Abstract 229: Dispatcher-Assisted Cardiopulmonary Resuscitation, Lay People Do Not Perform Effective Treatment
Introduction: Bystander cardiopulmonary resuscitation (CPR) saves lives. A well known method to increase the amount of bystander-initiated CPR is CPR instructions given by the emergency medical dispatchers. We evaluated the action produced by instructions given by the dispatcher for the bystander in a simulated cardiac arrest.
Methods: This observational study included 14 adult voluntaries. A cardiac arrest scenario was presented to the voluntaries and they were provided with telephone compression-only CPR instructions by a dispatcher. The voluntaries were to perform CPR on a Laerdal Rescue-Anne CPR manikin. Recording strips, video and audiotape recordings were analyzed for frequency and quality measures. The dispatchers' performance was also assessed with an objective structured clinical examination (OSCE).
Results: The results showed that the performance of the voluntaries was very poor. It was obvious that many voluntaries understood the instructions very differently from what was the intention by the dispatcher. Median percentage of compressions with adequate depth (38–51 mm) was 28.5%. Average compression rate was 62 (range118–44) per minute.
Conclusions: It is crucial that the instructions given by the dispatcher in a life threatening situation results in right kind of performance by the bystander. Our results show that CPR instructions given following the protocol used today by Swedish dispatchers are not resulting in effective CPR. We need to find ways to instruct bystanders so that they can perform better.
