Bystander vs EMS First–responder CPR: Initial Rhythm and Outcome in Witnessed Nonmonitored Out–of–hospital Cardiac Arrest

摘要: Objectives: To assess whether outcome and first–monitored rhythm for patients who sustain a witnessed, nonmonitored, out–of–hospital cardiac arrest are associated with on–scene CPR provider group. Methods: A retrospective, cohort analysis was conducted in suburban, heterogeneous EMS system. Patients studied were ± 19 years of age, had an presumed origin between July 1989 January 1993, gone into prior to ALS arrival, received on collapse. First–monitored rhythms survival rates compared two patient groups collapse either: 1) by nonprofessional bystanders (BCPR) or 2) system first responders (FRCPR). Results: Of 217 victims, 153 (71%) BCPR 64 (29%) FRCPR. The slightly younger (62. 4 vs 68. years, p = 0. 01) shorter response intervals (6. 7. 7 minutes, 02). There no difference BLS time automatic external defibrillator (AED) use rates. percentage pulseless ventricular tachycardia/ventricular fibrillation (VT/VF) the grouped survived hospital admission discharge were: Controlling odds ratio VT/VF 5. 45 (95% CI 2. 8, 10. 3). Conclusion: receive more often have than do FRCPR patients, despite both CPR–provider groups' initiating essentially immediately after Hence, different rhythms, which may affect rate. These populations should not be considered homogeneous research.
