Refractory CA, once considered uniformly fatal, is now survivable for a defined and growing group of patients. Pooled randomized data confirms clinically meaningful survival advantage for
#ECMO vs standard ACLS in refractory shockable
#OHCA, but neurologically favorable survival steeply falls as low-flow time, with marked deterioration beyond 30-40'. Faster cannulation is associated with survival, and prehospital & hybrid delivery models have demonstrated an increase in access to
#ECLS within the therapeutic window. In parallel, individualized selection integrating rhythm, cardiac arrest characteristics, signs of life + physiologic markers refine candidacy beyond rhythm alone, complementing time-targeted delivery.
