Apport de l'analyse spectrale à l'analyse du sommeil

Normal sleep is characterized by the presence of all sleep stages with a cyclic organization and the absence of sleep fragmentation. These parameters are easily recognized on a colour density spectral array. Spectral colour array is now available on various sleep recorders. These data permit a more reliable analysis of sleep than automatic sleep staging, if this latter is not carefully validated by a neurophysiologist. A sleep score based on colour density spectral array allows sleep quality evaluation and help practitioner in the evaluation and the follow-up of patient as well in sleep disturbance as in patient with sleep apnea.
