• 中文摘要

複雜的生理訊號可能會傳達獨一無二的動態特徵,使用統計學上的排序去研究分析不同種類的生理訊號。把這個方法應用 到由生理控制系統所輸出的腦電圖信號上。本研究中將此方法用於建構人體腦電圖信號模型,分析模擬在開刀期間病人經 過麻醉後,隨時間變化的動態特徵。研究中發現在麻醉剛開始時,病人的統計排序所計算出來的數值會慢慢增加到一定的 範圍後,麻醉期間則會不太會有變化,而當麻醉藥效慢慢消失後,數值又會開始慢慢減少。從這方面可以看出腦電圖動態 受到麻醉深淺所受到的影響。

• 英文摘要

Complex physiologic signals may carry unique dynamical signatures that are related to their underlying mechanisms. We used the method based rank order statistics to investigate the profile of different types of physiologic dynamics. We applied this method to brain waves fluctuations which were the output of a central physiologic control system. In this research, we build the human electroencephalogram (EEG) model by this method. To analyze the dynamical signal during the narcosis of the operation in the domain. We found that distributions of rank maps of the patients become wider at the beginning of narcosis. At deeper narcosis, the distributions of rank maps of the patients will keep wider. When the patient becomes conscious, patient will have narrow

distributions of rank maps. We can find the dynamic variation of electroencephalogram by this method.
