Background: Requirements of cardiopulmonary resuscitation must be always prepared and available in emergency ward as the result of acute condition of patients hospitalized in this ward and risk of possible exacerbation in them. Equipping the emergency ward and recruiting expert personnel can effectively reduce the rate of hospital related morbidity and mortality. Materials and Methods: This was a descriptive cross sectional study conducted to evaluate the expertise of the resuscitation team staff, personnel network, and availability of drugs and equipments during cardiopulmonary resuscitation. A questionnaire was used including two main parts. The first part included the data regarding age, sex and underlying diseases and the second part consisted of 67 questions in terms of expertise of the resuscitation team while resuscitating and had 71 scores. Results: The nurse in the resuscitation team was spending an obligatory period of work (Tarh) in 64.4% and the physician was a resident in 91% of the cases. Defibrillator apparatus was in a good condition and working properly in all cases and the period of time using defibrillator from the moment of cardiopulmonary arrest to performing the first shock, was 0.5 to 4 minutes. Regarding availability, amiodarone was least available during resuscitation. Conclusion: According to this study, resuscitation team members in emergency wards of selected centres were not optimally expert in this regard. More researches are recommended in the field of resuscitation and training courses must be held every six months for all members of the treatment team. (Tanaffos 2005; 4(15): 53-56)
