A system for determining whether sleep disorders suffered based on classified physiology data and a method thereof are provided. By classifying a characteristic of physiology data in accordance with characteristic data, and determining whether a subject were suffered sleep disorders corresponding to classification of the characteristic, the system and the method can determine whether a subject were suffered sleep disorders quickly, and can achieve the effect of determining what the sleep disorder suffered by the subject is.一種分類生理資料以判斷是否存在睡眠障礙之系統及其方法,其透過在根據生理資料的特徵資料分類特徵資料後,依據生理資料的分類判斷受測者是否患有相對應之睡眠障礙的技術手段,可以快速判斷受測者是否患有睡眠障礙,並達成自動判斷受測者患有之睡眠障礙的技術功效。步驟301 測量受測者於睡眠時之生理資料步驟310 讀取受測者於睡眠時所測得之生理資料步驟330 依據生理資料產生特徵資料步驟350 分別依據各特徵資料分類生理資料步驟370 依據生理資料之各分類判斷受測者是否患有相對應之睡眠障礙
