Early recognition and intervention in sudden cardiac arrest is crucial for survival. The majority of these cases happen at the victims’ home or in public places, and the first person to act is usually a bystander. The purpose of this study was to assess and to compare bystander’s and third-year medical students’ (who attended first aid courses and training as first year students) knowledge about cardiopulmonary resuscitation in Tîrgu Mureş. Material and methods: We used a questionnaire, which included 28 questions and was filled in voluntarily by 335 people. We investigated previous cardiopulmonary resuscitation (CPR) experience, willingness to help in an emergency situation and basic knowledge about CPR techniques. Results: Only 15% of bystanders were trained in CPR. The majority (94%) of them knew when they have to resuscitate a person and the correct position the person be in. The location of chest compressions was known by 39% of bystanders and by 78% of third-year medical students, the exact rate of chest compressions by 14% of bystanders and by 66% of medical students. 49% of bystanders had driving license, and even though first aid training was required at driving school, their knowledge was barely better than those who did not have one. Conclusions: Bystander’s knowledge on cardiopulmonary resuscitation is generally poor. To improve it, CPR training courses are needed in the community.
