Transfer Entropy Modeling of Newborn Cardiorespiratory Regulation.

abstract：Introduction:Obstructive sleep apnea (OSA) has been associated with non-dipping blood pressure (BP). The precise mechanism is still under investigation, but repetitive oxygen desaturation and arousal induced sleep fragmentation are considered the main contributors. Methods:We analyzed beat-to-beat measurements of hemo...
