Abstract 253: Out-of-Hospital Cardiac Arrest Without Return of Spontaneous Circulation in the Field: Who Are the Survivors?

Background: Prompt high quality cardiopulmonary resuscitation is vital for survival from out-of-hospital cardiac arrest (OHCA). Return of spontaneous circulation (ROSC) in the field is one of the most important factors contributing to survival and neurological outcomes following OHCA. Objectives: To describe characteristics of patients with OHCA treated on scene and transported to hospitals in the Dallas-Fort Worth (DFW)Resuscitation Outcomes Consortium (ROC) site, and compare survivors who did and did not have ROSC in the field. Methods: We included OHCA cases ≥18 years old treated and transported to a hospital within the DFW ROC site between 2006 through 2011.We report mean age, sex, EMS witnessed arrest, bystander/EMS shock, response time, attempted cardiopulmonary resuscitation, presenting initial rhythm, survival to hospital discharge for survivors with and without ROSC in the field, as well as for those who met criteria for termination of resuscitation. Results: Included in the study are 5493 OHCA c...
