Feedback During CPR Training and Testing
A "feedback" defibrillator (ZOLL R series) will be used at teaching, immediate testing and 12 week (retention) testing. A simulation manikin with an attached accelerometer pad on its sternum will be used to collect CPR performance data. Subjects will be told to perform compressions on top of the accelerometer pad and will be taught to use and follow the audio and visual feedback to optimize their CPR performance. After training, the raw data collected by the accelerometer will be used as a demonstration and training tool, to correct the subjects' performance by visually demonstrating the difference between ideal and suboptimal CPR performance. Testing will be carried out with the use of a "feedback" defibrillator. Feedback during CPR training: Students in this group will receive training in BLS skills according to the 2005 AHA/ILCOR guidelines, using the ZOLL R Series™ defibrillator with an attached accelerometer pad that will be placed on the sternum of the manikin and visible to
Feedback During CPR Training Not Testing
A "feedback" defibrillator will be used for teaching, with a standard no "feedback" defibrillator used at immediate and 12 week (retention) testing to assess if the techniques the students' learned during training are transferable to devices without "feedback". In order to collect CPR performance data, a simulation manikin with an attached accelerometer pad hidden from view within its chest will be used. Subjects will be told to perform compressions on top of the manikin's chest.

No Feedback Group
A standard no "feedback" defibrillator (ZOLL M series) will be used for teaching, immediate testing and 12 week (retention) testing. In order to collect CPR performance data, a simulation manikin with an attached accelerometer pad hidden from view within its chest will be used. Subjects will be told to perform compressions on top of the manikin's chest. During the test, subjects will be informed that data on their performance will be recorded but they will not be told how this will occur.
