Abstract P71: The Benefits of a Simplified Method for CPR Training of Medical Professionals: A Randomized Controlled Study
Objectives: The best method to train lay rescuers in basic life support (BLS) and AED use is unknown. We developed and tested a training method for resuscitation using a defibrillator with “real-time” feedback during simulated cardiac arrest (CA).
Methods: This study randomized 298 subjects into 3 groups in a single blind fashion. All groups received a 2-hour training session followed by a 5 minute simulated CA test scenario. Group 1 was trained and tested with a defibrillator equipped with visual and audible real-time feedback. Group 2 was trained and tested with a defibrillator that did not provide feedback. Group 3 was trained with the feedback defibrillator and was tested using the non-feedback defibrillator. The feedback defibrillator measures chest compression depth and rate, with an accelerometer embedded in a separate sternal pad upon which CPR is performed. Feedback is provided to the caregiver by means of automated verbal prompting and an on-screen hexagonal icon. This icon is a simple visual measure of integrated CPR efficacy, evaluating the depth and frequency of chest compressions and “hands on” time. Quality of CPR performance was measured as the average rate and depth of compressions and the percentage of time compressions were performed (“hands-on”) over 5 minutes. Participant self-assessment of performance was evaluated with a questionnaire.
Results: Groups trained with defibrillator feedback (Groups 1 and 3) provided more effective compressions (depth >1.5 inches) than the group without any defibrillator feedback (Group 2) (Table 1⇓). After training, 63% of all students reported an improvement in their level of comfort with BLS skills. Conclusions: These results suggest that there are benefits to a simple, standardized method of teaching CPR and that training modalities utilizing real-time audiovisual feedback may improve CPR skills and comfort levels.
