本論文介紹一個電腦化肺音擷取系統，這個系統可以記錄肺音、呼吸氣體流向、聽診位置及進行異常肺音的偵測並可以重覆播放已記錄之肺音。這個系統的介面是以Labview程式來撰寫，透過信號調節電路來記錄肺音、資料擷取電路將資料數位化後儲存至個人電腦;使用熱敏電阻來偵測呼吸氣體流向，進而去偵測呼吸狀態為呼氣、吸氣、或暫停這三種呼吸狀態。異常肺音爆裂音的偵測是利用其波形爆炸性的特徵來偵測;哮鳴音的偵測是利用其波形近似於弦波的特性來偵測。這個系統可用以收集肺音以及建立肺音資料庫，也可作長時間肺音監測之用。
傳統聽診法由醫師聽診完畢後，因無法記錄肺音、呼吸氣體流向、聽診位置等相關疾病資訊，相對地也就不能重覆利用這些資訊，因此電腦化肺音肺音擷取系統可改善傳統聽診法的缺點。此系統未來可開發成電腦化肺音聽診系統，所以建立一個電腦化肺音擷取系統是有助於肺音的研究。
