依據台灣睡眠醫學會的報告，每五人中就有一人出現睡眠障礙的問題，睡眠障礙的存在不僅僅是老年人和青年人。大多數睡眠呼吸中止發生在肥胖者身上，然而，他們並不知情。因此，開發一種在家中進行睡眠障礙檢測的簡單設備是必要的。
這項研究的目的是實現一個簡單的評估睡眠障礙的系統，即可在家中使用也無需負擔昂貴的費用，更不是復雜的系統。一些基本訊號包括鼾聲訊號，血氧飽和度和心率變異皆被記錄，而這些訊號都是從美國睡眠醫學院準則裏選出。
通過脈搏血氧儀（Nellcor Oximax N-600x）監測血氧飽和度（SpO2）和光電容積脈搏波圖（PPG）。首先，脈搏血氧儀提供兼顯示實時非標準化波形信號的記錄脈衝信號。接下來，SpO2顯示器顯示血氧飽和度，而當下的脈率也一同進行連續記錄。AT2020 USB麥克風具有自動減少噪音和USB端口的特點，易於設置和記錄低功率的高品質聲音適用於獲取鼾聲。
心率變異（HRV）源自光電容積脈搏波圖（PPG）的PP間期序列。時域分析方法將PP間隔以標準化的計算方式來得出心率變異。血氧飽和度則以缺氧狀況下將該時間，該數據及脈率即時記錄。22050 S / s的採樣頻率的鼾聲訊號將先分段出主要鼾聲區域並進行分析。

According to the Taiwan Society of Sleep Medicine reports, one out of every five people has the problem of sleep disorder in Taiwan. Sleep problems are highly prevalent not only elder and the youth. Most of sleep apnea occurred in people with obesity. However, most of the people are not aware of their disease. Therefore, to develop a simple device operated at home for sleep disorder detection is needful.
The aim for this study is to implement a simple device for assessing sleep disorder which can be used at home without expensive and complicated equipment. Some signals include snoring signal, oxygen saturation and heart rate variability are recorded. Those signals are selected from American Academy of Sleep Medicine Guidelines.
SpO2, photoplethysmography (PPG) and pulse rate were monitored by a pulse oximeter (Nellcor Oximax N-600x). First, the oximetry provided a record pulse signal displayed a real time non-normalized waveform signal. Next, SpO2 display showed the hemoglobin oxygen saturation level and continuous recording. Then, pulse rate can be obtained and monitored. AT2020 USB microphone with the features of low-self noise and USB port, is easy to set up and record high quality sound with low power apply are used to acquire the snoring sound.
Heart rate variability (HRV) is derived from PP interval time series of photoplethysmography (PPG). HRV with time-domain are computed from PP intervals under time-domain analysis method. SpO2 and pulse rate can be recorded directly when hypoxia. Snoring sound with a sample rate 22050 S/s was set and segmented signal processing is executed.
