App for Basic Life Support based on Android Smartphone

This study is to develop a basic life support (BLS) app using the android based smartphone and to evaluatethe function of the app. Suggested app contains chest compression feedback function, the map of automated externaldefibrillator (AED), direct emergency call and the basic knowledge of BLS. Using the accelerometer of the smartphone,we implemented a real-time algorithm that estimates the chest compression depth and rate for high qualitycardiopulmonary resuscitation (CPR). The accuracy of algorithm was evaluated by manikin experiment. We madecontents which were easy to learn the BLS for the layperson and implemented a function that provides the AEDlocation information based on the user's current location. From the manikin experiment, the chest compression depthand rate were no significant differences between the manikin data and the app’s feedback data (p > 0.05). DevelopedBLS app was uploaded on Google Play Store and it was free to download. We expected that this app is useful to learnthe BLS for the layperson.??? ????????? 2014?????? ??????(?????????)??? ???????????? ????????????????????? ????????? ?????? ????????? ?????????????????????(No. NRF-2013R1A1A4A0100-6381)
