依據2020年AHA (American Heart Association)的指導方針：「在CPR期間使用視聽回饋裝置，以便即時發揮最好的CPR效果是合理的作法。」，本研究旨在回顧救護技術員現行使用之視聽回饋裝置的現狀，並專門針對救護技術員開發新設計。
對現行市面上常使用之視聽回饋裝置的優劣分析，參考其他功能類型視聽回饋裝置，設計開發了一款改良式視聽回饋裝置模型，以模組方式輔助救護技術員。在使用該模型進行救護技術員主觀操作測試感受，使用SPSS軟體18版作為統計工具，將結果以描述性統計與成對樣本T檢定之方式呈現。
將改良式視聽回饋裝置與另外三款以成對樣本T檢定與描述性統計後之結果，得到改良式視聽回饋裝置顯著優於他款。且多數人員表示有意願使用改良式視聽回饋裝置於執行CPR期間。
According to 2020 AHA guideline:「Use of real-time audiovisual feedback is suggested as a means to maintain CPR quality」, this study aims to review current state of audiovisual feedback equipments using among emergency medical technicians (EMTs) and develop a new design expressly for EMTs.
After analyzing pros and cons of existing audiovisual feedback equipments, we created a modified audiovisual feedback model. Survey questionnaries were given to EMTs after useing the model to evaluate their experience. Data were analyzed with descriptive statistics and paired sample t-test by SPSS 18.
The experience of using modified audiovisual feedback model was significantly better than three other equipments, and most of the participants were willing to use it while performing CPR.
