近年來睡眠障礙已經是現代社會中許多人的困擾,專業睡眠障礙治療,必需量測病患睡眠過程生理訊號後才能判斷。現今診斷睡眠障礙的系統主要區分為LevelI、Level II 與Level III 這三種等級;Level I 是屬於醫院或專業實驗室所設之睡眠治療室,藉由觀察病患睡眠時之生理訊號來判斷睡眠時的清況,包含腦電圖、眼動圖、心電圖、肌電圖、呼吸及血氧飽和度等。而Level II 系統與Level I 有相同的生理訊號量測種類,不同的是屬於居家型量測系統,但由於感測器眾多,所以受照護者在安裝感測器於身上時,要正確安裝是非常不容易的;所以Level III 睡眠量測系統則簡化了要安裝的感測器,Level III 系統所量測的生理訊號有心電圖(ECG)、呼吸(respiratory)及血氧飽和度(SpO2),雖然已經簡化了感測器的安裝,不過在量測心電圖和呼吸時,還是需要安裝複雜的感測器於身上,這樣安裝上不但還是有困難度,而且睡眠時,這些感測器還會影響到受照護者的睡眠品質;有鑑於此,本計劃要以Level III 系統為基礎,開發輕便型的睡眠診斷系統,並將診斷的結果透過網路傳送給遠端醫院做初步的睡眠判讀;此系統完成後,受照護者在量測睡眠情況時,只需在身上安置一個SpO2 感測器,透過本計劃開發的演算法,可以透過SpO2 感測器得到ECG 和SpO2 兩種生理參數,並以CCD 影像處理的方法來取代身上安裝的呼吸帶,以得到睡眠時的呼吸訊號,這樣不但能減輕睡眠時的不適感,還能簡化安裝時繁雜的過程,就能大大的增加量測睡眠時的舒適和方便性。
Sleep disorder is one of the major diseases in modern society. The way to diagnose sleep disorder needs patient's biomedical signals during sleep, and there are three levels according to the complexities of sleep recording measurement. The highest class, Level I, usually was set up in the hospital or professional lab; Level II measures the same signal patterns but at patient's home. Level II are more approaching the patients real sleep situation but without the immediate monitoring by the expert. This project is going to set up a Level III portable sleep monitoring system, and use the CCD sensor replace traditional respiratory movement. A handful sleep stage classification algorithm based on ANFIS, and transfer the categorized result to Hospital by network. The simplifying of sensor can help patient more easily to set up biomedical signals during sleep. Completion of this system will improve the sleep disorder diagnosis efficiently.
