Cardiac arrest is a sudden failure of the heart’s mechanical activity resulting in a complete disruption of the bloodstream and hypoperfusion of the tissues. It is manifested by loss of consciousness, absence of palpable peripheral pulse and cessation of breathing. Since cardiac arrest is a condition that without rapid intervention certainly ends in mortal outcome, early recognition of the arrest is extremely important as well as the early onset of cardiopulmonary reanimation, defibrillation and the remediation of the reversible causes of the arrest. Early recognition of the symptoms as well as the attempts to rectify the condition constitute the only way to stop this series of events which will inevitably end with a fatal outcome of the victim. All activities undertaken during cardiopulmonary reanimation are aimed at ensuring the recurrence of spontaneous circulation, the establishment of perfusion of the heart and brain and survival of the arrest without neurological damage. Emergency medical service, layman who provides cardiopulmonary resuscitation and the uses of the automatic external defibrillator are all very important factors in the increase of the number of survivors of the cardiac arrest. In most of the world's communities, average arrival time of the emergency medical service is 5-8 minutes and during that time the casualties depend entirely on the cardiopulmonary reanimation provider and the medical dispatch. Therefore, it is necessary to raise awareness and implement knowledge and skills on basic revival in the society in order to be more prepared for cardiopulmonary reanimation and consequently to increase of survival rate of the outside-hospital cardiac arrest. The nurse is an active member of the society who through its work and competences could contribute to raising awareness and teaching the importance of early inception of cardiopulmonary resuscitation, implementation of basic knowledge and revival skills in the society as well as to improve quality of healthcare through all four links in the chain of survival. The methodology of this work has quantitatively examined levels of knowledge and attitudes of University North students’ regarding providing first aid, reanimation and AED defibrillator with a goal of a deeper insight into the existing level of knowledge and attitudes and the possibility of working out for further research and education of lay and non-layman in cardiopulmonary reanimation.
