Cardiac arrest & resuscitation
Duration of emergency medical services-initiated prehospital cardiopulmonary resuscitation efforts and survival for pediatric patients with out-of-hospital cardiac arrest
Authors' conclusion
In this North American retrospective cohort study of pediatric patients with OHCA, we quantified the time-dependent probability of survival to hospital discharge as a function of prehospital CPR duration.
Study context
- Population
- Children (<18 y) with Emergency Medical Services (EMS)-treated non-traumatic Out-of-hospital Cardiac Arrest (OHCA), Resuscitation Outcomes Consortium Epidemiologic Registry, 10 sites in US and Canada, 2011–2015
- Participants
- 1,313 children
- Outcome
- Survival to hospital discharge, as time-dependent probability by EMS-initiated prehospital CPR duration

Main finding
As reported in the abstract
Time-dependent probability of survival to hospital discharge with ongoing CPR
Probability of survival at 1 min of cardiopulmonary resuscitation (CPR)
7.9%
95% CI 6.4–9.3%
Probability fell below 1% at 14.8 min of CPR
14.8 min
95% CI 11.1–22.0 min
Upper bound of 95% CI fell below 1% at
0.86% 22.0 min
95% CI 0.34–0.94%
Observational data: associations, not effects.
