Abstract 78: Cardiopulmonary and Automatic External Defibrillator handling skills evaluation in lay persons
Background: Since the public access of defibrillation law was approved in Sao Paulo city in 2005, it has been increasing the number of lay people who demand for cardiopulmonary resuscitation (CPR) and Automatic External Defibrillator (AED) training courses. According to the law, subway stations should have an AED and 30 per cent of the Agents should be trained in Heartsaver AED. The American Heart Association advises a Basic Life Support (BLS) refresh every two years. However, recent published papers demonstrated a significant decrease in CPR skills only 6 months following a BLS course.
Hypothesis: we hypothesized that retention of skills in CPR and AED use considerably diminish after 8 month of training in Heartsaver AED course.
Methods: This is an observational prospective study on the retention of CPR and AED handling skills. Twenty Subway Agents who were previously trained in these maneuvers were evaluated . The evaluation of the skills retention was performed 8 months after the success completion of the first Heartsaver AED course, consisting in a cardiopulmonary arrest simulation in a training mannequin. An experienced Heartsaver AED instructor evaluated the following performed skills:
Check for response;
Activate Emergency Response System and Get an AED;
Give two breaths;
Perform compressions hard and fast in a correct hands position;
Results: It was observed that the totality of the participants did not fill, at least, one of the requirements of the evaluation: 85% of the participants checked response, 55% asked for help after check response, 45% asked for help at another moment, 45% opened correctly the airway, 30% checked breathing, 50% gave two breathings, 80% performed 30 compressions, 35% performed compressions in a correct frequency and 60% had performed correct chest place CPR. Concerning the AED use, 30% powered the AED in an appropriated manner and 15% correctly attached the pads but 15% removed the pads after the chock.
Conclusion: The results suggest a possible necessity of a continuous CPR and AED training in view of a significant decreasing in the performance of these skills 8 months following the first training course.
