Impact of Low-Flow Duration on Favorable Neurological Outcomes of Extracorporeal Cardiopulmonary Resuscitation After Out-of-Hospital Cardiac Arrest

xtracorporeal cardiopulmonary resuscitation (ECPR) is expected to benefit the rescue of selected patients, particularly those who are refractory to conventional cardiopulmonary resuscitation (CPR). Low-flow duration (LFD) is one of the most common criteria to identify candidates for ECPR. 1 However, the association between LFD and favorable neurological outcome has not been sufficiently investigated in out-of-hospital cardiac arrests (OHCAs). This study aimed to assess (1) whether LFD was associated with 1-month survival or favorable neurological outcome after ECPR and (2) the interplay between the documented cardiac rhythms and LFD on neurological outcomes of ECPR.
