- W11092270 abstract "Background: Recent investigations have demonstrated that CPR performance among trained providers can be improved by audiovisual prompting and real-time feedback, and higher quality CPR before defibrillation can improve shock success and has the potential to improve patient outcomes. Objective: We hypothesized that simplified voice prompts incorporated into an automatic external defibrillator (AED) can lead to improvements in CPR performance by untrained lay rescuers. Methods: Adult volunteers with no prior CPR training were assessed in their use of an AED with chest compression voice instructions and metronome prompts on a CPR-recording manikin. Volunteers were given minimal instructions regarding use of the device and were given no instructions regarding CPR performance. The AED was designed to prompt five cycles of 30 chest compressions between defibrillatory attempts. Chest compression rates and depths were measured via review of videotape and manikin recording data, respectively. Results: A total of 60 adults were assessed in their use of the AED, with a mean age of 33.6±12.8; 36/63 (57%) were female. Mean chest compression rate was 103±12 and mean depth was 37±14 mm. Furthermore, minimal decay in chest compression rates occurred over 5 cycles of chest compressions, with mean rate of 101±19 during the first cycle and 104±10 during the 5 th cycle. No volunteers were unable to use the AED or complete 5 cycles of chest compressions. Conclusions: Our work demonstrates that with appropriate real-time prompts delivered even in the absence of training or human coaching, laypersons can perform CPR that has a quality often similar to trained providers. This finding has important implications for AED design especially in light of the renewed importance of both CPR and the interaction of quality chest compressions and defibrillatory success." @default.
