![]() Other: Guidance of the External Chest Compression Other: Rhythm of a relay 4 minutes Condition or diseaseĬardiac Arrest Cardiopulmonary Resuscitation This study should make it possible to clarify the recommendations with a high level of evidence in this field and thus contribute to improving the prognosis of the victims of an out-of-hospital cardiac arrest. The investigators hope by this study to improve the knowledge on the optimal rhythm of the ECC and to validate "in vivo" the interest for the guidance found on manikin. This study should, over a period of 2 years, include 500 patients with cardiac arrest for whom specialized resuscitation is undertaken. The second hypothesis is that a guiding device improves the quality of the ECC. The first assumption is that a 4-minute relay rate improves the CCF (by reducing the No-Flow time) compared to the currently recommended 2-minute relay rate. The investigators formulate two hypotheses that they wish to test simultaneously using a 2x2 factorial design, in a multicenter randomized trial. The investigators propose a study evaluating the efficiency of the guidance of the ECC and the impact of the time of relay on the CCF. Our team studied in simulation the prolonged effects of guidance on the quality of the ECC during a prolonged resuscitation, with encouraging results (Buléon C and Al. Their use is one of the areas of improvement mentioned in the recommendations. They make possible to improve the quality of the ECC achieved (Hostler D and Al. To meet these qualitative needs, ECC guidance devices have been developed. The principle of the chain of survival (early warning - ECC - defibrillation - resuscitation) implies that the deterioration of a single link threaten the whole of the care. The survival of cardiac arrest victims is closely related on this No-Flow time. Improving the chest compression fraction (CCF) by limiting time without cardiac massage (No-Flow) is a second major point of the recommendations (Vaillancourt C and Al. Thus French and international recommendations insist on the central element of external chest compression (ECC) and especially its quality (Monsieurs KG and Al. With an incidence between 5 and 15 per 10,000 (46,000 patients per year in France) and a survival rate of only 5% to 15%, the room for improvement remains significant even today and is based on fast and optimal care. The management of out-of-hospital cardiac arrest is complex and multifactorial. Why Should I Register and Submit Results?.
