the diagnosis of OSA. The results indicated that the ODI values are signicantly different from each other (p <0.001) and the methodologies provided variable performance for the diagnosis of OSA.
