Ackerman, of Mount Saint Mary College, conducted a study of the cardiopulmonary resuscitation (CPR) knowledge acquisition and retention of baccalaureate nursing students. Using Bennerâ€™s novice to expert theory as framework, the goal was to ascertain whether high-fidelity human patient simulation (HPS) affected CPR knowledge acquisition and 3-month retention compared to traditional CPR certification methods. In addition to demographic data, Ackerman compiled data on participantsâ€™ previous education and experience with CPR on a live person. The study revealed that both groupsâ€™ knowledge retention decreased but, participants who experienced the simulation scenario had better retention than those who did not. Further, participants who had CPR experience with a live person had better scores than either group.
