This observational, multi-center cohort study of pediatric cardiac arrest management will contribute to a clinical CPR Learning Laboratory. The objectives of this study are to characterize the quality of CPR and post-cardiac arrest care delivered to children across a broad spectrum of hospitals, to determine the association between quantitative CPR quality measures (depth, rate, compression release, flow fraction) and survival to hospital discharge, and to determine the association of survival with site-specific post-cardiac arrest care (PCAC). The study will enroll pediatric cardiac arrests requiring chest compressions for ≥1 minute identified as part of standard clinical operations. The CPR quantitative measures, defibrillator data (when available), monitor data (when available), and post-arrest care will be de-identified and submitted to a central database.
