Study designs: Descriptive. Location: Emergency room at Bhumibol Adulyadej Hospital. Population: All CPR cases in emergency room. Study period: 6 month, 19 October 2005-18 April 2006. Results: There are 136 cases of which the majority are males, aged between 60-78 years old. Most of the cases brought to the hospital by their relatives have not undergone the initial CPR by Emergency Medical Service (EMS) team. Among these cases only 38.2 achieves spontaneous circulation. The study shows that the return of spontaneous circulation (ROSC) less than 20 minutes increase outcome of CPR. However, the initial standard CPR at scene is statistically significant in terms of the ROSC (P value \< 0.01).en-USRoyal Thai Airforce, Directorate of Medical Services, ThailandOriginal Articles
