The association between chest compression release velocity and outcomes from out-of-hospital cardiac arrest.

Background: Previous studies have demonstrated significant relationships between cardiopulmonary resuscitation (CPR) quality metrics and survival to hospital discharge from out-of-hospital cardiac arrest (OHCA). Recently, it has been suggested that a new metric, chest compression release velocity (CCRV), may be associated with improved survival from OHCA.

Methods And Results: We performed a retrospective review of all treated adult OHCA occurring over a two year period beginning January 1, 2012.
