The  pathophysiological mechanisms underlying the  morbidity of OSAS are not completely understood,  which make the research on the OSAS an important  issue. Obstructive sleep apnea episodes were  carefully selected and segmented in three parts, the  OSA event and a certain period immediately  preceding and following the event, in order to  assess the dynamic electroencephalographic (EEG)  power changes, in four frequency bands: delta,  theta, alpha and beta. Autonomic Nervous System  activity was also assessed through the spectral  analysis of heart rate variability components in the  three mentioned periods. Continuous wavelet  transform was the elected spectral analysis  technique. To better visualize the EEG spectral  changes during OSA episodes across the whole brain,  topographic EEG brain mapping was carried out. This  research should be especially useful to health  professionals, who are focused on sleep disorders,  or to engineers interested in the analysis of  biomedical signals.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783843383301\"\u003e\u003ch3\u003eSpectral Analysis of Physiological Parameters\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783843383301","offer_id":39470126661725,"sku":"9783843383301","price":59.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/65b9bed2-4c59-4692-a173-17f43d468b9d.jpg?v=1769235177","url":"https:\/\/shop.autorenwelt.de\/products\/assessment-of-obstructive-sleep-apnea-syndrome-von-ana-coito","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
