Cardiopulmonary resuscitation (CPR) has been used in hospitals for approximately 40 years. Nurses are generally the first responders to a cardiac arrest and initiate basic life support while waiting for the advanced cardiac life support team to arrive. Speed and competence of the first responder are factors contributing to the initial survival of a person following a cardiac arrest. Attitudes of individual nurses may influence the speed and level of involvement in true emergency situations. This paper uses the theories of reasoned action and planned behaviour to examine some behavioural issues with CPR involvement.
