Introduction: The survival rate of cardiac arrest, has not changed dramatically in the last few decades and remains unacceptably low, which is an essential reason for changes in cardiopulmonary resuscitation. Many studies confirm, that there are no significant differences, between resuscitation with or without passive ventilation in a primary cardiac arrest and that, in certain cases, passive ventilation may indicate a worse outcome of survival. Purpose: The aim was to examine the accessible professional literature in the field of resuscitation and with the help of the study, determine the knowledge of Slovenians included in the research regarding the attitude of Slovenes towards the approach to resuscitation and the willingness to perform passive ventilation, and identify the factors influencing to a restraint for the approach to resuscitation. Methods: In the theoretical part a descriptive method was used, which was based primarily on the study of theory and practical records from domestic and foreign literature, while a survey technique and statistical data processing was used and displayed in the form of tables and graphs. Results: The knowledge about the process of cardiopulmonary resuscitation was acceptably high in the study, which indicates that the participants were familiar with the correct procedures for resuscitation. In 61,7 % of cases, they were ready to perform passive ventilation on anyone who needs resuscitation, although 72 % of respondents knew that it was possible to resuscitate only with chest compressions. The most common reason for not approaching to resuscitate was the fear of making a mistake, which was chosen in 31 % of the participants. The greatest concern, regarding the passive ventilation, was the fear of infectious diseases, that they chose in 39,2 %. Discussion and conclusion: It is necessary to emphasize the various pathophysiological conditions that lead to the need for resuscitation, and to adapt teaching the eyewitnesses that in the case of primary heart failure, passive ventilation may not be necessary. Cardiocerebral resuscitation would be in that case appropriate for all cardiac arrests that occur suddenly in the presence of eyewitnesses.
