description: Sudden cardiac arrest is one of the main causes of death in Europe, with about 700.000 cases each year. In spite of extensive efforts to improve the outcome of cardiac arrest, survival rates remain at a poor level. There is increasing evidence thatin the care of cardiac arrest , the effectiveness of external chest compressions is of crucial importance. However, the growing awareness of the significance of cardiac massage stands in sharp contrast to the often deficient quality of chest compressions as performed by laymen as well as healthcare professionals. The present study examined the influence of a new visual feedback system for external chest compressions on the quality of cardiopulmonal resuscitation applied by healthcare professionals. Primary endpoints were compression depth and frequency, secondary endpoints the percentage of appropriate decompressions and correct compressions and, finally, the sufficiency of each resuscitation effort. In addition, the acceptance of the feedback device by the participants of the study was evaluated. The tested feedback device (prototype by Laerdal, Stavanger, Norway) measures 152mm×64mm×28mm and is designed to be placed between the patient’s chest and rescuer´s palm. A 26mm×26mm colour display provides feedback information. The study was performed in a randomized crossover design. The experimental setup consisted of a training mannequin (Resusci® Anne, Laerdal, Stavanger, Norway) connected to a laptop. For data acquisition, the appropriate software (Laerdal PC Skill Reporting Systems Version 1.3.0) was used. At a two-sided level of significance of 5% and a power of 80%, a calculation based on former studies resulted in a sample size of 96 subjects. This calculation included a dropout rate of 10%. After a random assignment to one of two groups each subject passed twice through the testing assembly. For each test a standardized sequence including two minutes of continuous chest compressions was implemented. Group A was first t…
