Cardiac arrest & resuscitation

The association of duration of resuscitation and long-term survival and functional outcomes after out-of-hospital cardiac arrest

ResuscitationPublished Retrospective cohort study

Authors' conclusion

Longer CPR-to-ROSC interval was associated with lower survival at hospital discharge and was influenced by pre-arrest co-morbidities. However, these intervals were not associated with long-term survival or functional outcome among hospital survivors, suggesting early risk of longer CPR-to-ROSC intervals does not persist.
