Abstract:Oxygen saturation obtained from nocturnal pulse oximetry is a significant evaluation parameter for sleep related breathing disorders, especially in the diagnosis of the obstructive sleep apnea syndrome (OSA). Today clinical interpretation relies mainly on the number of desaturation events per hour (oxygen desaturation index, ODI). In this study various alternatives were established and their applicability for OSA screening was evaluated. The discussed methods include time-based approaches (Δ-index), non-linear… Show more
