To improve the quality of CPR the investigators propose the implementation of a standardized resuscitation team structure with a CPR coach. To date, there have been no studies describing the optimal team structure required for integration of CPR feedback defibrillators during CPA. In this study,the investigators propose the concept of a CPR coach, whose primary responsibility is to provide real-time coaching during cardiac arrest to improve the quality of CPR. Preliminary pilot work done in the intensive care unit at Johns Hopkins Children's Hospital suggests that use of a CPR coach improves the quality of CPR in comparison prior teams that functioned without a CPR coach. This study will assess the impact of a CPR Coach for improving CPR quality and CPR perception in a team of healthcare providers during simulated CPA.
