Until now the only way to review the ongoing reanimation was verbal feedback by the dispatcher on the phone, who has only limited resources in order to review the reanimation process. To overcome this issue, we designed and implemented LifeStream, a system using current smartphone technologies in order to measure reanimation parameters: chest compression rate (CCR) and chest compression depth (CCD). The system is based on a server, web client and mobile application, which gathers, processes and transfers the data. The development of algorithms for CCR and CCD detection as well as the evaluation of the system functionality is part of this paper. We conducted a 2-day user test, where we compared the guided standard reanimation process to the application supported process. The results of the tests showed that it is possible to develop an application, which runs for at least ten minutes (crucial time till ambulance arrives) and enhances the whole reanimation cycle for laypersons and dispatchers (Ljunggren et al., 2016).}, booktitle = {Proceedings of the 10th {Forum} {Media} {Technology} 2017}, publisher = {CEUR-WS}, author = {Grassinger, Florian and Doppler, Jakob and Wagner, Markus and Aigner, Wolfgang}, month = nov, year = {2017}, keywords = {2017, Center for Digital Health Innovation, Center for Digital Health and Social Innovation, Forschungsgruppe Digital Technologies, Forschungsgruppe Media Computing, Institut für Creative Media Technologies, Publikationstyp Präsentation, Publikationstyp Schriftpublikation, health-care, mobile, peer-reviewed, visualization}, pages = {41--45}, }
