sleep apnea, mandibular movements, esophageal pressure, respiratory efforts, snoring.
In this paper, we propose a method for sleep apnea and hypopnea detection by analyzing the mandibular move ments recorded during sleep. This signal, highly correlated with the esophageal pressure during apnea or hypopnea, is a good marker of respiratory efforts. The respiratory ef forts and their background activity are used to detect salient mandibular movements that occur after sleep apnea and hy popnea, to delineate and to recognize episodes of sleep ap nea and hypopnea. The method presented may be extended to others breathing disorders such as Respiratory Efforts Related Arousals (RERA).
